Abstract
Glass compositions containing, expressed in percentages by weight, from 0.75 to 1.4% total iron expressed in the form Fe.sub.2 O.sub.3, from 0.25 to 0.32% ferrous iron in the form of FeO and which has, and at a thickness of between approximately 3 and 3.3 millimeters, exibit a total light transmission factor under illuminent A (TL.sub.A) of at least 70%, a total energy transmission factor (T.sub.E) less than approximately 46% and a transmission factor for ultraviolet radiation (T.sub.UV) less than approximately 25%, and are suitable for the production of windows or panes for use in the architectural field or in automobile and industrial vehicles.
