摘要： A grey glass composition employing as its colorant portion at least iron (Fe2O3/FeO), cobalt and possibly erbium oxide (e.g., Er2O3) is provided. The glass enables high visible transmission, and satisfactory IR absorption, while at the same time achieving desired grey color. In certain example embodiments, the colorant portion includes: total iron (expressed as Fe2O3): =0.35. In other example embodiments, the glass may include higher total iron and/or a lower minimum redox.
