An analysis of the use of ceramic products in the total volume of use of wall materials is given. It is shown that with the plastic method of molding ceramic products, a change in the quality of raw materials can lead to the production of low-quality products (defective products). The basic technological properties of clay raw materials from the Taushinsky deposit in the Perm Territory, as well as its granulometric and mineral compositions, have been studied. It is shown that the adjustment of the composition of the ceramic mixture with a change in the characteristics of the feedstock should be carried out taking into account the features of mineral formation in an 8-component oxide system. A comparison of the physical and mechanical characteristics of two batches of bricks of the current and corrected compositions was made, which makes it possible, with some assumptions, to consider them identical.
