Abstract
The invention concerns a soda-lime glass. Said colored glass contains at least 5 parts per million of Co by weight and 0.5 to 0.9 wt. % FeOoxide. The amount of ferrous iron by weight of Featoms 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.
