Melt two ounces of tin, and mix it with one ounce of mercury; when this is cold, pulverize it, and add one ounce of muriate of ammonia, and one ounce of sulphur, and grind them all together. Put the compound in a flask and heal it in a clear fire, (carefully avoiding the fumes,) till the mercury sublimes and rises in vapor. When the vapor ceases to rise, take the glass from the fire. A flaky gold colored powder will remain in the flask, which may be applied to ornamental work in the manner of gold bronze, of which it is a tolerable imitation.
