ABSTRACT:
The invention relates to a colored glass composition for producing glazings for use, e.g., as automobile sunroofs. The colored glass according to the invention is a soda-lime-silica glass comprising, as coloring agents, 1.4 to 4% iron oxide expressed as Fe.sub.2 O.sub.3 and 0 to 0.05% cobalt oxide, with the cobalt oxide exceeding about 0.02% when the Fe.sub.2 O.sub.3 is below about 2% and, optionally, selenium and chromium oxide, whereby the sum of the CoO+Se+Cr.sub.2 O.sub.3 is preferably less than about 0.24% by weight. The glass of the invention has a total light transmission factor under illuminant A equal to or below approximately 20% and a total energy transmission factor equal to or below approximately 12% for a thickness of 3.85 mm.
