Historia
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.

Användningsområden
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.
Zinc is not considered to be particularly toxic
