Zinc (Zn) was used in Rome and China more than 2000 years ago as a component of brass which is a zinc-copper alloy. The Romans and Chinese smelted zinc ores such as calamine (zinc carbonate) with copper to produce brass, used for coins, containers, armour and jewellery. They did not actually realise that zinc was a metal.
