Axel Fredrik Cronstedt

Born 23 Dec 1722; died 19 Aug 1765 at age 42. Swedish chemist and metallurgist who was the first to isolate nickel (1751) and notice its slight magnetic properties. A new chemical classification of minerals he made was translated to several languages. Patterns he found in the internal structure of minerals enabled him to distinguish between simple one-compound minerals and those comprised of a mixture of several minerals. He discovered zeolite, a water-softening silicate and analysed the high-density mineral calcium tungstate. By adept use of the blowpipe to intensify a flame and burn a small quantity of a mineral he could make an identification of its chemical composition based on the colouring of the flame. He did not invent the instrument, but founded systematic blowpipe analysis technique.«
