    摘要： A glass plate, with a thickness θ of 1.0 mm or more, having first and second main surfaces and end surfaces, includes 1 to 80 weight ppm of iron in terms of Fe2O3 with 0.1 to 10.0 weight ppm of Fe2+; and 0.1 to 10.0 weight ppm of Ni, Mn, Cr, Co and V in total. In a sample with a size of 50 mm×50 mm×θ obtained from the glass plate, and an arithmetic average roughness of the main surfaces and first and second cut surfaces being 0.1 μm or less, a first average absorbance coefficient for a wavelength of 400 to 700 nm measured on the first main surface in a normal direction is 0.009 or less, and a ratio of a second average absorbance coefficient measured on the first cut surface, to the first absorbance coefficient is 1.3 or less.

    摘要： 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.

    摘要： The present invention provides a high-transparency glass having a high fining action at a low temperature and capable of achieving redox lowering more than before. The present invention relates to a glass containing 1 to 500 ppm of a total iron oxide (t-Fe2O3) in terms of Fe2O3, having a redox ([divalent iron (Fe2+) in terms of Fe2O3]/[total (Fe2++Fe3+) of divalent iron (Fe2+) and trivalent iron (Fe3+) in terms of Fe2O3]) of 0% or more and 25% or less, containing, as expressed by mass percentage based on oxides, 50 to 81% of SiO2, 1 to 20% of Al2O3, 0 to 5% of B2O3, 5 to 20% of Li2O+Na2O+K2O, and 5 to 27% of MgO+CaO+SrO+BaO, and having a bubble disappearance-starting temperature (TD) of 1485° C. or lower.

    摘要： A soda lime glass plate has, on the basis of oxides, a total sulfur content in terms of SO3 of 0.001 to 0.2% in mass %, a total iron content in terms of Fe2O3 of 0.15 to 0.4% in mass %, and a total tin content in terms of SnO2 of 0.02 to 1% in mass %, and has a mass proportion of a divalent iron in terms of Fe2O3 in the total iron in terms of Fe2O3 of 45 to 70%. The soda lime glass plate has, as a conversion value for a 3.85 mm-thickness glass plate, a visible light transmittance Tv_A of 70% or more, a total solar transmittance Tts of 63.7% or less, and c* in the L*a*b* color space of 4 or less.
