Abstract: A method of manufacturing a strengthened glass article includes forming a glass-to-glass laminate by fusing clad and core glasses, where the clad has greater high-temperature coefficient of thermal expansion (HTCTE) than the core but a lesser low-temperature coefficient of thermal expansion (LTCTE). The method includes cooling the laminate to impart stresses through contraction mismatch between the clad and core, where stresses in the laminate from HTCTE differences at least partially offset stresses in the laminate from LTCTE. After the cooling, the method includes modifying geometry of the laminate, then relaxing at least some of the stresses in the glass-to-glass laminate from differences in the HTCTE.

Abstract: Glass-based articles are provided that exhibit improved drop performance. The relationship between properties attributable to the glass composition and stress profile of the glass-based articles are provided that indicate improved drop performance.
