A glass has a basic soda-lime-silica glass portion, and a colorant portion including total iron as FeOselected from the group of total iron as FeOin the range of greater than zero to 0.02 weight percent; total iron as FeOin the range of greater than 0.02 weight percent to less than 0.10 weight percent and total iron as FeOin the range of 0.10 to 2.00 weight percent; redox ratio in the range of 0.2 to 0.8, and tin and/or fin compounds, e.g. SnOgreater than 0.000 to 5.0 weight percent. In one embodiment of the invention, the glass has a fin side and an opposite air side, wherein the tin side of the glass is supported on a molten fin 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 fin concentration hi 'body portion' of the glass.
