摘要: A glass composition has a base and colorant. The of the is 68 to 75% SiO2, 10 18 wt. % Na2O, 5 15 CaO, 0 MgO, Al2O3, K2O, where CaO+MgO 6 Na2O+K2O 20 provided. colorants comprises 0.4 0.6 Fe2O3, 0.18 0.28 FeO, 0.05 0.3 MnO2, 8 ppm Cobalt. redox ratio weight FeO total iron in range about 0.40 0.58. colored an aqua color with dominant wavelength 489.2 nm +/−1.2 nm, excitation purity 7% +/−1%, infrared transmittance 16% 29% at 4.0 mm thickness.
