History: “MS. 446" was produced in France, in the late 15th century, and is a rich example of an alchemical treatise. It is, however, devoid of most of the cryptic alchemical phrases, that are so enigmatic to us in the present day. It centers, rather, on the technical possibilities of the art. Amply illustrated, with 56 color drawings, it details 20 chemical procedures, and processes. The main text is followed by seven folios of full-page alchemical drawings, seven folios containing an alchemical synthesis, and three folios of practical recipes.
