Glass of Antimony
Roast powdered antimony in a shallow vessel over a gentle fire, until it turns whitish gray, and ceases to emit fumes at a red heat; then heat it in a crucible until it fuses into a brownish red glass. If calcined too much, a little more antimony must be added to make it run well.
