Abstract
A colored glass article includes from 40 mol % to 70 mol % SiO2; from 8 mol % to 20 mol % Al2O3; from 1 mol % to 10 mol % B2O3; from 1 mol % to 20 mol % Li2O; from 1 mol % to 15 mol % Na2O; from 0 mol % to 8 mol % MgO; from 0 mol % to 5 mol % ZnO; and from 0.0005 mol % to 1 mol % Au. MgO+ZnO is from 0.1 mol % to 6 mol %.
