Abstract: Apparatus, systems and methods for improving strength of a thin glass member for an electronic device are disclosed. In one embodiment, the glass member can have improved strength characteristics in accordance with a predetermined stress profile. The predetermined stress profile can be formed through multiple stages of chemical strengthening. The stages can, for example, have a first ion exchange stage where larger ions are exchanged into the glass member, and a second ion exchange stage where some of the larger ions are exchanged out from the glass member. In one embodiment, the glass member can pertain to a glass cover for a housing for an electronic device. The glass cover can be provided over or integrated with a display.
