Abstract
A tinted glass composition and glass article including the same, the composition including: about 45 mol % to about 80 mol % SiO2; about 6 mol % to about 22 mol % Al2O3; 0 mol % to about 25 mol % B2O3; about 7 mol % to about 25 mol % of at least one alkaline earth oxide selected from MgO, CaO, SrO, BaO, and combinations thereof; about 0.5 mol % to about 20 mol % CuO; 0 mol % to about 6 mol % SnO2, SnO, or a combination thereof; 0 mol % to about 1.0 mol % C; 0 mol % to about 5 mol % La2O3; and 0 mol % to about 10 mol % PbO, and that is substantially free of alkali metal.
