The present invention provides a high redox, ultraviolet and/or infrared absorbing radiation absorbing, and colored glass using a standard soda-lime-silica glass base composition and additionally at least on essential solar absorbing and colorant set of components. The solar absorbing flat glass article has two opposing major surfaces with a thickness of 1.5 to 12 mm. and a redox value in the range of greater than 0.38 to about 0.6, a retained sulfate measured as (SO3) value in the range of greater than 0.005 to less than 0.18 weight percent, and is essentially free of coloration from inorganic polysulfides. |
