recipe from Glauber’s writings (part 1)

Adjoin to the red salt, made of wood or carbon, a little of the powder of white flints. Put them into a crucible, and melt them in a fire that they may become a red glass, resembling almost the colour of a ruby. By continuing the fusion the red colour changes to green, and has the likeness of an emerald. After this comes a sky colour, resembling a sapphire. Then follows a yellow, not unlike a jacynth. Then, after a long continued heat, it becomes black, and like to an agate.

The purifying fire of alchemy book #16 kindle edition

the purifying fire of alchemy

This text describes the three purifying fires. Emphasis is given to washing certain things snow-white with a Philosophical Purgatory Flame. Glauber states, “He that does not know what Fire and SALT are, knows nothing, and deserves not the name of a Philosopher.” The ultimate goal is to prepare universal medicines for the bodies of men and metals. Many references are made to various texts by other Alchemists. First printed in 1689, it was restored and added to the R.A.M.S. (Restorers of Alchemical Manuscripts) Library by Hans W. Nintzel in 1983.
