Abstract:
In a soda lime glass, a content of total iron calculated as Fe2O3, expressed in mass % on an oxide basis, is 0.25 to 1%, a mass proportion of divalent iron calculated as Fe2O3 in the total iron calculated as Fe2O3 is 30 to 50%, a content of total sulfur calculated as SO3, expressed in mass % on an oxide basis, is 0.003 to 0.1%, and a content of Se is 3 mass ppm or more. In the soda lime glass, visible light transmittance Tv_D65 is 30 to 55% calculated as 6 mm thickness of a glass sheet, solar direct transmittance Te is 20 to 40% calculate as 6 mm thickness of a glass sheet, and excitation purity Pe is 8.0% or less calculated as 6 mm thickness of a glass sheet.
