The present invention relates to a composition comprising a base soda-lime-silica glass part; And 0 weight% to 0.02 weight% of Fe 2 O 3 as the total iron, 0.02 weight% to 0.10 weight% lower than in the Fe 2 O 3 as a total of iron and 0.10% to 2.00% of the total as Fe 2 O 3 wt. (For example, more than 0.000% by weight to 5.0% by weight of SnO 2 ), total iron as Fe 2 O 3 selected from the group of iron, a redox ratio of 0.2 to 0.6 and a tin and / ≪ / RTI > In one embodiment of the present invention, the glass has a tin surface and an opposite air side, wherein the tin surface of the glass is supported on a molten tin bath during the formation of the glass. The tin concentration on the tin surface of the glass is greater than, equal to, or less than the tin concentration in the "body portion" of the glass. A "body portion" of the glass extends from the air side of the glass toward the tin surface and terminates below the tin surface of the glass. |
