Controversies
Vaughan quarrelled in print with Henry More. Their pamphlet war petered out, but More returned to the subject of alchemists in Enthusiasmus Triumphatus (1656). Another critic of Vaughan was John Gaule.
Vaughan fell out with an alchemical collaborator, Edward Bolnest, over money matters and alleged broken promises, and the matter came to litigation after Bolnest had threatened violence. Vaughan was accused as part of this affair of spending 'most of his time in the study of Naturall Philosophy and Chimicall Phisick'. He is reported as having confessed that he had 'long sought and long missed ... the philosopher's stone'.
