FIELD: chemistry.
SUBSTANCE: invention relates to silicate processes and, particularly, to fritted glaze compositions that can be efficiently used in production of facing tiles. The glaze contains, percent by mass: SiO2 40.0-45.0; Al2O3 3.0-5.0; Na2O 1.0-2.0; K2O 1.0-2.0; CaO 3.0-5.0; B2O3 35.0-38.0; MgO 3.0-5.0; CuO 0.5-1.5; PbO 0.5-1.5; TiO2 3.0-5.0.
EFFECT: increase in glaze frost resistance.
