Original Abstract Submitted
Disclosed herein are embodiments of a borosilicate glass composition comprising BOin an amount greater than or equal to 11 mol % and less than or equal to 16 mol %; AlOin an amount greater than or equal to 2 mol % and less than or equal to 5 mol %; one or more alkali metal oxides; one or more alkaline earth metal oxides; a total amount of NaO, KO, MgO, and CaO that is greater than or equal to 7.0 mol %°. Amounts of SiO, BO, the one or more alkali metal oxides, AlO, and the one or more alkaline earth metal oxides, satisfy: (RO+R′O)≥AlO, and 0.80<(1−[(2RO+2R′O)/(SiO+2AlO+2BO)])<0.93, where RO and R′O are sums sum of the concentrations of the one or more alkali metal oxides and the one or more alkaline earth metal oxides, respectively.
