Abstract
A laminated glass article includes a glass core layer having a core modulus Ecore and a glass cladding layer adjacent to the core layer and having a cladding modulus Eclad. Eclad can be at least 5 GPa less than Ecore. A modulus ratio Ecore/Eclad can be at least 1.08. The cladding layer can have a compressive stress resulting from a coefficient of thermal expansion (CTE) contrast between the core layer and the cladding layer and/or subjecting the laminated glass article to an ion exchange treatment to form an ion exchanged region at an outer surface of the cladding layer.
