It is found in small amounts in natural terrestrial nickel-iron and meteorites, in the Sun and stellar atmosphere, and in combination with other elements in natural water, in a ferromangan crust deep in the ocean.

He was able to demonstrate that cobalt is the source of the blue color in glass, which was previously thought to be due to the bismuth found with cobalt.Ĥ.
