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)2*(−7.3628)+(Al2O3−2.863)*(K2O−0.520)*(321.5)+(B2O3−9.668)*(K2O−0.520)*(−39.74)))/t.
