Abstract:
An alkali aluminosilicate glass that is chemically strengthened and has a down-drawable composition. The glass has a melting temperature less than about 1650° C. and a liquidus viscosity of at least 130 kpoise and, in one embodiment, greater than 250 kpoise. The glass undergoes ion exchange at relatively low temperatures to a depth of at least 30 μm.
