FIELD: reworking of wastes of glass industry; regeneration of fluoride glass and waste of its process; production of optically transparent glass.
SUBSTANCE: proposed method includes dissolving of wastes in ammonium bifluoride at their mass ratio of 1:3-5, evaporation of excessive bifluoride and obtaining powder-like product which is then treated with gaseous fluorine in the amount of 18-20 g per 100 g of powder for obtaining charge used for making glass.
EFFECT: enhanced efficiency.
