Abstract (en)
[origin: EP1031543A1] The invention relates to blue coloured sodiocalcic glass. It contains 0.15 to 1.1 wt. % Fe2O3, has a redox that does not exceed 45 %, exhibits a dominant wavelength ( lambda D) in the range of 490 and 493 nm and a luminous transmission (TLA4) in addition to an excitation purity (P) satisfying the relation P>-0.3xTLA4+24.5. The inventive glass is particularly suitable for windscreens, side windows and rear-window defoggers in motor vehicles and glazing in buildings.
