ABSTRACT:
An infrared and ultraviolet radiation absorbing glass suitable for use in building and vehicle windows, which comprises, on a weight basis, 68.0-73.0% SiO.sub.2, 0.1-3.0% Al.sub.2 O.sub.3, 7.0-11.0% CaO, 2.0-4.2% MgO, 12.0-16.0% Na.sub.2 O, 0.5-3.0% K.sub.2 O, 0.02-0.30% SO.sub.3, 0.30-0.90% total iron expressed as Fe.sub.2 O.sub.3, 0.10-0.80% CeO.sub.2, 0-1.0% TiO.sub.2, 0-0.5% ZnO, 0-0.1% MnO and 0-0.01% CoO. In the glass the ratio of ferrous iron to ferric iron is from 0.8 to 2.5. The glass has a bluish tint and is well balanced in visible light transmittance, infrared radiation absorption and ultraviolet radiation absorption, and a sheet of the glass can easily be tempered by a conventional method. In producing this glass, it is favorable to use cullet of a frit glass in which the ratio of ferrous iron to ferric iron is from 2.0 to 5.0 as a part of a batch of glass compostion to be melted.
