At last, the Alkahest of Iron Citrate. It is sufficiently powerful to volatilize the fixed salts of iron, and probably a number of other fixed salts.
The black Earth here will be dried, ground, calcined, ground some more, calcined some more, and alchemically calcined with bespoke strong mineral acids before reintroduction of the Earth to the Alkahest.
Alchemy is essentially a game of recognizing living matters, killing them, and finessing that fugitive life force into a simpler, 'thinner' host matter. The alchemist is the nurse, the undertaker, the funeral director, and the resurrector of matter.
The Alkahest, like the Eagle, carries the body of iron with it over the still head. Iron is the Eagle's food, and they become one essence.
When the Alkahest has utterly consumed the body of iron, it is then called Our Mercury. Philosophic Mercury. The Water of Life.
It is then useful for producing Third Order Alchemical Sulphurs of metals. They are incomparable precious sacraments, ingested by the drop, in order to achieve higher and deeper levels of mystical consciousness.
I have ingested all sorts of Alchemical Sulphurs, and those made by Our Mercury are the best.
The Sulphur of Tin prepared by dissolving tin oxide (Cream of Tin) in Philosophic Mercury and then distilling it off, will transmute hot copper metal into the finest silver.
The Sulphur of Iron tinges higher than that of gold, allegedly, according to Thomas Vaughan. I have been studying his works rather deeply.
A friend of mine has prepared the Sulphur of Copper, and he claims it is the best smelling most fragrant of the metallic oils - like perfume!
Common mercury Hg will dissolve in Our Mercury too, rendering a transmutation agent. I would be most cautious before ingesting such a substance however, since Hg is a pernicious toxin.
We have a great many more metals available to us nowadays that we may experiment at liberty with. I intend to produce a Sulphur of Manganese at some point, as well as Vanadium. Perhaps Bismuth? We shall see.
