FIELD: chemistry.
SUBSTANCE: invention relates to fritted glaze compositions used for production of facing tile. The glaze contains SiO2, Al2O3, TiO2, CaO, MgO, Na2O, K2O, P2O5 and, additionally, ZrO2, B2O3, BaO in the following ratio of components, percent by mass: SiO2 - 54.0-62.0, Al2O3 - 5.0-15.0, TiO2 - 1.0-2.0, CaO - 10.0-15.0, MgO - 1.0-2.0, Na2O - 1.0-2.0, K2O - 1.0-2.0, P2O5 - 1.0-2.0, ZrO2 - 1.0-2.0, B2O3 - 7.0-11.0, BaO - 1.0-2.0.
EFFECT: increase in glaze frost resistance.
