Calamine is an obsolete name that may refer to hemimorphite, aurichalcite (green calamine) or smithsonite, but also other zinc oxide neoformation minerals. However, we still talk about botany flora calaminaire.

Until the 18th century, calamine was an essential source for the production of brass, because metallic zinc does not exist in nature and no technique was known to produce it. Etymology change the code

The term derives from the Greek kadmeia, the Cadmée region of Greece where there were mines whose walls of galleries, encrusted with these minerals, were at the origin of the idea, still alive in the XVII century, the regeneration of minerals.
