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.
