3d 7 Cobalt was discovered by George Brandt in 1735 in Sweden. Minerals containing Cobalt were of value in the early egyptian and mesopotamian eras for its ability to tint glass a deep rich blue. George Brandt tried to explain that Cobalt was the element in coloring glass blue instead of the element found in the same location, Bismuth.
Cobalt is a transition element on the periodic table.
The uses of Cobalt cosist of being alloyed with other metals for example it alloys with nickel to make Alnico, a metal with an usually high amount of magnetism. It also is used in magnet steels and stainless steels, along with it being used in Jet turbines and Gas turbines. Another common use for it is electroplating due to its ability to resist oxidation.
