Beschreibung
Zusammenfassung:	An infrared and ultraviolet radiation absorbing glass suitable for use in building and vehicle windows, which comprises, on a weight basis, 68-72% of SiO2, 1.6-3.0% of Al2O3, 8.5-11.0% of CaO, 2.0-4.2% of MgO, 12.0-16.0% of Na2O, 0.5-3.0% of K2O, 0.03-0.30% of SO3, 0.58-0.80% of total iron expressed as Fe2O3, 0.1-0.7% of CeO2, 0.1-0.4% of TiO2 and 5-350 ppm of MnO. In the glass the ratio of ferrous iron to ferric iron is in the range from 0.50 to 0.70. The glass has a greenish tint and is well balanced in visible light transmittance, infrared radiation absorption and ultraviolet radiation absorption, and a sheet of the glass can be easily tempered by a conventional method.
