Studied the mineral composition of clay raw materials from 48 deposits of Ukraine, which have industrial application. The influence of the mineral composition of clays on the properties of ceramic materials obtained on their basis has been established. Diagrams are plotted in which areas of the mineral composition of clays with a mass fraction of free quartz from 30 to 50%, suitable for the production of wall and facade ceramics, obtained in the firing temperature range of 950 - 1050 ° C, are highlighted.
