Abstract:
A method for generating various stress profiles for chemically strengthened glass. An alkali aluminosilicate glass is brought into contact with an ion exchange media such as, for example, a molten salt bath containing an alkali metal cation that is larger than an alkali metal cation in the glass. The ion exchange is carried out at temperatures greater than about 420° C. and at least about 30° C. below the anneal point of the glass.
