Cobalt! Co

By: Joey


Cobalt was discovered by George Brandt in 1735 in Sweden. He had been successfully trying to prove that the blue color of glass was because of a new element, cobalt, and not bismuth, since the two are commonly found in the same place. The name cobalt comes from the German word "kobald" which means "goblin" or evil spirit.
