Abstract
A colorant for a high redox glass composition comprising: total iron (Fe2O3) 0 to 1.1 weight percent; and from 0.0001 to 0.15 weight percent of at least one of the following: Cu nanostructures, Au nanostructures, or Ag nanostructures, wherein the weight percents are based on the total weight of the glass composition. The colorant of the invention can be used to make glass compositions having various colors.
