In ancient or medieval alchemy, the philosopher’s stone was described as going through many color changes during its creation. Alchemist’s who wrote about “How to make the philosopher’s stone”, often depicted it as white, yellow, saffron, or even red. The Philosopher’s stone of alchemy was said to be wrapped in wax before the alchemist could attempt the transmutation of “quicksilver” or lead into gold. Quicksilver in alchemy was according to my theory or understanding, used to describe molten metal and not elemental mercury. Such hidden code words were used to keep outsiders from learning the craft or secrets of alchemy.
