Color-strikable glass containers

A method of making glass containers, the method including:

• (a) providing a mixture of latent colorant materials including cuprous oxide (Cu2O), stannous oxide (SnO), bismuth oxide (Bi2O3), and carbon (C);
• (b) mixing the mixture of latent colorant materials with soda-lime-silica glass precursor materials to produce a batch of raw materials, wherein the soda-lime-silica glass precursor materials include at least one colorant selected from the group consisting of iron oxide, cobalt oxide, and chromium oxide;
• (c) melting the batch of raw materials in a glass batch furnace to produce molten glass having a color-strikable glass composition that includes at least one colorant selected from the group consisting of:
• iron oxide (Fe2O3), cobalt oxide (CoO), and chromium oxide (Cr2O3), wherein the molten glass comprises 0.2-0.6 wt. % iron oxide (Fe2O3) when the at least one colorant comprises iron oxide (Fe2O3);
• (d) forming glass containers from the molten glass;
• (e) annealing the glass containers;
• and
• (f) raising the temperature of a first one of the glass containers above a highest annealing temperature to impart red or black coloration thereto to produce a red or black glass container,
• wherein a second one of the glass containers is not heated to a temperature above the highest annealing temperature, and wherein the second one of the glass containers exhibits arctic blue, amber, cobalt blue, or emerald green coloration.
