Abstract:
A blue colored, infrared and ultraviolet absorbing glass composition uses a standard soda-lime-silica glass base composition and additionally iron, cobalt, and additional colorants selected from the group of Er2O3, Cr2O3, CuO, NiO, TiO2, Nd2O3 and combinations thereof. The glass of the present invention has a luminous transmittance of up to 60 percent, a dominant wavelength in the range of 480 to 489 nanometers and an excitation purity of at least 8 percent at a thickness of 0.160 inches (4.06 millimeters). The glass composition can form transparent glass panels that have varying limited LTA from one another as panel sets for mounting in automobiles.
