Abstract
The present invention is a blue soda-lime-silica 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: 0.3 to 0.8 wt. % total iron oxide as Fe O wherein the ratio of FeO/total Fe as Fe O is 0.35 to 0.62; 0.05 to 0.5 wt. % manganese compound as MnO , 0 to 0.30 wt. % titanium oxide as TiO ; and 0 to 0.8 wt. % cerium oxide as CeO . The colored glass has the following spectral properties at 4.0 mm. thickness: 65 to 81% light transmittance using Illuminant A (LTA) and using Illuminant C has a dominant wavelength of 488 to 494 nanometers with an excitation purity of 4 to 11%.
