Abstract
A glass composition comprises: 50.0 mol % to 70.0 mol % SiO; 10.0 mol % to 25.0 mol % AlO; 0.0 mol % to 5.0 mol % PO; 0.0 mol % to 10.0 mol % BO; 5.0 mol % to 15.0 mol % LiO; 1.0 mol % to 15.0 mol % NaO; and 0.0 mol % to 1.0 mol % KO. The sum of all alkali oxides, RO, present in the glass composition may be in the range from greater than or equal to 11.0 mol % to less than or equal to 23.0 mol %. The sum of AlOand RO present in the glass composition may be in the range from greater than or equal to 26.0 mol % to less than or equal to 40.0 mol %. The glass composition may satisfy the relationship −0.1≤(AlO—(RO+RO))/LiO≤0.3.
