    Abstract: A soda-lime-silica green glass favoring the yellow side, rather than the bluish side of the spectrum, is produced having high visible transmittance, low infrared energy transmittance, low ultraviolet radiation transmittance, and low total solar energy transmittance by manipulating the reduction of iron (as Fe.sub.2 O.sub.3) to FeO and the percent of these two oxides to achieve these characteristics without the use of CeO.sub.2 or other UV absorbing additives and by using conventional glass melting and refining apparatus.
