Abstract
The present invention is a bronze and gray glass composition. The composition comprises 68 to 75% SiO , 10 to 18% Na O, 5 to 15% CaO, 0 to 10% MgO, 0 to 5% Al O , and 0 to 5% K O, where CaO+MgO is 6 to 15% and Na O+K O is 10 to 20%, and colorants comprising: 0.22 to 0.39 wt. % total iron as Fe O wherein the ratio of FeO/total Fe as Fe O is 0.35 to 0.64; 0.1 to 0.5 wt. % manganese compound as MnO ; 0 to 1.2 wt. % cerium oxide as CeO ; and 2 to 10 ppm selenium, and 0 to 20 ppm cobalt as cobalt oxide. The colored glass has the following spectral properties at 4.0 mm. thickness: 65 to 78% light transmittance using Illuminant A (LTA) and using Illuminant C has a dominant wavelength of 493 to 577 nanometers with an excitation purity up to 7%.
