Abstract
A glass has a basic soda-lime-silica glass portion, and a colorant portion, the colorant portion including total iron as Fe2O3 in the range of at least 0.10 to no more than 2.00 weight percent, a redox ratio in the range of 0.35 to 0.6, and tin metal providing tin in an amount within the range of greater than 0.005 to 5.0 weight percent; the glass product has a tin side and an opposite air side, said tin side of the glass having a higher concentration of tin than the air side, the air side having a uniform concentration of tin from the air side of the glass product towards the tin side of the glass product.
