Metallic zinc was produced in the 13th century A.D. India by reducing calamine with organic substances such as wool.

The metal was rediscovered in Europe by Andreas Sigismund Marggraf in 1746.

He heated a mixture of calamine ore and carbon in a closed vessel without copper to produce the metal. From the German word Zink, of obscure origin 42 1781 Carl William Scheele Sweden From the Greek word "molybdos" meaning "lead"

Zinc is not considered to be particularly toxic
Zinc is referred to in nonscientific contexts as spelter
Because of its corrosion resistance, zinc is often plated to other metals in a process called galvanization.

Zinc is an essential trace element for animals and plants.

Large quantities of zinc are used to produce die castings, which are used extensively by the automotive, electrical, and hardware industries.
