  • Patent number: 5582455
    Abstract: The invention concerns compositions of coloured glasses intended for the manufacture of glazing panes suitable for mounting in an automobile vehicle. The panes are of silico-sodo-calcic glasses having a total energy transmission factor (T.sub.E) less than the light transmission factor under illuminant A (TL.sub.A), the factor T.sub.E being from 10 to 48% and the factor TL.sub.A from 20 to 60% for a thickness of 3.85 nm; these glasses comprise (in % by weight), as colouring agents, from 0.45 to 2.5% of Fe.sub.2 O.sub.3 (total iron), from 0.001 to 0.02% of CoO, from 0 to 0.0025% of Se and from 0 to 0.1% of Cr.sub.2 O.sub.3.

  • Patent number: RE37998
    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 Fe2O3 and 0 to 0.05 % cobalt oxide, with the cobalt oxide exceeding about 0.02% when the Fe2O3 is below about 2% and, optionally, selenium and chromium oxide, whereby the sum of the CoO+Se+Cr2O3 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.
