Patent ID: 8785338

Claim:
A glass with low solar transmittance, comprising: a basic composition of soda-lime-silica glass, and as coloring components 0.70-1.70 mass % of Fe 2 O 3 (total iron in terms of ferric iron), 0.15-0.45 mass % of FeO (ferrous iron), 0-0.8 mass % of TiO 2 , 100-350 ppm by mass of CoO, 1-50 ppm by mass of Se, 100-700 ppm by mass of Cr 2 O 3 , and 3-150 ppm by mass of MnO, and having a ratio (Fe 2+ /Fe 3+ ) of ferrous iron to ferric iron of 0.20-0.80, a solar transmittance of 30% or less, a visible light transmittance of 5-30% and an ultraviolet transmittance of 30% or less in terms of 4 mm thickness by a measurement using an illuminant A, a ratio of a visible light transmittance to a solar transmittance of 0.50 or greater and a ratio of a ultraviolet transmittance to the solar transmittance of 1.25 or less.
