History. Ores containing cobalt have been used since antiquity as pigments to impart a blue colour to porcelain and glass. It was not until 1742, however, that a Swedish chemist, Georg Brandt, showed that the blue colour was due to a previously unidentified metal, cobalt. In 1874 the output of cobalt from European deposits was surpassed by production in New Caledonia, and Canadian ores assumed ...
