A bstract Data are presented on the development and production of ruby and other colors in glass by employing selenium as one of the colorants. The addition of 0.25% of powdered selenium and 0.30% of metallic cadmium with 0.055% of silicon as the reducing agents in a zinc‐free glass produced good ruby color. The addition of both oxidizing and reducing agents showed that conditions most favorable for the retention of selenium had an adverse affect on the retention of cadmium. The results of day‐tank trials embodying the principles found in this work are listed.
