FIELD: production of colored decorative facing materials based on granulated glasses and crystalline fillers. SUBSTANCE: method for production decorative facing slabs consists in that decorative layer of slab material is formed from mixture of granules of base glass with ceramic pigment mixed with glass powder with fraction of less than 0.1 mm in ratio of 1:(5-10) and 10-% solution of water glass at definite empirical ratio of components. To produce the material of gray-black color introduced into initial mixture of components is one oxide of metal of the group including NiO, MnO, CuO, and the main color is used in the form of black pigment of the system CuO-FeO-CoO at definite amounts of components determined empirically. EFFECT: higher efficiency. 2 cl, 4 tbl |
