Abstract

A glass composition includes: greater than or equal to 55 mol % and less than or equal to 70 mol % SiO; greater than or equal to 14 mol % and less than or equal to 25 mol % AlO; greater than or equal to 0 mol % BO; greater than or equal to 0 mol % PO; greater than or equal to 0 mol % and less than or equal to 10 mol % LiO; greater than or equal to 6.5 mol % and less than or equal to 20 mol % NaO; greater than or equal to 0 mol % KO; greater than or equal to 0.1 mol % and less than or equal to 4.5 mol % MgO; greater than or equal to 0 mol % CaO; and greater than or equal to 0 mol % SrO. The sum of LiO, NaO, and KO in the glass composition may be greater than or equal to 6.5 mol % and less than or equal to 22 mol %. The glass composition may satisfy the relationship AlO*(2.94)+BO*(−0.58)+PO*(−3.87)+LiO*(5.01)+NaO*(1.89)+KO*(−2.03) is greater than 100.
