To provide a low light transmittance gray glass formed from a composition.SOLUTION: A low light transmittance gray glass formed from a composition includes colorants. The colorants include 1.8 wt.% to 2.3 wt.% of Fe2O3, 0.28 wt.% to 1.2 wt.% of FeO, 0.030 wt.% to 0.040 wt.% of Co3O4, 0.0020 wt.% to 0.010 wt.% of Se, 0.00050 wt.% to 0.050 wt.% of CuO, and 0.01 wt.% to 1 wt.% of TiO2. The glass has a visible light transmittance (TLA) of less than 15%, a direct solar transmittance (TDS) of less than 14%, an infrared transmittance (TIR) of less than 14%, an ultraviolet transmittance (TUV) of less than 8%, and a total solar transmittance (TTS) of less than 38%.SELECTED DRAWING: None
