Cobalt: historical information. Cobalt was discovered by Georg Brandt at 1735 in Sweden. Origin of name: from the German word kobald meaning goblin or evil spirit. Minerals containing cobalt were of value to the early civilisations of Egypt and Mesopotamia for colouring glass deep blue.
Free cobalt (the native metal) is not found on Earth because of oxygen in the atmosphere and chlorine in the ocean. Oxygen and chlorine are abundant enough in the upper layers of the Earth's crust to prevent the formation of native metal cobalt.
