    摘要: A glass composition employing as its colorant portion at least iron (total iron expressed as Fe2O3), erbium (e.g., Er2O3), and holmium (e.g., Ho2O3). The glass may be grey or otherwise colored in different embodiments. In certain example embodiments the colorant portion may include, by weight percentage: Ingredient wt. % total iron: 0.10-0.90% erbium oxide: 0.20-2.50% selenium:   0.0-0.0020% cobalt oxide:   0.0-0.0050% titanium oxide: 0.0-2.0% boron oxide: 0.0-2.0% holmium oxide: 0.10-1.60% thulium oxide: 0.0-2.0% ytterbium oxide: 0.0-3.0% lutetium oxide:  0.0-1.0%.
