For the record, there would seem to be some discussion of Bonacina's book on potable gold in:
"Representations Anciennes du Savoir Chimique et Alchimique"
Edited by Pierre Laszlo, Robert Halleux
Published by Université de Liège Bibliothèque
December 1980
and
Labyrintem tajemna, aneb, Průvodce po magických místech Československa
By Martin Stejskal, Albert Marenčin
Published by "Paseka", 1991
The latter would seem to be a work of popularization.
