building industry. SUBSTANCE: decorative-facing material comprises one layer manufactured by method of rolling pyroplastic glass body with viscosity of (103-105) Pa.s and surface tension value of 0.2-0.3 n.m prepared using granule powder technology which involves heat treating crushed glasses. Material of infinite shapes having thickness of from 4 to 25 mm is molded on shape rolling machines. Crystallization and annealing over, the resulting shape is cut into final products. EFFECT: greater process efficiency. 4 cl, 10 dwg, 3 ex
