Description
A red color glass typically colored with small amounts of cadmium selenide. Ancient Egyptians made an opaque, blood red glass using cuprous oxide. Alternative colorants are colloidal metallic copper (transparent red) or gold chloride (purplish red). Trace amounts of metallic gold dissolved in glass produce a transparent pink color.
See also copper ruby glass.
