Color-strikable glass containers

Latent colorant material compositions, silica-soda-lime glass compositions and related methods for making colorable 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 colorable glass compositions and colorable 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 colorable glass containers can be heat treated to become colored red or black. (Automatic translation with Google Translate, no legal value)
