Abstract:
Western alchemy and its unattainable objective of Chrysopoeia – metal transmutation – evoke connotations of the occult and unnatural. However, its practitioners, from Maria Hebraea to Isaac Newton, were, above all, dedicated, meticulous and highly resourceful experimentalists whose procedures and theories were rooted in real empirical observation of chemical processes. The firm belief in the possibility of transforming metals to gold and silver is a direct consequence of the various theories of materials and their transformations, built logically from the prevailing philosophies and known experimental facts. In the talk I will describe the chemistry behind some historical alchemical texts and trace the story of Western Alchemy from its roots in artisanal tricks in Roman Egypt up to the chemical revolution of the 18th century.
