History of Zinc
Centuries before zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds for medicinal purposes. Zinc compounds were in the ores smelted certainly as early as 200 B.C. to obtain copper and which gave alloys of copper and zinc – the brass family. The Romans certainly were major users of brass. The Greeks also appeared to know zinc, even if not by name.
