| Zusammenfassung: | 232DDThe invention relates to a coloured soda-lime glass of blue hue, containing more than wt. % of MgO, more than wt. % of FeO, less than wt. % of FeO and less than wt. % of MnO, and presenting under Illuminant A and for a glass thickness of mm, a transmission factor (TLA) higher than %, a selectivity (SE) higher than and a dominant wavelength (λ) and a purity of excitation (P) such that they are located in the CIE chromaticity co-ordinate diagram inside a triangle whereof the apices are defined by the point representing the illuminant source C and the points whereof the co-ordinates (λ, P) are and respectively. Said glass is particularly suitable for motor vehicle side windows, rear windows and sun roof. |
