摘要： Crystal lead-free glass suitable for man-made and machine-made utility glass especially of luxurious character with a higher refractive index, containing in % by weight from 50 to 65 of silicon dioxide SiO2, from 0.1 to 10 of aluminium oxide Al2O3, from 0.5 to 17 of zirconium dioxide ZrO2, from 10 to 22 of potassium K2O and/or sodium Na2O oxide, from 2 to 10 of calcium CaO and/or magnesium MgO oxide, the content of ferric oxide Fe2O3 being within the range from 0.01 to 0.025 % by weight. The properties of said glass are modified at least by one oxide from the group comprising barium BaO, zinc ZnO, boron B2O3 and lithium Li2O oxides. The further modifiers are either individually or in combination antimony trioxide Sb2O3, titanium dioxide TiO2 and stannic dioxide SnO2 within the range from a trace to 1 % by weight of antimony trioxide Sb2O3, titanium dioxide TiO2 and stannic dioxide SnO2.
