Description
A naturally occurring mineral that may be white, yellow, red, green, or brown depending on impurities. Hydrated zinc silicate ore, hemimorphite, was directly mixed with copper for making brass. Zinc silicate ore is often found mixed with smithsonite (zinc carbonate) resulting in the early name of calamine being applied to both ores. Anhydrous zinc silicate ore is called willemite. Zinc silicate is phosphorescent and is used in television screens.
