Antimony Glass or Caput Mortuum?

by Iulia Millesima

Ancient spagyrists knew that the mere division and re-union of four elements, repeated just a few times, did not lead to alchemical Sulphur but to Caput Mortuum, a  chemical salt.

spagyrical glass from antimonyBasilius Valentinus, in his  Triumphal Chariot of Antimony, first edition Leipzig 1624,  spoke about Antimony glass as a  tyro’s practice (in fact, it is part of the preliminary works):” … Here I write not to men skilled in this Art, who have often experienced the powers of the fire, but to Candidates, Tyro’s, and the studious Disciples of the Spagyric Science; because to make Glass of Antimony is a thing common, and well known to many. I say that every Glass, whether made of Metals, Minerals, or any other matter, must be thoroughly cooked in Fire to due Maturity, that it may have a clear and transparent Colour”.

There is a deep difference between ancient and modern spagyrics. The first one perfectly knew where spagyrics ended, and Alchemy began. Spagyric works were reserved only for preliminary works. While modern one shamelessly pretends to arrive at the last cooking. Nowadays, modern spagyric represents a problem for Alchemy, not a resource. When I began my pharmacology studies, Alchemy was seen as land to plunder. I, I must confess, at first thought of starting up a spagyric laboratory. As a young student, I wanted to try some ancient potable gold recipes to cure my severe anemia.

Here is an excerpt from an Italian spagyrist ( famed, indeed) teaching how to prepare antimony glass. At least he did not use hermetic terms. As you can see in the picture above, the result of this proceeding cannot but be Caput  Mortuum, a mere chemical salt sometimes soluted in alcohol. A tincture.   Indeed Caput Mortuum is composed of salts insoluble in water.

“Take a mineral and calcine it at a temperature that varies depending on the mineral. The powder obtained is put into a circulator with the addition of a menstruum (solvent, but in Alchemy, a chemical solvent is hardly called menstruum), in a certain proportion which also varies depending on the mineral used. When this is done, close the circulator (an alchemical solution is to be made in a closed vessel so as not to lose any vapor, while our modern spagyrist stoppers it when it is done). There are various circulators, but the most common and used is undoubtedly the Pelican – and put into moving around exposed to the sun and moon for a philosophical lunar month (28 days). ( this operation has a close resemblance with magnetization. Although, in my opinion, it is preferable to be carried out before Caput  Mortuum reduction in chemical salts. By the way, this is not compulsory )

After this period, open the circulator and let the menstruum evaporate, thus obtaining an oil, which is nothing more than the philosophical Sulphur of the ore and a colloidal metal. ( perhaps our spagyrist called this product sulfur because of a certain fixing or drying from excessive wetness).

Take now this colloidal metal, place it in a pelican, and pour a certain amount of tartarized alcohol on it. Make all circulate exposing to the sun and moon again for another philosophical lunar month (28 days). After this period, the solution is filtered, and the liquid obtained by filtration  will be nothing but the spagyric metallic dye.”

The procedure for obtaining a Spagyric dye from antimony is more complicated: Take the stibine and add a certain proportion of niter ( not specified, but one from experience can think of Potassium Nitrate, KNO3, Saltpeter. Generally used to lower down antimony ores smelting temperature)  and start calcinating for a time at a certain temperature. Then increase the temperature, and you get the glass of antimony.

This antimony glass is pulverized and placed in a pelican. Pour on a certain quantity of distilled vinegar and close, put to warm at a temperature of about 40 ° C, in other words, as alchemists said, at a temperature of incubating or fermenting manure, leave it for a philosophical lunar month.

Past this period, the solution is filtered and evaporated ( in Alchemy, one has to be careful not to lose any vapor. Anybody can dry, letting it evaporate from the open vessel), thus obtaining a powder that you will still put in a pelican, together with a certain amount of tartarized alcohol. You will close the circulator and let it move for another philosophical month. After this period, you will filter and finally get Spagyric Tincture of Antimony. All these dyes (he refers to these chemical products as  “ dyes” while, as aforementioned, they are mere alcoholic tinctures) contain no salt, but  colloids.”

basilius valentinus azoth 9Basilius Valentinus, retaking his Triumphal Chariot of Antimony, clearly understood that Antimony Glass is a part of the first-preliminary work, not the philosophical sulfur. On the left, from Basilius Valentinus “ Azoth”, you can see what the Birds are for: to raise Caput Mortuum or the dead head. A glass of antimony powder should then be raised or volatilized, even into a pelican. The philosophical sulfur is still far.
