Abstract:
The glass according to the invention has a soda-lime type composition to which are added colouring elements present in the following proportions by weight: Fe2O31.1 to 1.5% (total iron in the composition) Co150 to 200 ppm Cr2O325 to 100 ppm Se10 to 50 ppm MnOless than 600 ppm TiO2less than 0.1% the constituents of the composition, especially the coloured elements, being selected in such proportions that the luminous transmittance at a thickness of 4 mm, TLA4, is less than 20%, and the energetic transmittance, TE4 (Moon), is less than 20%.
