The project is devoted to the study of the ceramic properties of the Orenburg region clay in order to determine the fields of its application in industry. Mineral, chemical, disperse compositions, as well as the sintering properties of the clay sample are determined. It was found that clay of the Orenburg region (Russian Federation) is the main clay with a high content of coloring oxides, medium dispersion, moderate plasticity, good drying, little sensitive to drying. The mineral composition of clay is determined. The main phases are kaolinite, smectite, illite, and quartz. The possible areas of using clay in the ceramics production are determined. This clay can be used to produce ceramic tiles of groups AII (b-1, b-2), AIII, BII (b), BIII in accordance with GOST 13996–2019, ceramic bricks of grade M200 and higher in accordance with GOST 530–2012, and to produce ceramic tiles in accordance with GOST 56688–2015.
