One of the (many) subjects I’m researching for the book is Renaissance alchemy. Both John Dee and Edward Kelley practiced it and the latter made his name in Bohemia when he successfully “transmuted” gold. As such I need to have some idea of what they were really doing.
Getting my head around this topic remains a chore. I had to wade through a ton of books that looked promising only to discover they were about something completely different (nineteenth century and later “new age” fads using alchemical transmutation as a metaphor for self improvement) or only tangentially related (medicinal alchemy – fascinating! – but no). Facsimiles and translations of historic primary sources exist (the Folger Shakespeare Library’s Digital Image Collection has high-res scans) but the language and imagery are so laden with symbolism that they are almost impenetrable to non-academics.
Finally I located what may be the only “beginner’s” guide to good old-fashioned gold transmuting-type alchemy, Lawrence Principe’s Secrets of Alchemy. It covers the history of alchemy (transmutation and otherwise) from ancient times to the twentieth century and clearly explains the rationale behind beliefs that seem ridiculous to modern minds.
To hilariously simplify: early modern alchemists assumed that all metals were compounded from salt, sulfur, and mercury. Starting from this incorrect assumption it followed logically that altering the proportions or qualities of one or more of these could turn one metal into another.
They weren’t just guessing or making stuff up randomly either. Practitioners were methodical in their experiments and recorded recipes and outcomes. Of course nobody really turned lead into gold but their results were dramatic enough to suggest it was possible.
Principe followed a few historic recipes himself and came up with results similar to what was described, provided he used period-accurate supplies (raw ore instead of purified modern chemicals). William Newman’s Chymistry of Isaac Newton project performed some of Newton’s experiments and includes both videos of their experiments and a modern explanation of what’s really going on.
What I need for my story are:
1) a process (or slight of hand) that produces convincing fake gold, and
2) a process that results in enough pure gold for Kelley to think he’s actually transmuted gold
And my chemistry-illiterate self needs to write these in a way that is both engaging and believable without getting bogged down in detail that will bore the reader.
Oh yeah. This will be fun.
