Does Sendivogius’ Alchemy Cancel the Celebration of the 250th Anniversary of the Discovery of Oxygen?

Gavazov, Blagovest K.; Gavazov, Kiril B.

2023 Chemistry-Didactics-Ecology-Metrology

doi:10.2478/cdem-2023-0003

AbstractMost chemistry textbooks claim that oxygen was discovered almost simultaneously by Carl Scheele and Joseph Priestley about 250 years ago. Priestley obtained oxygen by heating mercuric oxide (1774), and Scheele -by heating NaNO3, as well as by dissolving pyrolusite in sulfuric acid (1772)....
