An Artificial Synthesis Of Gold?
You Be The Judge

The select processes presented here, presumably appertaining to research and development of Jollivet Castelot, are facsimiles of photocopied excerpts once written out longhand by W.L.V...these are taken from a 20th century French text, concerning Castelot, translated to English.
This research is in character, considered to be worthy of publishing for the conceivable, intrinsic value. Inasmuch as it is not the goal of alchemists to lust vicariously after texts extolling transmutations to make gold, nevertheless, these experiments were found to be of alchemical interest back in the 1920's. Was Castelot on to something of an alchemical nature? In the increase of the gold found in the metals used he may have manipulated the seed of gold.

Dosage of Gold obtained by the second method -
The residue, which had been obtained by a mixture of:
Silver 10 grams
Tin 3 grams
Arsenic sulphide 3 grams
Antimony sulphide 3 grams
was crushed as much as possible and subdued (read: subjected) to a treatment of pure chloric acid like in the first method. [Here is a reference to a first method - not presented here - the above being the second method presented by Ballandras from a text, the name and size of which is unknown to me.]
However, to completely eliminate the silver and the tin employer, I scrupled to begin the indicated treatments, that is to say that the powder which was obtained having been subdued first to the action of azotic acid then washed with distillated water, then subdued to the action of chloric acid, then once more washed with distillated water, and these different operations were begun once more with another portion of pure azotic acid, and another portion of pure chloric acid after having carefully washed the insoluble residue was subdued to the prolonged action of aqua regalis following: Chloric acid - 15 parts/ Azotic acid - 4-5 parts.
[Page 126]
It must be noted that this thing happened during the ebullition (bubbling;boiling). The washed residue contained the slighter part of gold, this thing would be found dissolved in the last liquor, which I obtained. After 18 hours of digestion at the temperature of about 25 degrees, I subdued the mixture to ebullition during 3 hours.
After refrigeration, I filtered on wool of glass and I looked if parts were not drawn along in suspense. Finding nothing I proceeded to an analysis of the liquor which I obtained. For that month I made two parts strictly equal of the liquor, the first being destined to qualitative analysis, the other quantitative.

A) Qualitative Analysis: Assay of usual reagents:
Chloride of Tin - Rose colored precipitate
Pure Soda in solution - Voluminous yellow reddish precipitate
Sulfate of Iron - During ebullition, metallic precipitate, black greenish very dense spangles.

B) Quantitative Analysis:
The second part of the liquor destined to undergo quantitative analysis was treated by H2S when the most important part of chloric and azotic acids were driven out by a prolonged ebullition.
[Page 127]
This time the liquor was slightly acid and has a weak smell of chlorine. I called H2S into action; about 20 minutes long. The black precipitate which I obtained was received by a filter paper carefully washed first with well distillated water, then with hot water and at last with chloric acid.
After drying in the vapor-bath, the precipitate was put in a capsule of porcelain and heated in a mould at about 850 degrees, so as to destroy the sulphides precipitated with gold i.e., the arsenic and the antimony. These were naturally decomposed by the temperature of 850 degrees to which it had been subdued during two hours.
The quantity of gold obtained was 0.238 grains. The half of the liquor having served for the dissolution having been turned to good use for the qualitative analysis it followed that the whole quantity of gold contained in the original liquor should be equal to double the quantity obtained. i.e., 0.476 grains of gold per 10 grams of silver employed, yield then was 0.476 grains of gold per gram silver. {I must point out that the obtaining of gold is not a mathematical regularity, that is to say, the purport (proportion) of residue changes according to the conditions of heating.}
[Page 131]
I acted on 22 grains of chemically pure silver supplied by Messrs. Poulenc of Paris and on 3.5 grains of chemically pure orpiment supplied by the Pharmacie Central of Paris. The mixture was heated to about 1600 C in a metal smelting furnace for about hour. The residue obtained was again melted for an hour with the addition of orpiment, after having been hammered for half an hour and re-melted with the addition of small quantities of orpiment every 10 minutes, it was withdrawn.
After cooling and the addition of chemically pure antimony sulphide, it was again put back into the furnace, small quantities of orpiment being thrown in every 5 minutes. The residue obtained had a dark metallic tint, after hammering it became slightly golden.
Analysis of the Residue
The residue dissolved in chemically pure 36 degree HNO3 first cold and then hot, gave an abundant pulverulent deposit. This deposit after being washed and treated with HN3 to dissolve the arsenic and antimony salts was completely dissolved in aqua regia. The liquor after being chlorinated and filtered was subjected to the reagents of Platinum and gold.
[Page 132]
Mr. Andre Vandenberghe who was acting as preparator for this experiment, had thought that in accordance with the law of evolution of matter, the transmutation of bodies into gold should be preceded or accompanied by their transmutation into platinum. According to Mendeleiev's progression, we have Pt - 195.2 and Au - 197.2
The reactions of gold were quite characteristic; the reactions of platinum also seemed to reveal its presence. The quantity of gold obtained in this experiment was estimated at about one gram. I emit the hypothesis that the arsenic acts as a catalyzer and the sulphur as a ferment in this transmutation.

By M. Jollivet Castelot
All my research work on transmutation since 1908 has started from the fact that gold is found in nature associated with antimony and arsenic sulphides as well as with Tellurium which is considered as the mineralizer of gold. I therefore considered it logical to introduce Tellurium into the artificial combination of silver and arsenic and antimony sulphides that I make. The following is an account of one of my recent experiments:
I prepared a mixture composed of 6 grams of chemically pure silver, 1 gram of native orpiment (Arsenic trisulphide A52S3) free from gold, 1 gram of chemically pure antimony sulphide, and 2 grams of chemically pure Tellurium. I added pure silica to the usual fluxes. This mixture was heated in the furnace in the usual way for one hour at a temperature of 1100 C (approximately) [note: parenthesis are not mine AMWH]

[Page 134]
The residue obtained was of a blackish grey color with violet reflections. It weighed 6.420 grains. When subjected to the action of nitric acid, the residue was attacked with difficulty and greenish metallic particles became detached. The solution was then decanted and a greenish-yellow residue remained which was kept at the boiling point in nitric acid for several hours, after decanting off the liquor once again, the residue, which had not changed, was washed, treated with ammonia and then subjected to the action of aqua regia in which it was entirely dissolved after boiling for several hours.
The solution after being chlorinated and then subjected to the reagents of gold, gave the following:
Potassium Ferrocyanide - greenish brown coloration.
Tin Protochloride + Tin Bichloride - a yellow bronze coloration and then a metallic deposit of the same shade.
Ammonia - coloration and precipitate identical with the preceding one and which became transformed into a yellow deposit of fulminating gold at the end of a few hours.
Formol - light yellowish black metallic precipitate.
Peroxide of Hydrogen - light very finely divided brownish black precipitate.
Oxalic acid - yellowish black precipitate.
Ferrous Sulphate - golden yellow metallic precipitate.
Caustic Potash - a fairly abundant golden yellow metallic precipitate at the end of a few hours.
The presence of gold was therefore very distinctly shown and a remarkable feature was that the metal obtained possessed the yellow bronze color of gold telluride and of native silver. I had therefore produced a bronze colored gold in my laboratory by artificial means thanks to the intervention of the Tellurium.
A certain amount of gold was certainly lost in this test as in all my previous tests, for it is known that arsenic, antimony and Tellurium entrain gold in their fusion and their volatilization. In order to obviate this disadvantage, I had thought of making the vapors of arsenic and antimony sulphides and of Tellurium act on the silver in fusion in a closed vessel by means of a special device, but I have been forced to give up this scheme for the time being on account of the difficulties met with for the construction of this apparatus, the cost of which would be very high. I consider it certain that if the vapors were allowed to bubble through the melted silver, a much higher yield of gold would be obtained than that I have obtained hitherto by an imperfect and too rapid contact of the bodies in presence; while it is undoubtedly necessary to make them react on one another in the state of vapor in a closed vessel.

As a sequel to my previous work on the artificial synthesis of gold, I have introduced Tin into these new tests as it is also often associated with gold in nature. The following is a description of this new process, thanks to which the percentage of gold obtained destroys all the objections that are raised with regard to impurities.
I made an intimate mixture of 6 grams of chemically pure silver of which the purity was tested by a professional chemist, the Head of the laboratory of one of the most important Works of the region. 2 Grams of antimony sulphide, 1 gram of orpiment, and 1 gram of Tin; all these bodies were obtained from the Establishment Poulenc of Paris and were chemically pure. I added the usual fluxes and then heated the whole in a crucible in the furnace to about 1100 C fort2 about 1 hour, twice adding a small quantity of antimony sulphide.
The residue obtained was treated for a long period in pure 36 degree nitric acid, first cold and then at the boiling point.
[Page 138]
The insoluble residue was next washed with distilled water, treated with ammonia, washed again and finally treated for a long period with boiling aqua regia. The liquor when filtered and subjected to the reagents of gold showed the presence of this metal in the form of deposits3 which maybe estimated at 0.05 grains in all, which is very high considering the 6 grams of silver employed.
With Oxalic acid, the solution turned violet and gave an abundant black pulverulent precipitate.
With Hydrogen Peroxide, a very finely divided precipitate of gold.
With Formic Aldehyde, a brown precipitate of gold.
With Tin Protochloride, an intense violet pink coloration.
The addition of Tin to the other bodies has certainly facilitated the reactions of the gold and increased the yield of this metal which can be manufactured artificially by my process.
[Page 139]
It would be easy to show that, given the respective prices of gold and of the other substances that are used in my process to produce it, a profit could be obtained if the process were worked industrially; all the more so as the greater part of the silver employed can be recovered at each test.
I believe I now hold the key to the regular and even industrial manufacture of gold. But the industrial question is voluntarily put aside from my thoughts, for my only object is the search for pure scientific truth.

"It must be admitted that it is extraordinary and incomprehensible that France for the past ten years has refused to take an interest in the experiments of a rich and universally respected scientist who has given proofs of his worth, even after the conclusive experiments carried out by an official chemist, Mr Ballandras of Lyons."
Andre Ibels, La Razon, June 8, 1927
"It is unjust, gentlemen, that a scientist of the value of Mr. Jollivet Castelot should be held in suspicion at the very moment when he is losing his sight through overwork. To continue his work, however embarrassing it may be to yours, is a sacred duty."
Declaration by Mademoiselle M.L. of Paris.
Professor of Engineering at the Conservatoire
des Arts et Metiers, Paris, at the Chemical Congress in Paris. October 1927
"Oh! it is not that Mr. Jollivet Castelot has not attempted to make his invention known in France, on the contrary, he has written leaflets and books and has founded reviews for this purpose... Not only was he not taken seriously, but he was also a butt to the sarcasm and even to the insults of the official scientists in general and of the Nobelist Perrin in particular. The Acedemie des Sciences itself - as usual - refused to record his communication."
