General information and occurrence
The basic raw materials used for a building ceramics production are various clayey rocks which mixed with water form a plastic mass easy to form and sands so-called ‘weaken sands’ which are added to a clayey raw material to improve the properties of the ceramic mass. Formed and burnt products must be of the appropriate physical and technical features defined by the official standards. Clayey and non-clayey (weaken) raw materials often occur together – in one deposit, in the form of beds or inter-beddings, or as independent accumulations.
The assortment of building ceramic products contains mainly: ceramic bricks and breezeblocks, slates, clinker bricks, fittings, ceramic pavements. The raw material from some deposits is being used also for the production of enamel ceramic tiles, stoneware products, ceramic accessories and others.
The raw materials for the building ceramics production owe their yielding features and their ability to be formed to the clayey minerals content. Their content in different rocks varies. In loesses the clayey minerals content is low (couple of %), whereas in clays it can be up to 100 %. Usually, in the typical raw materials the content is between 40 % and 60 %. Other components are mainly sand and quartzitic dust, feldspars, calcite and dolomite in calcareous raw materials, iron minerals, mica minerals and organic matter. Clayey rocks built of only one mineral occur very seldom, they usually have several clayey minerals in their composition: kaolin, illite, montmorillonite and chlorites, occurring together in changeable proportions.
Building ceramics raw materials occur commonly in the whole country. They vary in terms of their origin and age. Nowadays, the most important deposits are these of the Quaternary, Neogene, Jurassic and Triassic age. The raw materials of the Quaternary age include mainly stagnant lake sediments such as muds and clays occurring mainly in northern and central Poland. There are also loesses, glacial loams, alluvial loams and loams of weathering covers and sands used. Among older minerals the most important are the Neogene clays of the so-called Poznań Series from south-western and central Poland and maritime Miocene clays occurring in south-eastern Poland in the area of the Carpathian Foredeep. The Jurassic and Triassic deposits are situated at the margin of the Holy Cross Mts., in the Czestochowa region and in the Opole region. The building ceramics raw materials deposits in Poland are presented on the map.
According to the Regulation of the Minister of the Environment of the 1st of July 2015 regarding the geological documentation of a mineral raw material deposit, excluding a hydrocarbons field (number of Polish act: Dz. U. 2015, poz. 987) the limit values of the parameters that define the building ceramics raw materials deposit and its boundaries (Appendix 8 – table 42) are: – the maximum documentation depth – to the depth of a possible exploitation; – the minimum thickness of the deposit – 2 m; – the maximum overburden/thickness ratio – 0.5; the maximum content of grains bigger than 2 mm – 1 %; – the maximum content of a ceramic marl in grains diameter bigger than 0.5 mm – 0.4 %; – the shrinkage in drying minimum 6 %.
Resources and output
The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
Table 1. Building ceramics raw material – million m3The anticipated economic resources of the building ceramics raw materials amounted to 2,026.509 million m3 (about 4,053.018 million tonnes) as of the end of 2022. They decreased by 4.193 million m3 (about 8.386 million tonnes – that is by 0.2 %) in comparison with the previous year.
There was 1 new deposit of the building ceramics raw materials documented in 2022: the Sągnity 1 deposit (0.227 million m3) located in Warmińsko-Mazurskie Voivodeship. The deposit was allocated from the Sągnity deposit due to planned exploitation only of this part of the deposit.
For 17 deposits there were new documentations with recalculated resources approved (supplements for documentations – 18 supplements, including 2 for the Sągnity deposit), from which:
- new documentations (supplements), updating the boundaries and resources, were elaborated for 12 deposits: Kolonia Spławy II (−0.021 million m3) and Stojeszyn (−0.012 million m3) in Lubelskie Voivodeship, Maciejowice (−0.134 million m3 – the partially exploited area was excluded from the deposit as the area is dedicated for other investments) and Paczków (−0.377 million m3 – a calculation error was corrected) in Opolskie Voivodeship, Chwałowice – Maj V (−0.001 million m3), Chwałowice-Pasztaleniec (0.000 million m3) and Podborze (−0.019 million m3) in Podkarpackie Voivodeship, Szkucin (2.494 million m3 – the deposit area was enlarged), Sągnity (−0.222 million m3 – resources were updated and the Sągnity 1 deposit was allocated), Czacz I (0.000 million m3), Czajcze (0.001 million m3). The resources balance resulted from the above mentioned changes is positive and amounts to 1.709 million m3;
- there were 6 deposits crossed out from ‘The balance…’ after elaboration of supplements of a settlement specification: Rudak I (−1.826 million m3 – exploitation of the Pliocene clays ended due to spatial development plan limitations and due to quality of the raw material not sufficient enough for building ceramics production) in Kujawsko-Pomorskie Voivodeship, Dębówka (−0.966 million m3 – actual and planned land development) and Bojanówka I (−0.041 million m3 – exploitable resources were depleted) in Lubelskie Voivodeship, Siedlisko (−1.233 million m3 – a part of the deposit planned for buildings, the deposit has not been exploited so far) in Lubuskie Voivodeship, Grabowiec (−0.025 million m3 – exploitable resources were depleted) in Świętokrzyskie Voivodeship and Marcinowo (−0.029 million m3) in Warmińsko-Mazurskie Voivodeship. The total resources drop resulting from crossing out the above mentioned deposits is equal 4.120 million m3.
Out of the total 1,111 documented deposits of the building ceramics raw materials, exploited deposits (96) account for 8.6 % (including: 5.7 % deposits exploited continuously (64) and 2.9 % deposits exploited temporarily – 32), non-exploited deposits (299) account for 26.9 % (including: 20.2 % deposits covered by a detailed exploration (225) and 6.7 % deposits covered by a preliminary exploration – 74) and abandoned deposits (716) account for 64.4 %.
Similarly, out of the total volume of the anticipated economic resources (2,026.51 million m3): the resources within exploited deposits (225.27 million m3) account for 11.1 % (including: 10.0 % deposits exploited continuously (202.07 million m3) and 1.1 % deposits exploited temporarily – 23.2 million m3), the resources within non-exploited deposits (1,441.41 million m3) account for 71.1 % (including: 11.2 % in the deposits covered by a detailed exploration (227.87 million m3) and 59.9 % in the deposits covered by a preliminary exploration – 1,213.54 million m3) and the resources within abandoned deposits (359.83 million m3) account for 17.8 %.
The resources documented in A+B and C1 categories (the detailed exploration) account for 34.5 % of total anticipated economic resources. The remaining part of resources is documented in C2 or D categories (the preliminary exploration). More than a half of resources covered by the preliminary exploration (60 %) are resources documented within the overburden of non-exploited brown coal deposit Legnica-pole Wschodnie (727.65 million m3 of clays documented in C2 category).
The economic resources are documented for 58 deposits and amount to 133.892 million m3 in total (about 267.784 million tonnes) that accounts for 56.0 % of the anticipated economic resources of these deposits. The economic resources in 2022 decreased by 6.839 million m3 (4.9 %) in comparison with the previous year, including:
- resources growth by 0.579 million m3, including: Przysieka Stara (0.549 million m3 – new deposit development plan) in Wielkopolskie Voivodeship, Paczków (0.021 million m3) in Opolskie Voivodeship, remaining 0.008 million m3);
- resources drops due to exploitation and losses – 1.912 million m3 in total (regarding only 58 deposits with determined economic resources);
- other drops equal 5.506 million m3, including the following deposits: Złocieniec (−0.306 million m3) in Zachodniopomorskie Voivodeship – supplement No. 3 to the deposit development plan); Miękinia (−1.114 million m3) in Dolnośląskie Voivodeship, Złote Góry II (−0.191 million m3) in Łódzkie Voivodeship, Plecewice I (−2.757 million m3) in Mazowieckie Voivodeship – due to the concession extinction and removal of the mining areas; Rudak I (−0.920 million m3) in Kujawsko-Pomorskie Voivodeship – the deposit crossed out from the registry; Zawady (−0.047 million m3) in Mazowieckie Voivodeship, Radymno – pole zachodnie 1 (−0.122 million m3) in Podkarpackie Voivodeship, Blanowice C (−0.049 million m3) and Ogrodzieniec (−0.001 million m3) in Śląskie Voivodeship – data verification.
In 2022, the output of the building ceramics clays was equal 1.803 million m3 (about 3.606 million tonnes) and increased in comparison with 2021 by 0.089 million m3 (5.2 %). The exploitation was being carried out from 66 deposits (including 2 abandoned deposits). The biggest output was recorded for the Oleśnica 1 deposit in Świętokrzyskie Voivodeship – 0.219 million m3. Considering particular Voivodeships, the output was as follows (in a descending sequence): in Świętokrzyskie Voivodeship 0.427 million m3 (23.7 % of the domestic output); in Dolnośląskie Voivodeship 0.289 million m3 (16.0 %); in Śląskie Voivodeship 0.223 million m3 (12.4 %); in Podkarpackie Voivodeship 0.195 million m3 (10.8 %); in Małopolskie Voivodeship 0.130 million m3 (7.2 %), in Opolskie Voivodeship 0.105 million m3 (5.8 %); in Pomorskie Voivodeship 0.104 million m3 (5.8 %); in Mazowieckie Voivodeship 0.100 million m3 (5.6 %); in Wielkopolskie Voivodeship 0.074 million m3 (4.1 %); in Lubuskie Voivodeship 0.059 million m3 (3.3 %); in Lubelskie Voivodeship 0.049 million m3 (2.7 %); in Podlaskie Voivodeship 0.024 million m3 (1.3 %); in Kujawsko-Pomorskie Voivodeship 0.011 million m3 (0.6 %); in Łódzkie Voivodeship 0.011 million m3 (0.6 %); in Warmińsko-Mazurskie Voivodeship 0.001 million m3 (0.1 %); in Zachodniopomorskie Voivodeship the exploitation was not carried out.
The figure given below shows changes in the domestic resources and production of the clay raw material for the building ceramics industry in Poland in the years 1989-2022.
In The balance of prospective mineral resources of Poland, the prognostic resources (category D1) of the building ceramics raw materials were assessed to be equal 1,328 billion m3 within 65 areas, moreover there were 267 prospective areas given (category D2 without the resources assessment)*. The majority of the prognostic resources is formed by the Neogene clays of the Poznań series (45.7 % of the prognostic resources, from which 20 % are the clays accompanying the brown coal deposits), the Miocene marine clays (33.3 %), the stagnant clays (18.3 %) and other (2.7 %). The geographical distribution of the resources is uneven: in Dolnośląskie Voivodeship there is 43.1 % of the resources located, in Podkarpackie Voivodeship 28.2 %, in Podlaskie Voivodeship 9.2 %, in Warmińsko-Mazurskie Voivodeship 5.1 %, in Śląskie, Pomorskie, Świętokrzyskie and Małopolskie Voivodeships – from 2 % to 3 %, and in the remaining Voivodeships – 6.2 % in total. Except for the determined areas, there are also other possibilities for the valuable clayey raw materials discovery.

The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
The anticipated economic resources of the building ceramics raw materials amounted to 2,033.580 million m3 (about 4,067.158 million tonnes) as of the end of 2020. They decreased by 5.055 million m3 (about 10.110 million tonnes – that is by 0.3 %) in comparison with the previous year.
There were 3 new deposits of the building ceramics raw materials documented in 2020: Lublin-Przejrzysta (0.101 million m3) in Lubelskie Voivodeship, Plecewice III (0.133 million m3 of stagnant lake clays, allocated from Plecewice II deposit) in Mazowieckie Voivodeship, Zarzecze-Wojciechowski (0.014 million m3) in Podkarpackie Voivodeship.

There were following deposits crossed out from ‘The balance…’: Bojanówka Zachód (−0.030 million m3) in Lubelskie Voivodeship, Gorzów Wielkopolski (−0.472 million m3) in Lubuskie Voivodeship, Konstancja-Mieszczańska (−2.521 million m3) in Małopolskie Voivodeship, Pniów-Bałdos I (0.000 million m3) in Podkarpackie Voivodeship and Bielszowice II (−0.218 million m3) in Śląskie Voivodeship. The total resources drop amounted to 4.241 million m3.
Out of 1,127 documented deposits of the building ceramics raw materials, exploited deposits (130) account for 11.5 % (including: 7.2 % deposits exploited continuously (81) and 4.3 % deposits exploited temporarily – 81), non-exploited deposits (301) account for 26.7 % (including: 20.1 % deposits covered by a detailed exploration (227) and 6.6 % deposits covered by a preliminary exploration – 74) and abandoned deposits (696) account for 61.8 %.
Similarly, out of the total amount of the anticipated economic resources (2,033.58 million m3): the resources within exploited deposits (255.31 million m3) account for 12.6 % (including: 10.4 % deposits exploited continuously (212.06 million m3) and 2.1 % deposits exploited temporarily – 43.25 million m3), the resources within non-exploited deposits (1,443.81 million m3) account for 71.0 % (including: 11.3 % in the deposits covered by a detailed exploration (230.27 million m3) and 59.7 % in the deposits covered by a preliminary exploration – 1,213.54 million m3) and the resources within abandoned deposits (334.47 million m3) account for 16.4 %.
Resources documented in A+B and C1 categories (the detailed exploration) account for 34.5 % of total anticipated economic resources. The remaining part of resources is documented in C2 or D categories (the preliminary exploration). More than a half of resources covered by the preliminary exploration (60 %) are resources documented within the overburden of non-exploited brown coal deposit Legnica-pole Wschodnie (727.65 million m3 of clays documented in C2 category).
The economic resources were documented for 72 deposits and amount to 151.796 million m3 (about 303.592 million tonnes) that accounts for 59.7 % of the anticipated economic resources of these deposits. The economic resources in 2020 decreased by 2.430 million m3 (1.6 %) in comparison with the previous year. The was mainly the result of the exploitation. Moreover, there were economic resources updated for: Rudak 1 deposit in Kujawsko-Pomorskie Voivodeship (−0.854 million m3), Gozdnica deposit in Lubuskie Voivodeship (+0.250 million m3), Kolbuszowa-Kupno in Podkarpackie Voivodeship (+0.872 million m3); there were the economic resources crossed out from ‘The balance…’ from: Krzyż deposit in Małopolskie Voivodeship (−0.698 million m3) and Bojanice deposit in Wielkopolskie Voivodeship (−0.332 million m3) as the result of the mining areas extinction (the exploitation concessions extinction).
In 2020, the output of the building ceramics clays was equal 1.565 million m3 (about 3.130 million tonnes) and decreased in comparison with 2019 by 0.233 million m3 (13.0 %). The exploitation was being carried out from 81 deposits.
Considering particular Voivodeships, the output was as follows (in a descending sequence): in Świętokrzyskie Voivodeship 0.334 million m3 (21.4 % of the domestic output); in Małopolskie Voivodeship 0.199 million m3 (12.7 %); in Śląskie Voivodeship 0.187 million m3 (11.9 %); in Dolnośląskie Voivodeship 0.174 million m3 (11.1 %); in Podkarpackie Voivodeship 0.114 million m3 (7.3 %), in Pomorskie Voivodeship 0.088 million m3 (5.6 %); in Opolskie Voivodeship 0.086 million m3 (5.5 %); in Mazowieckie Voivodeship 0.080 million m3 (5.1 %); in Wielkopolskie Voivodeship 0.078 million m3 (5.0 %); in Lubelskie Voivodeship 0.062 million m3 (4.0 %); in Zachodniopomorskie Voivodeship 0.044 million m3 (2.8 %); in Lubuskie Voivodeship 0.039 million m3 (2.5 %); in Kujawsko-Pomorskie Voivodeship 0.035 million m3 (2.2 %); in Łódzkie Voivodeship 0.025 million m3 (1.6 %); in Podlaskie Voivodeship 0.010 million m3 (0.7 %); in Warmińsko-Mazurskie Voivodeship 0.010 million m3 (0.6 %).
The figure given below shows changes in the domestic resources and production of the clay raw material for the building ceramics industry in Poland in the years 1989-2020.
In The balance of prospective mineral resources of Poland, the prognostic resources (category D1) of the building ceramics raw materials were assessed to be equal 1,328 billion m3 within 65 areas, moreover there were 267 prospective areas described (category D2 without the resources assessment)*. The majority of the prognostic resources is formed by the Neogene clays of the Poznań series (45.7 % of the prognostic resources, from which 20 % are the clays accompanying the brown coal deposits), the Miocene marine clays (33.3 %), the stagnant clays (18.3 %) and other (2.7 %). The geographical distribution of the resources is uneven: in Dolnośląskie Voivodeship there is 43.1 % of the resources located, in Podkarpackie Voivodeship 28.2 %, in Podlaskie Voivodeship 9.2 %, in Warmińsko-Mazurskie Voivodeship 5.1 %, in Śląskie, Pomorskie, Świętokrzyskie and Małopolskie Voivodeships – from 2 % to 3 %, and in the remaining Voivodeships – 6.2 % in total. Except for the determined areas, there are also other possibilities for the valuable clayey raw materials discovery.

General information and occurrence
The basic raw materials used for a building ceramics production are various clayey rocks which mixed with water form a plastic mass easy to form and sands so-called ‘weaken sands’ which are added to a clayey raw material to improve the properties of the ceramic mass. The formed and burnt products must be of the appropriate physical and technical features defined by the official standards. Clayey and non-clayey (weaken) raw materials often occur together – in one deposit, in the form of beds or interbeddings, or as the independent accumulations.
The main building ceramic products are: ceramic bricks and breezeblocks, slates, clinker bricks, fittings, ceramic pavements. The raw material from some deposits is being used also for the production of enamel ceramic tiles, stoneware products, ceramic accessories and others.
The raw materials for the building ceramics production owe their yielding features and their ability to be formed to the clayey minerals content. Their content in different rocks varies. In loesses the clayey minerals content is low (couple of %), but in clays it can be up to 100 %. Usually in the typical raw materials the content is between 40 % and 60 %. Other components are mainly the quartzitic sand and dust, feldspars, calcite and dolomite in calcareous raw materials, iron minerals, mica minerals and organic matter. Clayey rocks built of only one mineral occur very seldom, they mostly have several clayey minerals in their composition: kaolin, illite, montmorillonite and chlorites, occurring together in changeable proportions.
Building ceramics raw materials occur commonly in the whole country. They vary in terms of their origin and age. Nowadays, the most important raw materials are these of the Quaternary, Neogene, Jurassic and Triassic age. The raw materials of the Quaternary age include mainly stagnant lake sediments such as muds and clays occurring mainly in northern and central Poland. There are also loesses, glacial loams, alluvial loams and loams of weathering covers and sands used. Among older minerals the most important are the Neogene clays of the so-called Poznań Series from south-western and central Poland and those of the Krakowiec clays from the area of the Carpathian Foredeep in south-eastern Poland. The Jurassic and Triassic deposits are situated at the margin of the Holy Cross Mts., in the Czestochowa region and in the Opole region. The building ceramics raw materials deposits in Poland are presented on the map.
According to the Regulation of the Minister of the Environment of the 1st of July 2015 regarding the geological documentation of a mineral raw material deposit, excluding a hydrocarbons field (number of Polish act: Dz. U. 2015, poz. 987) the limit values of the parameters that define the building ceramics raw materials deposit and its borders (Appendix 8 – table 42) are: – the maximum documentation depth – to the depth of a possible exploitation; – the minimum thickness of the deposit – 2 m; – the maximum overburden/thickness ratio – 0.5; the maximum content of grains bigger than 2 mm – 1 %; – the maximum content of a ceramic marl in grains diameter bigger than 0.5 mm – 0.4 %; – the shrinkage in drying minimum 6 %.
Resources and output
The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
The anticipated economic resources of the building ceramics raw materials amounted to 2,038.635 million m3 (about 4,077.270 million tonnes) as of the end of 2019. They decreased by 5.617 million m3 (about 11.234 million tonnes – that is by 0.3 %) in comparison with the previous year.
There were not any new deposits of the building ceramics raw materials documented in 2019, however there were 22 new documentations with recalculated resources approved, including: 14 supplements updating the deposits boarders and resources, and 8 supplements with resources settlements.
The new documentations with updated boarders and resources, were elaborated for the following deposits: Ruszowice II (−0.006 million m3) in Dolnośląskie Voivodeship, Słodków – Stróża (0.020 million m3), Słodków IV (0.065 million m3) and Suchynia II (0) in Lubelskie Voviodeship, Łukowa I (−0.015 million m3) in Małopolskie Voivodeship, Czerwone Osiedle (1.395 million m3) and Konradów Głuchołaski (−0.107 million m3) in Opolskie Voviodeship, Zalesie Gorzyckie – Dul 8 (0), Zalesie Gorzyckie – Dul VII (0), Zalesie Gorzyckie – Dul III (0) in Podkarpackie Vovivodeship, Sierakowice (−1.545 million m3) in Śląskie Voivodeship, Odonów (−1.118 million m3) in Świętokrzyskie Voivodeship and Bukowo (Wschód) (−0.010 million m3) and Złocieniec (−0.063 million m3) in Zachodniopomorskie Voivodeship.
The supplements with the resources settlement, where the basis for crossing out 9 deposits from ‘The balance…’: Dąbrowa II (−0.042 million m3) in Łódzkie Voivodeship, Bonarka-Łagiewniki (−2.045 million m3) and Krościenko (−0.092 million m3) in Małopolskie Voivodeship, Guzowatka III/1 (−0.030 million m3), Babiec Piaseczny II (−0.000 million m3) and Mokre – dz. Nr 373/2 (−0.041 million m3) in Mazowieckie Voivodeship, Gorzyce – Cetnarski II (−0.004 million m3) in Podkarpackie Voivodeship, Świba (−0.020 million m3) and Słupia (−0.033 million m3) in Wielkopolskie Voviodeship. The total resources drop amounted to 2,265 million m3. The significant resources volume of Bonarka-Łagiewniki were crossed out from ‘The balance…’ due to ‘the raw material quality – the high sulfate salts content, the deteriorating quality of products as the result of the mine location in the center of Cracow town’. Babiec Piaseczny II deposit was crossed out from ‘The balance…’ due to the resources depletion. In other cases, there were the geological reasons: the bad raw material quality and difficult geological-mining conditions, and economic reasons: the resignation of the exploitation process (probably due to the unprofitable of the ceramic articles production) and the plans to the land development for other purposes.
Out of 1,133 documented deposits of the building ceramics raw materials, exploited deposits account for 12.7 % (including: 7.5 % deposits exploited continuously and 5.2 % deposits exploited temporarily), non-exploited deposits account for 26.7 % (including: 20.1 % deposits covered by a detailed exploration and 6.6 % deposits covered by a preliminary exploration) and abandoned deposits account for 60.6 %.The number of abandoned deposits – reported in the domestic records – has been increasing systematically for many years.
Out of the total amount of the anticipated economic resources, the resources within exploited deposits account for 12.4 % (including: 10.6 % deposits exploited continuously and 1.6 % deposits exploited temporarily), the resources within non-exploited deposits account for 71.2 % (including: 11.4 % in the deposits covered by a detailed exploration and 59.8 % in the deposits covered by a preliminary exploration) and the resources within abandoned deposits account for 16.4 %.
Resources documented in A+B and C1 categories (the detailed exploration) account for 34.5 % of total anticipated economic resources. The remaining part of resources is documented in C2 or D categories (the preliminary exploration). More than a half of resources covered by the preliminary exploration (59.7 %) are resources documented within the overburden of non-exploited brown coal deposit Legnica-pole Wschodnie (727.65 million m3 of clays documented in C2 category).
The economic resources were documented for 74 deposits and amounted to 154.226 million m3 (about 308.452 million tonnes) that accounts for 60.2 % of the anticipated economic resources of these deposits. The economic resources in 2019 increased by 17.946 million m3 (13.2 %) in comparison with the previous year. There were the economic resources updated for Gozdnica deposit (the resources drop was recorded in 2018), Oleśnica 1 deposit (+21.543 million m3), Wola Rzędzińska (−6.047 million m3 were reclassified to the sub-economic resources). There were the economic resources established for Kębłowo Nowowiejskie II deposit (+4.744 million m3). The resources of Hadykówka deposit were crossed out from ‘The balance…’ due to the abolition of the mining area (−1.508 million m3).
In 2019, the output of the building ceramics clays was equal 1.798 million m3 (about 3.596 million tonnes) and decreased in comparison with 2018 by 0.244 million m3 (12.0 %). The exploitation was being carried out from 85 deposits.
Considering particular Voivodeships, the output was as follows (in a descending sequence): in Świętokrzyskie Voivodeship 0.357 million m3 (19.9 % of the domestic output); in Śląskie Voivodeship 0.241 million m3 (13.4 %); in Podkarpackie Voivodeship 0.211 million m3 (11.7 %); in Małopolskie Voivodeship 0.157 million m3 (8.7 %); in Dolnośląskie Voivodeship 0.143 million m3 (7.9 %), in Mazowieckie Voivodeship 0.130 million m3 (7.2 %); in Opolskie Voivodeship 0.117 million m3 (6.5 %); in Pomorskie Voivodeship 0.104 million m3 (5.8 %); in Wielkopolskie Voivodeship 0.075 million m3 (4.2 %); in Lubuskie Voivodeship 0.064 million m3 (3.6 %); in Zachodniopomorskie Voivodeship 0.064 million m3 (3.6 %); in Lubelskie Voivodeship 0.060 million m3 (3.3 %); in Łódzkie Voivodeship 0.032 million m3 (1.8 %); in Podlaskie Voivodeship 0.031 million m3 (1.7 %); in Warmińsko-Mazurskie Voivodeship 0.008 million m3 (0.4 %); in Kujawsko-Pomorskie Voivodeship 0.004 million m3 (0.2 %).

The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
Anticipated economic resources of building ceramics raw materials amounted to 2,044.252 million m3 (about 4,088.504 million tonnes) as of the end of 2018. They increased by 13.372 million m3 (about 26.744 million tonnes – 0.7 %) in comparison with the previous year.
There were 3 newly documented deposits included in ‘The balance…’: Sośnica 1 (0.307 million m3) located in Dolnośląskie Voivodeship – the deposit was allocated from Sośnica deposit, Rojów II (0.033 million m3) located in Wielkopolskie Voivodeship and Gnaszyn – Północ located in Śląskie Voivodeship (4.462 million m3).
In 2018 there were 27 new documentations with recalculated resources approved. Most of them were elaborated in the result of the exploitation end or the expiry date of the concession, in order to the resources settlement (21 documentations). Other documentations are related to: the enlargement of a deposit area (3), the enlargement of a deposit area and a change of the raw material usage (1), the updating of resources in the result of a deposit division (1), the updating of resources according to new balancing criteria (1).
The significant resources growths were recorded in the deposits for which the border have been enlarged: Kolbuszowa-Kupno (12.286 million m3) located in Podkarpackie Voivodeship and Sierakowice (1.770 million m3) located in Śląskie Voivodeship. The important increases were also the result of the resources updating of Lajsy deposit (0.228 million m3) located in Warmińsko-Mazurskie Voivodeship, Pieńkowo II deposit (0.020 million m3) located in Zachodniopomorskie Voivodeship and Bojanice deposit (0.011 million m3) located in Wielkopolskie Voivodeship.
The biggest resources drops occurred in the following deposits: Buśno (0.976 million m3) – the raw material was reclassified into the chapter Clay raw materials for cement production, Gozdnica (0.819 million m3) – in the result of the resources updating according to the current parameters that define the deposit and its borders, Sośnica (0.523 million m3) after the allocation of Sośnica 1 deposit, Lipie Śląskie – Lisowice (0.109 million m3) and Głogówek (0.025 million m3).
There were 14 deposits crossed out from ‘The balance…’: Wola Bachorska I (0.047 million m3) located in Łódzkie Voivodeship; Gaboń-Grabie (0.085 million m3), Hebdów (0.508 million m3), Stróże (0.030 million m3) located in Małopolskie Voivodeship; Drwały (0.004 million m3), Guzowatka III (0.077 million m3), Kobyłka Kolonia Chór 5 (0.033 million m3), Małopole III (0.050 million m3), Mokre IV (0.125 million m3), Mokre – Truszkowski, Kryski (0.106 million m3) located in Mazowieckie Voivodeship; Wrzawy – Laskowski I (0 million m3) located in Podkarpackie Voivodeship; Wyszyna Fałkowska I (0.163 million m3), Wyszyna Fałkowska II (0.000 million m3 – in the deposit there were only anticipated sub-economic resources documented and exploited) located in Świętokrzyskie Voivodeship; Guzy III (0.000 million m3) located in Warmińsko-Mazurskie Voivodeship. The total resources drop resulted from crossing out the above mentioned deposits was equal 1.228 million m3.
The resources of Buśno deposit (0.976 million m3 – the building ceramics raw material) were reclassified into the chapter Clay raw materials for cement production due to the change of the raw material usage. From the loessal loams of this deposit the ceramic brick was being produced from ‘60s of the 20th century till 2012. Then, this type of production was abandoned and the raw material started to being used for the production of the cement clinker in the Chełm cement plant. The reclassification – the change of the raw material type – was based on the new documentation with recalculated resources elaborated for loessal loams deposit Buśno, intended for the cement production. The documentation was approved in 2018 and resulted in the resources updating and the extension of the previous deposits borders.
Out of 1,148 documented deposits of building ceramics raw materials, exploited deposits account for 13.4 % (including: 8.8 % deposits exploited continuously and 4.6 % deposits exploited temporarily), non-exploited deposits account for 26.7 % (including: 20.2 % deposits covered by a detailed exploration and 6.4 % deposits covered by a preliminary exploration) and abandoned deposits account for 59.9 %.The number of abandoned deposits – reported in the domestic records – has been increasing systematically for many years.
Out of the total amount of the anticipated economic resources, the resources within exploited deposits account for 12.4 % (including: 10.8 % deposits exploited continuously and 1.6 % deposits exploited temporarily), the resources within non-exploited deposits account for 71.0 % (including: 11.4 % in the deposits covered by a detailed exploration and 59.6 % in the deposits covered by a preliminary exploration) and the resources within abandoned deposits account for 16.6 %.
Resources documented in A+B and C1 categories (the detailed exploration) account for 34.7 % of total anticipated economic resources. The remaining part of resources is documented in C2 or D categories (the preliminary exploration). More than a half of resources covered by the preliminary exploration (54.5 %) are resources documented within the overburden of non-exploited brown coal deposit Legnica-pole Wschodnie (727.65 million m3 of clays documented in C2 category).
Economic resources were documented for 74 deposits and amounted to 136.280 million m3 (about 272.560 million tonnes) that accounts for 52.5 % of anticipated economic resources of these deposits. The economic resources decreased by 4.533 million m3 (3.2 %) in comparison with the previous year mainly as a result of the crossing out the economic resources from ‘The balance…’ for these deposits for which the exploitation concessions extinct.
In 2018, the output of building ceramics clays was equal 2.042 million m3 (about 4.084 million tonnes) and increased in comparison with 2017 by 0.498 million m3 (32.3 %). It was the highest output level in the last few years: in the 2012-2017 period, the exploitation remained in the range between 1.518-1.950 million m3, 1.915 million m3 at the average.
In terms of a genetic origin, the output is as follows: the Neogene clays of the so-called Poznań Series 0.668 million m3 (accounting for 32.7 % of the total output), the Miocene clays of the Carpathian Foredeep 0.584 million m3 (28.6 %), the Quaternary stagnant lake clays 0.329 million m3 (16.1 %), the Triassic clays 0.194 million m3 (9.5 %), the Jurassic clays 0.193 million m3 (9.5 %), other clays in total 0.073 million m3 (3.6 %).

Main raw materials used for a building ceramics production are various clay rocks which mixed with water form a plastic mass easy to form and sands so-called ‘weaken sands’ which are added to a clayey raw material to improve the properties of the ceramic mass. Formed and burnt products must be of the appropriate physical and technical features defined by the official standards. Clay and non-clay (weaken) raw materials often occur together – in one deposit, in the form of beds or interbeddings, or as the independent accumulations.
The main building ceramic products are: ceramic bricks and breezeblocks, slates, clinker bricks, ceramic pavements. The raw material from some deposits is being used for the production of ceramic tiles, stoneware products, ceramic accessories and others.
Raw materials for the building ceramics production contain clayey minerals. Their content in different rocks varies. In loesses the clayey minerals content is low (couple of %), but in clays it can be 100 %. Usually the content is between 40 % and 60 %. Other components are mainly quartz sand and dust, feldspars, calcite and dolomite in calcareous raw materials, iron minerals, mica minerals and organic matter. Clayey rocks built of only one mineral are very seldom, they mostly have several clayey minerals in their composition: kaolin, illite, montmorillonite and chlorites, occurring together in changeable proportions.
Building ceramics raw materials occur in the whole country. They vary in terms of their origin and age. Nowadays, the most important raw materials are these of the Quaternary, Neogene, Jurassic and Triassic age. Raw materials of Quaternary age include mainly stagnant lake sediments such as muds and clays occurring mainly in northern and central Poland. There are also loesses, glacial tills, alluvial sediments and those of weathering covers and sands used. Among older minerals the most important are Neogene clays of the so-called Poznań Series from south-western and central Poland and those of the Krakowiec clays from the area of the Carpathian Foredeep in south-eastern Poland. The Jurassic and Triassic deposits are situated at the margin of the Holy Cross Mts. and in the Czestochowa and Opole regions. Building ceramics raw materials deposits in Poland are presented on the map.
According to the Regulation of the Minister of the Environment of the 1st of July 2015 (number of Polish act: Dz. U. 2015, poz. 987) the limit values of the parameters that defines the deposit (Appendix 8 – table 42) are: the maximum documentation depth – to the depth of a possible exploitation; the minimum thickness of the deposit – 2 m; the maximum overburden/thickness ratio – 0.5; the maximum content of grains bigger than 2 mm – 1 %; the maximum content of ceramic marl with grains diameter bigger than 0.5 mm – 0.4 %; the shrinkage in drying – minimum 6 %.
The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
Anticipated economic resources of building ceramics raw material amounted to 2,030.880 million m3 in 2017 (about 4,061.760 million tonnes) and decreased by 1.802 million m3 (about 3.604 million tonnes – 0.1 %) in comparison with the previous year.
There were 4 new deposits documented in 2017: Bukówek in Dolnośląskie Voivodeship with anticipated economic resources equal 2.099 million m3, Markowicze I in Lubelskie Voivodeship with resources equal 5.510 million m3, Trześń-Łabuda IV in Podkarpackie Voivodeship with resources equal 0.031 million m3 and Witaszyce 1 in Wielkopolskie Voivodeship with resources equal 0.306 million m3. The latest one was allocated from Witaszyce deposit.
There were 22 new documentations with recalculated resources approved in 2017.
There were 11 deposits crossed out from ‘The balance…’ of which for 10 deposits there were new documentations with resources settlement approved and only Racibórz 1 i 2 deposit was crossed out due to the verification of documents issued in 1997. In Dolnośląskie Voivodeship there was 1 deposit crossed out: Ścinawka Średnia – the resources drop equal 1.759 million m3; in Lubuskie Voivodeship 1 deposit: Budych I – the resources drop equal 3.414 million m3; in Małopolskie Voivodeship 1 deposit: Wadowice-Łazówka – the resources drop equal 0.335 million m3; in Mazowieckie Voivodeship 3 deposits: Ciemne VI, Marki – Lisa Kuli 69 and Nowe Słupno V – the total resources drop equal 0.122 million m3; in Podkarpackie Voivodeship 1 deposit: Wrzawy – Woźniak III – the resources drop equal 0.003 million m3; in Śląskie Voivodeship 2 deposits: Racibórz and Racibórz 1 i 2 – the total resources drop equal 0.085 million m3; in Świętokrzyskie Voivodeship 1 deposit: Wyszyna Machorowska II – the resources drop equal 0.046 million m3; in Wielkopolskie Voivodeship 1 deposit: Wysoka – the resources drop equal 0.026 million m3. The anticipated economic resources of the deposits mentioned above amounted to 5.789 million m3.
Pęglity deposit, located in Warmińsko-Mazurskie Voivodeship, was moved to the chapter Sand and gravel with anticipated economic resources of the deposit equal 0.353 million m3. The sands documented in this deposit meet the criteria for building sands but were exploited and used as a weaken raw material for the building ceramic production by a nearby ceramic factory. Therefore, the deposit was classified as a building ceramics raw material. Nowadays, due to the exploitation abandonment and the brick factory liquidation, the raw material qualification has changed.
Out of the total anticipated economic resources 12.3 % are resources within exploited deposits, 71.3 % resources within non-exploited deposits (from that 11.6 % within deposits covered by a detailed exploration and 59.7 % within deposits covered by a preliminary exploration) and 16.4 % resources within abandoned deposits.
Out of 1,157 documented deposits of building ceramics clays 15.5 % are exploited deposits (including 8.3 % deposits exploited continuously and 7.2 % – exploited temporarily), 26.5 % non-exploited deposits (including 20.1 % deposits covered by a detailed exploration and 6.4 % – covered by a preliminary exploration) and 58.0 % abandoned deposits.
Resources documented in A+B and C1 categories (the detailed exploration) account for 34.5 % of total anticipated economic resources. The remaining part of resources is documented in C2 or D categories (the preliminary exploration). More than a half of resources covered by the preliminary exploration (54.7 %) are resources documented within the overburden of non-exploited brown coal deposit Legnica-pole Wschodnie (727.65 million m3 of clays documented in C2 category).
Economic resources were documented within 85 deposits and amounted to 140.813 million m3 (about 281.626 million tonnes) that accounts for 55.0 % of anticipated economic resources of these deposits. The resources decreased by 13.404 million m3 (8.7 %) in comparison with the previous year mainly as a result of the extinction of the abandoned deposits exploitation concessions.
In 2017, the output of building ceramics clays was equal 1.544 million m3 (about 3.088 million tonnes). It means that the production decreased by 0.038 million m3 (2.4 %) in comparison with the previous year. The output of building ceramics raw materials is characterized by a declining tendency over the recent years and the amount recorded in 2017 was the lowest one over the several dozen years. Moreover, the part of the given output was used for other purposes than the production of building ceramics: 0.058 million m3 of clay and clay slate from Biecz 1 deposit was used for the flood banks building and 0.029 million m3 of loess raw material from Buśno deposit was used for the cement clinker kiln.
The low level of the output and the growing intensity of the searching of the alternative building raw materials uses are the result of the changes in the ceramic industry and the market. The liquidation of the consecutive ceramic factors is caused by: – the domination of the large-sized products; – the lower raw material consumption per a ceramic unit; – the growing competition of other building materials; – the progress of the building technology together with the low production profitability and the difficulties with the products sales. These factors determine the problems for factories in coping with the current economy conditions. Moreover, these factors cause also the loss of the deposits value as ceramic raw materials or as mineral in general, because they cannot be used for any other purpose. Such a situation is a base for the geological administration authorities to initiate the procedure of crossing the deposit and its non-exploited resources out from the national registry to make the areas enable for other purposes.
Considering particular voivodeships, the output was as follows (in a descending sequence): in Świętokrzyskie Voivodeship 0.250 million m3 (16.2 % of the domestic output); in Małopolskie Voivodeship 0.193 million m3 (12.5 %); in Dolnośląskie Voivodeship 0.173 million m3 (11.2 %); in Podkarpackie Voivodeship 0.155 million m3 (10.1 %); in Mazowieckie Voivodeship 0.150 million m3 (9.7 %); in Śląskie Voivodeship 0.149 million m3 (9.7 %); in Opolskie Voivodeship 0.095 million m3 (6.2 %); in Pomorskie Voivodeship 0.092 million m3 (6.0 %); in Wielkopolskie Voivodeship 0.081 million m3 (5.3 %); in Lubelskie Voivodeship 0.079 million m3 (5.1 %); in Lubuskie Voivodeship 0.046 million m3 (3.0 %); in Łódzkie Voivodeship 0.040 million m3 (2.6 %); in Kujawsko-Pomorskie Voivodeship 0.019 million m3 (1.3 %); in Podlaskie Voivodeship 0.010 million m3 (0.6 %); in Warmińsko-Mazurskie Voivodeship 0.009 million m3 (0.6 %) and in Zachodniopomorskie Voivodeship 0 million m3 (0.0 %). Zachodniopomorskie Voivodeship is the only one without production (since 2012).

Main raw materials used for building ceramics production are clay rocks. Their suitability depends on their plasticity after they are mixed with water. If the plasticity is too high, the mix is corrected by adding such ingredients as sand, crushed brick and fly ash and sawdust. Clay and non-clay raw materials very often occur together – in one deposit.
The main building ceramic products are: ceramic bricks and breezeblocks, slates, clinker bricks, ceramic pavements.
Mineral raw materials used in the industry of building ceramics are varying in age and origin. Raw materials currently exploited for the needs of that industry in Poland come from deposits ranging in age from Permian to Quaternary.

Building ceramics raw materials deposits in Poland are presented on the map.
According to the Regulation of the Minister of the Environment of the 22nd of December 2011 (number of Polish act: Dz. U. Nr 291, poz. 1712.) the limit values of the parameters that defines the deposit are: – the maximum documentation depth – to the depth of possible exploitation; – the minimum thickness of the deposit – 2 m; – the maximum overburden/thickness ratio – 0.5; the maximum content of grains bigger than 2 mm – 1 %; – the maximum content of ceramic marl with grains diameter bigger than 0.5 mm – 0.4 %; – the shrinkage in drying minimum 6 %. These limit values have not changed in comparison to the previous ‘balancing criterias’ (obtaining since the 1st of January 2002 to 31st of December 2011).
The table given below shows reserves and the state of development and exploration of clay raw material for the building ceramics industry.
Anticipated economic resources amounted to 2,043.07 million m3 in 2014 (about 4,086.14 million tonnes) and decreased by 0.45 million m3 (about 0.90 million tonnes – 0.02 %).
There were 2 new deposits documented (+0.183 million m3): Barcik 10 in Mazowieckie Voivodeship (with resources equal 0.170 million m3) and Pniów-Bałdos I in Podkarpackie Voivodeship (with resources of equal 0.013 million m3).
There were also 22 new documentations approved for documented deposits – due to the exploitation ending or deposit boundaries changes.
There were 15 deposits crossed out of ‘The balance…’ (−1.590 million m3): including: 4 deposits in Dolnośląskie Voivodeship (Pęgów, Proszówka, Słupiec, Trzebnica), 1 in Lubelskie Voivodeship (Kraśnik-Suchynia W), 1 in Małopolskie Voivodeship (Tropie Góry 2), 3 in Mazowieckie Voivodeship (Kobyłka-Maciołki DM, Marki Wesoła 57, Słupno-Wawrzynów 2), 1 in Opolskie Voivodeship (Skarbiszowice III), 3 in Podkarpackie voivodeship (Gorzyce-Korga, Wrzawy – Laskowski V, Zalesie Gorzyckie – Dul 6), 1 in Śląskie Voivodeship (Buków A) and 1 in Świętokrzyskie Voivodeship (Ruszcza I).
The boundaries changes caused the amendments of resources (+2.223 million m3) for: Kęty deposit in Małopolskie Voivodeship (−0.433 million m3), Janiszów deposit in Lubelskie Voivodeship (+0.015 million m3), Gaboń-Grabie in Małopolskie Voivodeship (+0.072 million m3), Pniów-Bera VIII (+0.004 million m3) and Wrzawy-Laskowski VI (+0.014 million m3) in Podkarpackie Voivodeship, Opalenie in Pomorskie Voivodeship (+0.514 million m3), Kolosy (+0.165 million m3) and Wyszyna Fałkowska III (+1.439 million m3) in Świętokrzyskie Voivodeship.
The resources increased significantly also in Krotoszyn Stary deposit – by 0.619 million m3. There were also recalculations of resources made for Pogolewo Duże deposit in Dolnośląskie Voivodeship (+0.618 million m3), Przygodzice (pole II I ob.Wysocko) deposit in Wielkopolskie Voivodeship (+0.148 million m3) and Gliwice zakł.nr 3 deposit in Śląskie Voivodeshi (−0.196 million m3).
The resources decreased also due to the exploitation and loesses (−2.065 million m3).
Out of the total anticipated economic resources 19.4 % are resources within exploited deposits, 71.7 % are resources within non-exploited deposits and 15.2 % are resources within abandoned deposits.
Out of 1,201 documented deposits of building ceramics clays, 19.4 % of deposits are exploited (including 11.2 % deposits exploited continuously and 8.2 % – exploited temporarily) and 25.8 % deposits are non-exploited (including 19.7 % deposits covered by detailed exploration and 6.1 % – covered by preliminary exploration). The remaining deposits were abandoned (54.8 %).
Economic resources within 131 deposits amounted to 165.21 million m3 (about 330.42 million tonnes) and increased by 7.59 million m3 (4.8 %) in comparison with the previous year.
In 2014, production of building ceramics clays was equal 1.953 million m3 (about 3.906 million tonnes). It means significant increase (by 0.435 million m3 – 28.7 %) in comparison with the previous year. Traditionally, the biggest production is observed in the southern Poland – Dolnośląskie Voivodeship (0.302 million m3 – 15.5 % of domestic production), Świętokrzyskie Voivodeship (0.269 million m3 – 13.8 % of domestic production), Śląskie Voivodeship (0.230 million m3 – 11.8 % of domestic production), Mazowieckie Voivodeship (0.201 million m3 – 10.3 % of domestic production), Małopolskie Voivodeship (0.192 million m3 – 9.9 % of domestic production) and Podkarpackie Voivodeship (0.187 million m3 – 9.6 % of domestic production). The production from these 6 Voivodeships accounts for 70.8 % of domestic production. The only Voivodeship without production (since 2012) is Zachodniopomorskie voivodeship.
There were also 5 changes of deposit names – Pawice I i II (former: Pawice) in Dolnośląskie voivodeship, Silesia B (former: Silesia) and Pawłów (former: Pawłow) in Śląskie Voivodeship, Kolosy (former: Kolosy 1) in Świętokrzyskie Voivodeship, Przygodzice (pole II I ob.Wysocko) (former: Przygodzice (ob.Wysocko)) in Wielkopolskie Voivodeship, Polanów (former: Polanów I) in Zachodniopomorskie Voivodeship.

Mineral raw materials used in the industry of building ceramics are varying in age and origin. Raw materials currently exploited for the needs of that industry in Poland come from deposits ranging in age from the Permian to Quaternary. The deposits are distributed practically throughout the whole country. However, they are more common and larger in the south also their differentiation appears higher than in other parts of the country.
The main building ceramic products are: ceramic bricks and breezeblocks, slates, clinker bricks, ceramic pavements.
Main raw materials used for building ceramics production are clay rocks. Their suitability depends on their plasticity after they are mixed with water. If the plasticity is too high, the mix is corrected by adding such ingredients as sand, crushed brick and fly ash and sawdust. Clay and non-clay raw materials very often occur together – in one deposit.
Raw materials for building ceramics production contain clayey minerals. In loess clayey minerals content is low (couple of %), but in clays it can be 100 %. Usually the content is between 40-60 %. Other components are quartz sand and dust, feldspars, calcite and dolomite, iron minerals, mica minerals and organic matter.
The most important raw materials of the Quaternary age include stagnant lake sediments such as muds and clays occurring mainly in northern and central Poland as well as loess, glacial tills, alluvial sediments and those of weathering covers and sands. The most important raw materials of the Tertiary age include clays of the so-called Poznań Series from south-western and central Poland and those of the Krakowiec Clays from the area of the Carpathian Foredeep in south-eastern Poland. The Triassic and Jurassic deposits are situated at the margin of the Holy Cross Mts and in the Czestochowa and Opole regions.
