Colored glass plate and method for its production
Abstract:
To provide a colored glass plate which, despite the content of expensive cerium controlled to be low, simultaneously satisfies low solar transmittance, high visible light transmittance and low UV transmittance, while transmitted light has a green color tone. The colored glass plate comprises, as represented by mass percentage based on oxides, SiO2: from 65 to 75%, Al2O3: from 0 to 6%, MgO: from 0 to 6%, CaO: from 5 to 15%, total iron calculated as Fe2O3: from 0.3 to 1.2%, total titanium calculated as TiO2: from 0.2 to 1.1%, total vanadium calculated as V2O5: from 0.02 to 0.3%, and total cerium calculated as CeO2: from 0.01 to 0.5%, and contains substantially no cobalt, chromium or manganese.
