Abstract
The present invention relates to a dark neutral green gray soda-lime glass composition comprising, as a colorant ingredient per 100 weight parts of a base glass composition, 1.4 to 2.5 weight parts of total FeO, 0.02 to 0.04 weight parts of CoO, 0.0001 to 0.004 weight parts of Se, 0.005 to 0.5 weight parts of MnO, and 0.05 to 1 weight parts of CeO. The glass composition of the present invention has a visible light transmittance (LT) of 15% or less, an ultraviolet ray transmittance (T) of 0 to 1%, and a solar transmittance (T) of 15% or less, measured for a reference thickness of 4 mm. As described above, the glass composition of the present invention is excellent in absorbing ultraviolet rays and solar heat, and therefore can be valuably used in privacy glass or a sunroof of a motor vehicle, or in glass used for construction.
