Abstract
Latent colorant material compositions, soda-lime-silica glass compositions, and related methods of manufacturing color-strikable glass containers. The latent colorant material compositions may be introduced into a plurality of base glass compositions having redox numbers in the range of −40 to +20 to produce color-strikable glass compositions and color-strikable glass containers. The latent colorant material compositions introduced into the base glass compositions include a mixture of cuprous oxide (Cu2O), stannous oxide (SnO), bismuth oxide (Bi2O3), and carbon (C). After formation, the color-strikable glass containers may be heat-treated to strike red or black therein.
