FIELD: varnish-and-paint industry. SUBSTANCE: silicate enamel suitable for coating architectural articles and household dishes contains, wt %: P₂O₅ 31.93-32.7, Al₂O₃ 24.17-24.76, B₂O₃ 10.94-11.20, K₂O 3.41-3.50, Na₂O 21.34-23.21, and TiO₂ 6.34-6.50. Firing temperature of enamel is 550 C, firing temperature interval 540-570 C, brilliance 65%, temperature resistance 20-250-20 C is 2-3 cycles, and adhesion force 72%. EFFECT: lowered firing temperature and prolonged lifetime due to increased chemical resistance of glass-enamel coating. 2 tbl
