FIELD: chemistry; construction. ^ SUBSTANCE: present invention relates to the technology of silicates and glaze compositions for depositing on finish tiles and household ceramic objects. The glaze has the following components, in wt %: SiO2 56.0-62.0; Al2O3 22.0-24.0; TiO2, 1.0-2.0; CaO 1.0-2.0; Na2O 1.0-2.0; K2O 1.0-2.0; ZrO2 6.2-7.0; ZnO 1.0-2.0; B2O3, 3.0-4.0; CuO 0.2-0.3; PbO 0.2-0.3; BaO 0.2-0.3; CoO 0.2-0.3. The glaze has heat resistance of 320-330C. The glaze forms a smooth, even cyan-blue coating. ^ EFFECT: increased heat resistance of the glaze. ^ 1 tbl |
