The areas of use of glass domestic waste in the building materials industry are considered. The possibility of obtaining a facing and decorative material-smalt based on colored container and high-quality glass is considered. An innovative technology has been developed for the production of smalt based on finely ground powders of colored container glass using 20%, 40% and 60% liquid glass as a humidifier. The dependences of the influence of various concentrations of aqueous solutions of liquid glass on the degree of compaction of smalt are established. It is shown that the addition of aqueous solutions of liquid glass to the glass powder before pressing reduces the firing temperature from 775 to 725 ° C. the influence of different concentrations of aqueous solution of liquid glass in the initial charges on the chemical composition of the smalt is investigated. The elemental composition of smalt is studied using the x-ray fluorescence method. The microstructure of smalt made from a mixture with an optimum content of 40% aqueous solution of water glass is investigated. The effect of various concentrations of liquid glass on the microhardness of smalt is provided. It is shown that when the content of 40% liquid glass in an aqueous solution, the microhardness reaches maximum values.
