Cobalt metal is solid and silvery-grey at normal pressure and temperature, Cobalt metal is a very hard material. Cobalt metal is ferromagnetic and ductile, which is very similar to iron metal, but is much rarer than this. It is used for magnets and for many different alloys. Cobalt blue, CoAl2O4, is one of the most important blue colorants for glass and ceramics. Also cobalt is part of the vitamin B12 and therefore is needed in small amounts in our food.
Cobalt metal is another dangerous metal, must be handle with gloves and care.
