A neutral, generally green colored, infrared energy and ultraviolet radiatio n absorbing glass composition comprises conventional soda-limo-silica float glass ingredients, a relatively high concentration of moderately reduced iron, and titanium oxide(s). The resultant glass exhibits an Illuminant A visible light transmittance of at least 70 %, a total solar energy transmittance not greater than about 46 %, and an ultraviolet radiation transmittance not greater than approximately 38 %, at selected glass thicknesses in the range of 3mm to 5mm. The titanium oxide(s) as well as at least a portion of the iron in the glass is provided by the inclusion of the mineral ilmenite in the glass batch formulation.
