"I recently read The Secrets of Alchemy by Lawrence Principe, which I loved, especially because he tries to replicate ancient alchemical recipes in his own lab. And sometimes he succeeds!
For instance, he attempts to make the “sulfur of antimony” by following the instructions in The Triumphal Chariot of Antimony (Der Triumph-Wagen Antimonii), written by an alchemist named Basil Valentine7 sometime around the year 1600. At first, all Principe gets is a “dirty gray lump”.
Then he realizes the recipe calls for “Hungarian antimony,” so instead of using pure lab-grade antimony, he literally orders some raw Eastern European ore, and suddenly the reaction works! It turns out the Hungarian dirt is special because it contains a bit of silicon dioxide, something Basil Valentine couldn’t have known."
