This invention relates to the manufacture of stone products. In order to reduce the melting temperature of the charge, reduce the water absorption of products and obtain a material that simulates the pattern of natural stone - malachite, stone casting contains the following components, wt%: SiO 50.00-62.00; A1.0 5.00-12.00; FeO 0.10-1.50; 0.10-1.50; CaO 12.00-20.00; MgO 1.00-5.00; Na, 7.00- 13.00; 0.10-3.00; 0.50-2.00; Lijb 0.0f-5.00; Cl 0.01-0.10 and Ag 0.01-0.02. Stone casting has: a density of 2950-2980 kg / m, an apparent porosity of 0.011-0.051%, a water absorption of 0.003-0.009%, and a chemical resistance to water of 0.01%. 2 tab. i (L QO (4 01 |
