FIELD: glass.
SUBSTANCE: invention relates to the industry of making artificial porous glass gravel. Artificial porous glass gravel as raw materials contains scrap glass, glycerin, soluble glass, thermal power plant slag in the following proportions, wt%: thermal power plant slag 25-35; scrap glass 65-55; glycerin 8; soluble glass 2.
EFFECT: technical result consists in reduction of foaming temperature up to 850-870 °C, increase in number of thermal power plant slag in the composition of artificial porous glass gravel.
