Humans have been using compounds of cobalt since at least 1400. The compounds were used to color glass and glazes blue. In 1735, Swedish chemist Georg Brandt (1694-1768) analyzed a dark blue pigment found in copper ore. Brandt demonstrated that the pigment contained a new element, later named cobalt.Cobalt is a transition metal, one of several elements found in Rows 4 through 7 between Groups 2 and 13 in the periodic table. The periodic table is a chart that shows how chemical elements are related to each other.or example, it is used in a test known as the Schilling test. This test is a method for determining whether a person's body is making and using vitaminB 12 properly. Two other isotopes of cobalt, cobalt-57 and cobalt-58, are used for the same purpose.
