Abstract
A glass has a basic soda-lime-silica glass portion, and a colorant portion including total iron as FeOin the range of greater than zero to 0.10 weight percent, e.g. selected from the group of total iron as FeOin the range of greater than zero to 0.02 weight percent and total iron as FeOin the range of greater than 0.02 weight percent to less than 0.10 weight percent; redox ratio in the range of 0.2 to 0.6, and tin and/or tin compounds, e.g. SnOgreater than 0.000 to 5.0 weight percent. In one embodiment of the invention, the glass has a tin side and an opposite air side, wherein the tin side of the glass is supported on a molten tin bath during forming of the glass. The tin concentration at the tin side of the glass is greater than, less than, or equal to the tin concentration in 'body portion' of the glass. The 'body portion' of the glass extending from the air side of the glass toward the tin side and terminating short of the tin side of the glass.
