History of discovery

Zinc was known to the Romans but rarely used. It was first recognized as a metal in its own right in India, where a zinc furnace at Zawar in Rajasthan contained large quantities of zinc, proving large-scale refining between 1100 and 1500.

Large-scale refining of zinc took place in China in the 16th century. An East India Company ship sank off the coast of Sweden in 1745. Its cargo was Chinese zinc, and analysis of the recovered ingots proved that they were almost pure metal.

In 1668, the Flemish metallurgist P. Moras de Respour extracted metallic zinc from zinc oxide, but Europe believes that zinc was discovered by the German chemist Andreas Marggraf in 1746, and Indeed, he was the first to confirm that it was a new metal.
