Abstract: A high-strength alkali-aluminosilicate glass, characterized by excellent meltability, fineability. and processibility, exhibits the following formula: SiO2 60.5 to 69.0 weight percent Al2O3 7.0 to 11.8 weight percent B2O3 0 to 4.0 weight percent MgO 2.0 to 8.5 weight percent CaO 0 to 4.0 weight percent ZnO 0 to 5.0 weight percent ZrO2 0 to 3.0 weight percent Na2O 15.0 to 17.5 weight percent K2O 0 to 2.7 weight percent Li2O 0 to 2.0 weight percent and from 0 to 1.5 weight percent of a fining agents such as As2O3, Sb2O3 CeO2, SnO2, Cl?, F?, (SO4)2? and combinations thereof. The glass allows for adequate conditions for an alkali ion exchange treatment in a short time period (4 to 8 hours) and can also be produced according to the established, continuous, vertically downward directed drawing process such as the overflow down-draw method or the fusion method, the die slot or the slot down-draw method, or combinations thereof.
