Claim:
A blue colored, infrared and ultraviolet radiation absorbing glass substrate comprising a glass composition comprising a base glass portion and a glass colorant portion, wherein the base glass portion is a soda-lime-silica base portion, and the glass colorant portion is selected to provide a glass having chromaticity coordinates of a* in the range of −2 to −11 and b* in the range of −1 to −15, and a luminous transmittance of 35 to less than 70%, at a reference thickness of 0.160 inch (4.06 mm), wherein the colorant portion comprises: total iron, expressed as Fe 2 O 3 , in the range of 0.60 to 2.0 weight percent (wt %); CoO in the range of 30 to 250 parts per million (ppm); Er 2 O 3 in the range of 0.01 to 3 wt %; TiO 2 in the range of 0 to 0.9 wt %, Nd 2 O 3 in the range of 0 to 3 wt %, and Cr 2 O 3 in the range of 5 to 200 ppm, wherein the wt % and the ppm are based on the final glass composition.
