Abstract
A glass composition includes: 50 mol % to 69 mol % SiO; 12.5 mol % to 25 mol % AlO; 0 mol % to 8 mol % BO; greater than 0 mol % to 4 mol % CaO; greater than 0 mol % to 17.5 mol % MgO; 0.5 mol % to 8 mol % NaO; 0 mol % to 2.5 mol % LaO; and greater than 8 mol % to 18 mol % LiO, wherein (LiO+NaO+MgO)/AlOis from 0.9 to less than 1.3; and AlO+MgO+LiO+ZrO+LaO+YOis from greater than 23 mol % to less than 50 mol %. The glass composition may be characterized by at least one of the following: a Kvalue measured by a chevron short bar method of at least 0.75; and a Kvalue measured by a double torsion method of at least 0.8. The glass composition is chemically strengthenable. The glass composition may be used in a glass article or a consumer electronic product.
