FIELD: chemistry.
SUBSTANCE: invention relates to compositions of charges for obtaining coloured in mass lead glass and can be used for manufacturing products of industrial and decorative and artistic purpose. Charge for obtaining lead glass is produced by mixing wastes of dextrinated lead azide production, which contains more than 99% of lead carbonate, with silica, soda, potash, potassium nitrate and zinc oxide with the following component ratio, wt %: quartz sand - 52.3; soda - 8.3; potash - 13.3; zinc oxide - 2.9; wastes of dextrinated lead azide - 22.8.
EFFECT: improvement of the environment ecology and cheapening of lead glass production due to utilisation of wastes of dextrinated lead azide production.
