COLOURED SODA-LIME GLASS

摘要

The present invention relates to a coloured soda-lime glass which comprises iron in a quantity which, expressed in weight of the oxide Fe2O3 in relation to the total weight of glass, is greater than or equal to 0.5, and less than or equal to 1.0% (quantity of total iron), a ratio of Fe<2+>/total Fe (redox ratio) in the range of between 20 and 65%, cerium in a quantity which, expressed in weight of CeO2 in relation to the total weight of glass, is greater than or equal to 0.1%, and titanium in a quantity which, expressed in weight of TiO2 in relation to the total weight of glass, is greater than or equal to 0% and less than 0.2%. This glass has a light transmission (TLA4) in the range of between 15 and 55%, a total transmission in the ultraviolet (TUV4) of less than or equal to 30%, and a dominant wavelength in transmission (lambdaD) of less than or equal to 491 nm. This glass can be used, for example, as side glazing, rear-view window, roof glazing or opening roof of a motor vehicle.
