History
Middle Ages
Metallic zinc was produced at Zawar, Rajasthan, long before its European identification. The date is not a single year.
European identification
Identification · confirmed · 1746
Marggraf identifies zinc as a distinct metal. That does not date Indian metallurgical production, which is older and has no single year.
