DARK GREEN SOLAR CONTROL GLASS COMPOSITION.

摘要

The invention relates to a dark green glass composition having a silica-sodic-calcic base and wherein the colorant compounds comprise, in weight percentage of the total amount: between 0.71 and 1.50% of iron expressed as Fe₂O₃; between 22 and 30% of a ferric-ferrous relation and between 0.15 and 0.50% of FeO, expressed as Fe₂O₃; between 0.10 and approximately 0.20% of SO₃ without affecting the refining properties of SO₃ and its ability to eliminate bubbles; between approximately 0 and approximately 1.0 in weight percentage of TiO₂; between approximately 0.0004 and approximately 0.03 in weight percentage of Cr2O3; and also between 0.0004 and 0.015 in weight percentage of CuO.
