FIELD: chemistry.
SUBSTANCE: invention concerns silicate technology and fritted glaze compositions for glazing facing tile. The glaze includes SiO2, Al2O3, CaO, MgO, ZrO2, B2O3, ZnO, BaO, Na2O, TiO2, PbO, As2O3 in the following component ratio, in mass %: SiO2 - 56.5-62.5; Al2O3 - 3.5-5.0; CaO - 6.0-9.0; MgO - 1.0-2.0; ZrO2 - 6.0-9.0; B2O3 - 8.0-12.0; ZnO - 1.5-3.0; BaO - 2.0-3.0; Na2O - 2.0-3.0; TiO2 - 0.3-0.5; PbO - 1.5-2.4; As2O3 - 0.1-0.2.
EFFECT: improved frost resistance of glaze.
