Abstract

See full text

A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer.
