1. A method of manufacturing a strengthened glass article, comprising:
increasing by at least 20% compressive stress of a clad glass in a laminate comprising a core glass fused to the clad glass by heating up the laminate from below 100° C. to above 100° C. but below 600° C. and having the laminate above 100° C. but below 600° C. for longer than an hour, wherein the at least 20% increase is relative to a prior compressive stress in the clad present before the heating up,
wherein curves of coefficient of thermal expansion (y-axis) as a function of temperature (x-axis) of the core and clad glasses intersect one another above 100° C. but below 600° C.
