  • Patent number: 6413893
    Abstract: The present invention provides a green colored, infrared and ultraviolet absorbing glass article having a luminous transmittance of up to 60 percent. The composition of the glass article uses a standard soda-lime-silica glass base composition and additionally iron, cobalt, selenium, and chromium, and titanium, as infrared and ultraviolet radiation absorbing materials and colorants. The glasses of the present invention have a color characterized by a dominant wavelength in the range of about 480 to 565 nanometers, preferably about 495 to 560 nanometers, with an excitation purity of no higher than about 20 percent, preferably no higher than about 10 percent, and more preferably no higher than about 7 percent. The glass compositions may be provided with different levels of spectral performance depending on the particular application and desired luminous transmittance.

  • Patent number: 5830812
    Abstract: The present invention provides a green colored glass using a standard soda-lime-silica glass base composition and additionally iron, cerium, chromium and, optionally, titanium as infrared and ultraviolet radiation absorbing materials and colorants. It is preferred that the glass have a green color characterized by a dominant wavelength in the range of about 500 to 565 nanometers with an excitation purity of no higher than about 5% and include about 0.50 to 1.0 wt. % total iron, about 0.26 to 0.65 wt. % Fe.sub.2 O.sub.3, about 0.05 to 3 wt. % CeO.sub.2, 0 to about 2 wt. % TiO.sub.2, and about 20 to 650 PPM Cr.sub.2 O.sub.3. The redox ratio for the glass is maintained between about 0.20 to 0.55.
