Abstract
The results of a study of the chemical and mineralogical composition of hematite rock from the Kyzyltash deposit for the production of a reddish ceramic pigment that is thermally and chemically stable at high temperatures are presented. The changes in the color characteristics of the synthesized pigment depending on the firing temperature in the range of 1000-1100°C are studied. It has been established that this domestic raw material can be used to produce ceramic pigments for coloring ceramic, porcelain, earthenware, and glass products for household, construction, and technical purposes.
