<p>A soda-lime glass containing vanadium which can be produced by the float process with high UV absorption for wavelengths below 350 nm. The glass comprises 70 to 74 weight % SiO2, 0 to 2 weight % Al2O3, 0.1 weight % or less Fe2O3, 0 to 0.15 weight % TiO2, 7.5 to 10 weight % CaO, 3.5 to 5.4 weight % MgO, 12 to 15 weight % Na2O, 0 to 1 weight % K2O, 0 to 0.02 weight % BaO, 0.1 to 0.3 weight % SO3, 3 to 7 weight ppm CoO and 0.1 to 0.3 weight % V2O5.</p> |
