- A man by the name of
George Brandt discovered the element called Cobalt in 1735 in Sweden.
Cobalt is present in the human body in their blood, bones, the liver,
and the muscles in the human body. It is also present in the Earth's
crust, in the ocean water, in the atmosphere and it is also present in
the sun. It is found in compounds with arsenic, oxygen and sulfur. There
are Cobalt mines found in Zaire, Morocco, Sweden and Canada. It is used
in magnets, ceramics and in special glasses.
It is often used for electroplating to give
certain objects a surface that resists oxidation, but more times than
not it is used to form alloys.

The dangers of Cobalt are, if it is exposed to fire, the dust may
ignite on contact with air or oxygen, an explosion can occur when
finely dispersed particles from explosive mixtures in the air. There
is a risk of fire or an explosion on contact with oxidants or
acetylene. If you inhale cobalt, you begin to cough, you get a
shortness of breath, sore throat, and you begin to wheeze. If it
gets into your eyes, your eyes become red, and you need to rinse
with water for several minutes. If you eat cobalt, you begin to feel
pain in your abdominal area, and you begin to vomit. If any of these
incidents happen to you or someone you know, or anyone around you,
make sure they seek medical attention immediately.
