Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

Abstract: A glass article may include SiO2, Al2O3, B2O3, at least one alkali oxide, and at least one alkaline earth oxide. The glass article may be capable of being strengthened by ion exchange. The glass article has a thickness t. The concentration(s) of the constituent components of the glass may be such that: 13≤0.0308543*(188.5+((23.84*Al2O3)+(−16.97*B2O3)+(69.10*Na2O)+(−213.3*K2O))+((Na2O−7.274)*(−7.3628)+(Al2O3−2.863)*(K2O−0.520)*(321.5)+(B2O3−9.668)*(K2O−0.520)*(−39.74)))/t.

Abstract: A method of manufacturing a strengthened glass article comprises soaking a glass article in a bath comprising molten salt. The molten salt comprises alkali metal ions. During the soaking, the alkali metal ions of the salt are exchanged for smaller alkali metal ions of glass of the glass article and impart a compressive stress in the glass article in an ion-exchanged portion thereof at or near a surface thereof. The glass of the glass article has a strain point temperature of at least 625° C., corresponding to glass viscosity of 1014.68 poise. The temperature of the bath is at least 70° C. below the strain point temperature of the glass of the glass article.
