Abstract: The invention is a colorless glass composition having a base glass composition, comprising, in weight percentage, from about 0.01 to 0.03 wt % of Fe2O3; about 20-30% reduction (% Fe+2) and about 0.05 to 1 wt % of TiO2, the glass having a visible light transmission of at least 89%, a ultraviolet radiation transmittance of no more than 81%; a solar direct transmission of no more than 90%; a dominant wavelength from 600 nm to 490 nm; and a purity of less than 2%.

Abstract: The invention is a glass composition with high visible light transmission and low ultraviolet light transmission, comprising, in weight percentage, less than 0.03 wt % of ferric oxide, from 0.05 to 1 wt % of titanium oxide and from 0 to 0.6 of cerium oxide, the glass having greater than 87% in visible luminous transmittance; a UV light transmission less than 60% and more preferably less than 50%; and, a solar direct transmittance no more than 90%.

Abstract: A neutral gray soda-lime-silica glass having a low light transmission (less than 20%), which reduces the transmission of solar energy, such as the transmission of near infrared radiation (less than 14%) and, in a greater degree, the transmission of ultraviolet radiation (less than 12%), comprising the following components in weight percentage:______________________________________ Fe.sub.2 O.sub.3 from 1.20 to 2.0% FeO from 18 to 28% (Reduction Percentage). Co.sub.3 O.sub.4 from 0.020 to 0.030% Se from 0.0025 to 0.010% CuO from 0.0050 to 0.050% ______________________________________This glass avoids the use of the coloring compounds such as the nickel, chromium and manganese.
