The volatility of selenium in making selenium ruby glass has been studied. About 75% of the selenium added to the batch was lost by volatilization. Sodium selenite and barium selenite were stable at 950°C and are probably stable at higher temperatures. Regardless of whether selenium or the compounds studied are used, the resulting glass contains about equal amounts of selenium. Methods of preparing sodium and barium selenites are described. An outline is given of an analytical procedure by which selenium is determined in glass.
