  • Patent number: 9617182
    Abstract: The present invention relates to a low-transmission dark mist green glass composition, more specifically relates to a low-transmission dark mist green glass composition in which Fe2O3, CoO, Se and Cr2O3 are used as coloring components within a specific content range where for the coloring components the relative contents of (CoO+Cr2O3) to Se and CoO to Cr2O3 are restricted to certain ranges and accordingly the visible transmittance (LTA) is effectively controlled and thus a blocking performance for privacy is satisfied; the solar energy transmittance (Te) and the UV transmittance (Tuv) are lowered, and accordingly the cooling load for vehicles, buildings and the like is reduced and interior materials and people protection against UV rays is obtained; and the optimal range of chromaticity diagram of transparent colors is satisfied which accordingly reduces eyestrain and provides psychological stability.
