Brown decorative glass made mainly from liquid blast furnace slag and production method thereof

The invention discloses brown decorative glass made mainly from liquid blast furnace slag, made mainly from the liquid blast furnace slag and auxiliaries; glass melt formed by mixing the liquid blast furnace slag and the auxiliaries is mainly composed of, by weight, 45-65% of SiO2, 5-8% of Al2O3, 10-20% of CaO, 3-5% of MgO3, 4-8% of BaO, 3-6% of Na2O, 2-6% of ZnO, 0-3% of Sb2O3, 1-5% of Fe2O3, 0-3% of TiO2, and 0-3% of MnO2. The liquid blast furnace slag is used as a main material to produce the brown decorative glass, the produced brown decorative glass has uniform color, good chemical stability and high gloss and has a density range of 2.50-2.70 g/cm and a three-point breaking strength range of 60-90 MPa; the liquid blast furnace slag is used to produce the brown decorative glass, components and sensible heat thereof are made full use, high-added-value products can be produced with the high blast furnace slag, and energy conservation and emission reduction can be achieved.
