<p>A soda lime silica glass having a colourant portion falling within one of the following combinations of ranges: Oxide Composition Fe2O3 2.1-4.0 weight % 2.1-4.0 weight % Co3O4 0-1000 ppm 200-800 ppm NiO 10-1000 ppm 50-800 ppm Se 0-100 ppm 10-70 ppm Fe2O3 2.3-3.8 weight % 2.1-4.0 weight % Co3O4 0-1000 ppm 0-1000 ppm NiO 10-1000 ppm 10-1000 ppm Se 0-100 ppm 50-100 ppm The glass has low solar heat transmittance and low visible light transmittance. It may be used as a solar control glass or a privacy glass, and is particularly suitable for rooflights, i.e. sunroofs and roof windows, for vehicles. The glass may be manufactured by the float glass process.</p> |
