Webb9 maj 2024 · Phlogiston was a substance believed to be emitted during combustion and the calcination of metals . Earlier chemists, such as the Germans Johann Becher (1635 – 1682) and George Stahl (1660 – 1734), supposed that a metal was composed of calx and phlogiston, and that burning resulted from the loss of phlogiston. WebbAlthough Gadolin accepted the phlogiston theory early in his career, he attempted to understand Lavoisier’s ideas. In a paper published in 1788 he tried to define phlogiston and admitted that the French explanation of combustion was superior to some phlogiston theories, but for a long time he was not wholly converted. citethisforme.com apa referencing
