How long has cobalt been around?
Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1739. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth, as was commonly believed at the time. Cobalt’s primary ores are cobaltite (CoAsS) and erythrite (Co3(AsO4)2).
How was cobalt first discovered?
Cobalt was discovered in 1735 by the Swedish chemist Georg Brandt. Cobalt is usually recovered as a byproduct of mining and refining nickel, silver, lead, copper and iron.

How was cobalt formed?
Most cobalt is formed as a by-product of nickel refining. A huge reserve of several transition metals (including cobalt) can be found in strange nodules on the floors of the deepest oceans. The nodules are manganese minerals that take millions of years to form, and together they contain many tonnes of cobalt.

What is the half life of Cobalt 60?
Cobalt-60 has a half-life of 5.27 years and decays into nickel-60 through beta decay. Cobalt compounds have been used for centuries to color porcelain, glass, pottery, tile and enamel. Some of these compounds are known as: cobalt blue, ceruleum, new blue, smalt, cobalt yellow and cobalt green.

How long does it take to get cobalt poisoning?
Usually you have to be exposed to high levels of cobalt for weeks to months to have symptoms. However, it is possible to have some symptoms if you swallow a large amount of cobalt at one time. The most worrisome form of cobalt poisoning occurs when you breathe it into your lungs.
