Abstract
A method of making a strengthened glass-based article includes compressing a cladding bonded to a glass at least in part by compacting the glass from a first density to a second density at least 10 mg/cm3 greater than the first density, where the compacting occurs when heating the glass to a temperature greater than 100° C. and below a softening temperature of the glass, whereby the compacted glass pulls the cladding into compression, thereby strengthening the glass-based article.

A method of making a strengthened glass-based article, comprising:
- rapidly cooling molten glass;
- bonding the glass to a cladding;
- heating the glass to a temperature greater than 100° C. and below a softening temperature of the glass, while bonded to the cladding, to increase density of the glass by at least 10 mg/cm3, and
- imparting compressive stress on the cladding during heating by compacting the glass bonded thereto, pulling the cladding into compression.
