  • Colored glass compositions and-automotive vision panels with-reduced transmitted-color shift
    Patent number: 7071133
    Abstract: A neutral gray colored glass composition for automotive vision panels having reduced transmitted color shift characteristics is provided. The glass composition has a base portion including 65 to 75 weight percent SiO2, 10 to 20 weight percent Na2O, 5 to 15 weight percent CaO, 0 to 5 weight percent MgO, 0 to 5 weight percent Al2O3, and 0 to 5 weight percent K2O. The composition also includes major colorants including 0.30 to 0.75 weight percent Fe2O3, 0 to 15 ppm CoO, and 1 to 15 ppm Se. The glass has a luminous transmittance of at least 65 percent at a thickness of 3.9 mm, a redox ratio of 0.2 to 0.675, a TSET of less than or equal to 65 percent, and a standard color shift of less than 6.
