Zinc is a bluish-white, lustrous metal with the chemical symbol Zn. Its main ore mineral is sphalerite (ZnS). Some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint. Year of first production.
