Zinc was known in Roman times in combination with copper as the alloy brass. The metallurgists of India isolated the metal around the 13th century, and in the 16th century, there was large-scale production of zinc by the metallurgists of China. | Uses - batteries, galvanizing, brass, roof cladding, protection for iron structures, coins |
