Career
Cronstedt described it as kupfernickel. This name arises because the ore has a similar appearance to copper (kupfer) and a mischievous sprite (nickel) was supposed by miners to be the cause of their failure to extract copper from lieutenant Cronstedt named it nickel in 1754.
He was a pupil of Georg Brandt, the discoverer of cobalt.
Cronstedt also discovered the mineral scheelite in 1751. He named the mineral tungsten, meaning heavy stone in Swedish.
Carl Wilhelm Scheele later suggested that a new metal could be extracted from the mineral. In English, this metal is now known as the element tungsten.
In 1756, Cronstedt coined the term zeolite after heating the mineral stilbite with a blowpipe flame.
