GREY GLASS COMPOSITION

摘要

A grey glass composition employing in its colorant portion at least iron (Fe2O3/FeO), cerium, cobalt and selenium is provided. The glass allows high visible transmission, and satisfactory IR and UV absorption, while at the same time achieving desired grey color. In certain example embodiments, the colorant portion includes, or may consist essentially of: total iron (expressed as Fe2O3): 0.25 to 0.70 % cerium oxide: 0.01 to 1.0 % selenium: 0.0001 to 0.05 % cobalt oxide: 0.0001 to 0.05 % titanium oxide: 0 to 1.0 % glass redox: >= 0.30.
