<p>The invention concerns a soda-lime glass. Said coloured glass contains at least 5 parts per million of Co by weight and 0.5 to 0.9 wt. % of Fe2O3 oxide. The amount of ferrous iron by weight of Fe2+ atoms relative to the total weight of iron atoms present in the glass ranges between 25 and 45 %. Said glass further comprises chromium and/or vanadium. The glass has a light transmission factor TLA4 ranging between 10 and 50 % and an energy transmission wavelength less than 491 nm. Said glass is particularly suited for producing blue-tinted glazing for motor vehicles.</p> |
