, and denounced the deceptions of fraudulent people who pretended to effect the transmutation of metals (this does not mean he did not believe in transmutation, though; in his "Experimental Confirmation of Chymical Philosophy" alone he claims to have achieved at least three different transmutations), he believed mercury to be a constituent of all metals and heavy minerals, though he held there was no proof of the presence of "sulphur comburens".

As is discussed in his ''Laboratorium chymicum'', Kunckel was involved in early experiments into the production of explosive mercury.
