Abstract:
In embodiments, a glass includes from 45 mol % to 70 mol % SiO2; from 11.5 mol % to 25 mol % Al2O3; from 2 mol % to 20 mol % Li2O; from greater than 0 mol % to 10 mol % Na2O; from 9 mol % to 19 mol % MgO; from 4 mol % ZrO2; and from 0 mol % to 0.5 mol % TiO2. In other embodiments, a glass includes from 45 mol % to 70 mol % SiO2; from 4 mol % to 25 mol % Al2O3; from 5 mol % to 20 mol % Li2O; from 0.1 mol % to 10 mol % Na2O; from 6 mol % to 25 mol % MgO; from 0.1 mol % to 4 mol % ZrO2; from 0.1 mol % to 5 mol % K2O; and from 0.05 mol % to 0.5 mol % SnO2.
