Clay materials play a key role in the production of sanitary ceramics such as washbasins, toilet bowls, bathtubs and other products. These materials provide ceramic products with strength, plasticity and the ability to be shaped into the desired shapes. In addition, they contribute to the aesthetics and functionality of the final products. The high content of clay minerals with a layered structure allows water absorption, which is key to ensuring the necessary stability during drying and firing processing.
