Try to smelt it, you get toxic fumes of arsenic oxide
and cobalt oxide, a useless powder instead of metal.

Superalloys of cobalt with nickel, tungsten, chromium, titanium
make turbine blades and knee replacements.
The cathodes of lithium-ion batteries contain cobalt,
nickel-cadmium, nickel metal hydride batteries also contain cobalt.
Blend with aluminum for cobalt blue, with zinc for cobalt green,
with tin for cerulean blue, with phosphate for cobalt violet.
Stuff that jinxes
It’s not that you couldn’t
but that you won’t try.
It’s all in your head,
if you think they’re out to get you.
It’s useless or harmless,
as far as you know, but what
do you know? Answers
won’t come until it’s too late.
They say that what you
don’t know won’t hurt you,
but what about the witches
stirring their pot in the woods?
Don’t speak of the devil,
though now it’s been done.
Hear him knocking in the dark.
Cross your heart and knock on wood.
You can’t tell he’s not here.
You just can’t see him—
a little green man dressed in rags
and making things go awry.
Other chemists disputed Georg Brandt’s claim that cobalt was an element,
asserting that he merely had a compound of iron and arsenic.
Maybe it was easy to dismiss his claims, given the metal had a name that translates as “goblin.”
