  • Low transmittance glass
    Publication number: 20040186001
    Abstract: Low transmittance glass is composed of soda-lime-silica glass including 0.001 to 2 wt. % Li2O and, as colorant, 0.7 to 2.2 wt. % total iron oxide expressed as Fe2O3 (T-Fe2O3) . The glass has visible light transmittance (YA) of not greater than 65%, measured by using the CIE illuminant A, total solar radiation transmittance (TG) of not greater than 60%, and ultraviolet transmittance defined by ISO 9050 of not greater than 25%, when the glass has a thickness between 2.1 mm and 6 mm.
