FIELD: chemistry.
SUBSTANCE: invention relates to production of foamed glass. Powdered mixture based on crushed glass and mineral substance - talc, is prepared, with the following ratio of components in wt %: talc 2-8, glass - the balance. The mixture is heated in a metal mould at foaming temperature of 720-780°C, followed by annealing.
EFFECT: simple method of producing foamed glass, low cost thereof, high strength, water absorption and frost resistance of the obtained material.
