manufacture of decorative facing materials. SUBSTANCE: blend comprising main glass- forming components also comprises mixture of iron-containing stock, metallic aluminium and sodium sulfate. In this case, Σ(Al+Na2SO4) = 12-24 (kg/t of glass body) and A/Na2SO4 ratio is 1.8-2, and content of iron-containing based on iron powder is 1-4 kg/t of glass body. In order to increase intensity of color hue, blend further comprises metallic selenium (Se) and at heat one component from group consisting of CoO and NiO in amount of Σ(Se+MeOn= 0,01-0,2 (kg/t of glass body) at Se/MeOn ratio of 0.5-3. EFFECT: more efficient manufacturing method. 3 cl, 3 ex |
