Abstract
A glass sheet having asymmetric chemical strengthening is disclosed and described. The examples described herein are directed to a cover glass for an electronic device and other glass components that may be used as enclosure elements or may form an enclosure. Within the glass component, localized compressive stress regions may be formed on opposite sides of the glass component, which may help arrest or redirect propagating cracks or defects in the glass. The opposing compressive stress regions may also help maintain the overall flatness of the component while increasing strength and/or impact resistance of the component.
