摘要

FIELD: metallurgy.SUBSTANCE: proposed composition contains the following substances, in wt %: soda - 19.0-21.0, borax - 5.0-7.0, cryolite - 5.0-7.0, perlite and/or obsidian - 67.0-69.0. Glass melting is performed at 1260-1300°C. Melt is poured in metal moulds made from refractory steel. Glass articles are subjected to annealing and machining.EFFECT: lower temperature glass melting.1 tbl
