Abstract: A strengthened glass sheet product along with a process and an apparatus for strengthening a glass sheet are provided. The process comprises cooling the glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened glass sheets having improved breakage properties.

Abstract: A laminated glass article comprises a core layer comprising a core glass composition having an average core coefficient of thermal expansion (CTEcore) and a clad layer directly adjacent to the core layer and comprising a clad glass composition having an average clad coefficient of thermal expansion (CTEclad) that is less than the CTEcore such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer increases with increasing distance from the outer surface of the clad layer, transitions to a minimum tensile stress as a step-change at an interface region between the core layer and the clad layer, and a magnitude of the tensile stress increases continuously to a maximum tensile stress in the core layer. Other stress profiles, and methods of preparing laminated glass articles are also disclosed.
