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: A glass composition includes from 60 mol % to 76 mol % SiO2; from 7 mol % to 16 mol % Al2O3; from 0 mol % to 12 mol % B2O3; and from 0 mol to 14 mol % Na2O. (R2O+RO)/Al2O3 in the glass composition may be greater than or equal to 1. A glass laminate article includes a core glass layer having a low temperature coefficient of thermal expansion (LTCTEcore) and a high temperature coefficient of thermal expansion (HTCTEcore): a clad glass layer laminated to a surface of the core glass layer, the clad glass layer having a low temperature coefficient of thermal expansion (LTCTEclad) and a high temperature coefficient of thermal expansion (HTCTEclad); and a thickness t.
