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 (Cu.sub.2O), stannous oxide (SnO), bismuth oxide (Bi.sub.2O.sub.3), and carbon (C). After formation, the color-strikable glass containers may be heat-treated to strike red or black therein.

An insulating glass unit cooling assembly and method of cooling an insulating glass unit is provided. The cooling assembly includes a cooling unit that directs air at insulating glass units and a conveyor that transports insulating glass units along a path of travel defining an axis of travel for the insulating glass units. The conveyor has a conveyor planar surface that supports a corresponding planar glass surface of the insulating glass units as the insulating glass units are conveyed along the axis of travel such that the planar surface of the insulating glass units are substantially horizontal and substantially parallel to the conveyor planar surface. The air from the cooling unit is directed in a path substantially parallel with the conveyor planar surface and the planar glass surface of the insulating glass units as the insulating glass units travel along the conveyor.
