摘要：
A grey glass composition employing as its colorant portion at least iron (Fe 2 O 3 /FeO), cobalt and possibly erbium oxide (e.g., Er 2 O 3 ) 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 Fe 2 O 3 ): erbium oxide (e.g., Er 2 O 3 ): 0 to 0.3% selenium (Se): cobalt oxide (e.g., Co 3 O 4 ): 5 to 60 ppm glass redox: >=0.35. In other example embodiments, the glass may include higher total iron and/or a lower minimum redox.
