ABSTRACT:
The present invention provides a blue glass that can be essentially free of selenium and cobalt but still has a blue color and desired luminous transmittance. Additionally, the amount of iron present is comparable to conventional soda-lime-silica glass. The glass of the present invention can have a soda-lime-silica glass base portion, with major colorants that provide the blue color.
