FIELD: chemistry.
SUBSTANCE: invention concerns fritted glaze compositions used in production of tile and pottery utensils. The glaze includes SiO2, Al2O3, Fe2O3, TiO2, CaO, MgO, Na2O, K2O, ZrO2, B2O3, ZnO, CuO at the following component ratio, wt %: SiO2 - 54.0-58.0; Al2O3 - 3.0-5.0; Fe2O3 - 0.2-0.4; TiO2 - 4.0-6.0; CaO - 3.0-5.0; MgO - 1.0-2.0; Na2O - 1.0-2.0; K2O - 1.0-2.0; ZrO2 - 3.0-5.0; B2O3 - 16.0-18.0; ZnO - 3.0-5.0; CuO - 0.8-1.6.
EFFECT: increased heat resistance of glaze.
