Busardier. A Hermetic philosopher born in Bohemia who is credited with having made a genuine powder of projection. He left the bulk of his red powder to a friend named Richthausen, an adept and alchemist of Vienna. Some years after Busardier’s death, in 1637, Richthausen introduced himself to the Emperor Ferdinand III, who is known to have been ardently devoted to alchemy, and together they are said to have converted three pounds of mercury into the finest gold with one single grain of Busardier’s powder. In 1658 the Elector of Mayence also was permitted to test the powder, and the gold produced with it was declared by the Master of the Mint to be such, that he had never seen finer. Such are the claims vouchsafed by the city records and chronicles.
