Abstract

See full text

A glass has a basic soda-lime-silica glass portion, and a colorant portion including total iron as Fe2O3 selected from the group of total iron as Fe2O3 in the range of greater than zero to 0.02 weight percent; total iron as Fe2O3 in the range of greater than 0.02 weight percent to less than 0.10 weight percent and total iron as Fe2O3 in 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. SnO2 greater 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. The “body portion” of the glass extending from the air side of the glass toward the fin side and terminating short of the tin side of the glass.
