*bolded words mean you can find there definitions at the bottom
Zinc was first discovered in 1746. It was discovered in Germany by Andreas Marggraf. He discovered it by heating a mixture of calamine, ore, and carbon in a closed tube to create zinc. Zinc is a solid, soft metal with a shiny surface, and started out as a gray metal, but when polished, it turn bluish white. Zinc is very important in industry because it has the ability to work well with other metals.
