Zusammenfassung:	FIELD: ceramic and building industry. ^ SUBSTANCE: invention relates to the glaze composite used in manufacturing facade plates and glazed brick. Glaze comprises components taken in the following ratio, wt.-%: SiO2, 46.0-52.0; Al2O3, 7.0-14.0; B2O3, 12.0-14.0; MgO, 1.5-2.5; Na2O, 6.0-7.5; K2O, 5.0-6.0; SrO, 8.0-12.0. Glaze can comprise additionally pigments, for example, Co3O4 in the amount 1.2-2.0 wt.-% or CuO in the amount 2.5-3.5 wt.-%. Glaze shows high fluidity coefficient and good covering power. Invention provides preparing strontium-magnesium-boron glaze showing relatively low roasting temperature (700-750°C), high resistance to cold and thermal stability that allows its using for manufacturing glazed bricks that endure large temperature drops and reducing its cost also. ^ EFFECT: improved and valuable properties of glaze. ^ 3 cl, 1 tbl, 4 ex
