FIELD: chemistry.
SUBSTANCE: invention relates to fritted glaze compositions used for production of facing tiles. The glaze contains SiO2, Al2O3, CaO, MgO, K2O, Na2O, B2O3, MnO2 and, additionally, PbO and SrO in the following ratio of components, percent by mass: SiO2 - 40-45, Al2O3 - 10-15, CaO - 3-5, MgO - 3-5, K2O - 1-2, Na2O - 1-2, B2O3 - 15-20, MnO2 - 1-2, PbO 3-5, SrO 8-14.
EFFECT: increase in glaze frost resistance.
