Bronze glass composition |
摘要 |
The present invention provides a glass composition having a bronze color and a luminous (visible) transmittance of 70% or greater. The base glass is a soda-lime-silica composition and iron and selenium are added as colorants. In one particular embodiment of the invention, a bronze colored glass with a luminous transmittance (C.I.E. illuminant A) of 70% and higher at a thickness of 4.1 millimeters may be attained by using as colorants: 0.4 to 0.6 wt. % Fe2O3, 0.09 to 0.17 wt. % FeO and 3 to 11 PPM Se. In addition, it is preferred that the total solar energy transmittance be no greater than 60%.
