Patent ID: 8318054

Claim:
A dark green colored glass comprising a base glass composition and a modifiying portion, in weight, consisting essentially of: from 0.71 to 1.50% of total iron expressed as Fe 2 O 3 ; from 22 to 30% of Fe 2+ and from 0.15 to 0.50% of FeO, expressed as Fe 2 O 3 ; from about 0.10 to about 0.20% of SO 3 ; from about 0 to about of 1.0% TiO 2 ; from about 0.0004 to about of 0.03% Cr 2 O 3 ; and from about 0.0004 to about 0.015% CuO, wherein the glass composition having an illuminant “A” light transmission (TLA) greater than 65%, a total solar energy transmittance (TS) of less than or equal to 60%; a solar ultraviolet transmittance (TUV) of less than 46%; a dominant wavelength from 490 nm to 600, and an excitation purity of less than 7%.
