FIELD: chemistry.
SUBSTANCE: glaze contains following components, wt %: SiO2 42.0-47.0; AI2O3 4.5-6.0; B2O3 9.5-13.0; CaO 12.5-15.5; MgO 4.0-6.0; PbO 9.0-12.0; CuO 1.5-2.5; MnO2 1.0-1.5; ZnO 4.0-6.0; ZrO2 1.0-1.5. Glaze frost resistance is 95-105 cycles. When glaze coating is fired in reducing medium, it acquires red-violet colour, when it is fired in oxidizing medium it acquires green-brown colour.
EFFECT: increase of glaze frost resistance.
