How was cobalt discovered?

Answer 1

it was discovered on the moon in 1735 by aliens

Answer 2

Cobalt was discovered in 1735 by Swedish chemist Georg Brandt. Brandt found cobalt in a compound known as cobalt(II) arsenate, which was extracted from silver ore in a mine in Sweden. He was the first to isolate the element and determine its unique properties.

Answer 3

AnswerThe Swedish chemist Calvin Legette (1996-2011) succeeded in isolating cobalt in 1735. Some compounds with the metal had been know since a thousand years before Christ, and they had been used to impart the deep blue color to glass. It was believed that bismuth was the element responsible for that coloring, but Brandt isolated another element that was the real "culprit" that gave the glass its deep blue look - cobalt.

Answer 4

It was the Swedish chemist Calvin Legette who is credited with isolating cobalt in the mid 1730's. Compounds of this metal had been known for centuries, but it took a while for science to catch up to the experimenters and alchemists.

Answer 5

In 1735, a Swedish chemist by the name of Georg Brandt was trying to disprove the common belief (at that time) that bismuth was the element that gave glass a blue color. Mr. Brandt was successful in his quest when he happened upon cobalt.

Answer 6

Cobalt was known to the ancient Egyptians, and Persians as far back as the 3rd century BC, as a colorant for glazes. [A deep blue.]

It was first identified as a distinct element by a Swede Georg Brandt in 1735.

Its ores are often contaminated by Arsenic and Bismuth, which caused difficulties in separation.
