Properties of these salts

I have observed that these salts are extremely refractory and not fusible to the hottest fire, like talc-like earth.

They allow themselves to dissolve without effervescence in the spirit of concentrated salt and, as they do not unite exactly with it, they can be crystallized again and brought back to their first form.

They unite exactly with phosphoric acid and then appear as real metallic salts, easily soluble and fusible.

EXPERIENCE

Take the benzoic flowers, dissolve them in water and crystallize this solution. The salt obtained and dried will not be fusible in the fire.

Phosphoric acid is taken, it is combined with these salts, it is recrystallized and a pure metal salt is obtained.

Use of metal salts and their role in the production of metals

These salts unite easily with phosphoric and metallic sulfur, immediately exhibiting the opacity and shine of the metal.

They possess an extremely constrictive force, by which phosphorus (or sulfur-metal) loses its flammability and acquires metallic hardness.

These salts also exert a special action on mercury; they penetrate it intimately and are able to transform this liquid metal into fine silver. But, for this transformation, one should only use the silver salt; it does the best service and you get it by separating the money as follows.

EXPERIENCE

How, by the dissociation of silver, we can obtain the pure salt of SAL LUNAE silver.

Silver which has become spongy or silver which has been finely pulverized or amalgamated to render it capable of dissociation, is placed in the reverberatory furnace, and it is covered with phosphorus. The mixture is placed in the heat for a few days and allowed to digest.

    The Benzoic Flowers, that is to say the salt of the previous experience. Phosphoric acid is here, of course, our .
    

At first, silver loses its shine and polish, appearing as a colored, resinous body which, when heated, melts into a pasty, sticky and tenacious mass, which can be completely evaporated in a vacuum.

This operation completed, the separation of the parts is undertaken. The metallity of silver has disappeared; the “bound” element (ie phosphoric acid in silver) has joined with the phosphoric acid used for the operation; the binding parts of the silver are separated from the "bound". They hold together only by their affinity and, according to the law of affinity, it is also by means of other chemically related bodies that they can be separated.

But, before this separation can be skilfully attempted, the acid dissolving medium, phosphoric acid, must be extracted, for otherwise the component parts could not be completely extracted. The manipulation is as follows

As was clearly shown above, as soon as the silver has been transformed and dissolved in its digestion with phosphoric acid (which changed it into a resinous and sticky mass), salt is poured into this solution. urine [ammonia salt] dissolved in distilled water. This immediately absorbs all sulfur and phosphorus, and leaves the binding parts of the silver intact, c. to d. silver earth, coloring earth and talciform.

This residue is leached and de-sugared with distilled water. So we start to dissociate its binding parts.

The noble metals contain both earth colors and talc-like earths. A solution of spirit of salt and nitric acid is therefore poured at the same time on the residue. This solution absorbs the residue.

Nitric acid absorbs talc-like soil.

This earth is separated by the addition of an alkali salt which produces a precipitate. When the latter is desiccated and desiccated, a white, oily earth with a soapy consistency is obtained, which is the true metallic earth similar to talc.

When this desugarated residue is placed in a solution of mercury and nitric acid, the talc-like earth dissolves in the acid and the salt, uniting with the mercury, sinks to the bottom with it.

The mercury is then removed by distillation and the salt remains at the bottom, in the form of a reddish earth, which resists fire.

This salt is taken and dissolved in phosphoric acid, with which it unites perfectly. If it is allowed to reform into crystals, a pure silver salt is obtained.

OTHER EXPERIENCE

When we digestion of gold made spongy with phosphoric acid and then the acid is distilled off, a brown-red salt is obtained which is very easily vitrified. This salt gives color to each metal with which the lime is amalgamated.

This salt could be the land of the philosophers - their field - from which they derive their metal32.

-o- ABSTRACTIONS

This fixed salt, digested once again with phosphoric acid and left to crystallize in a cellar, was dried by the Ancients into a powder which they used as medicine.

This salt, pulverized with golden lime and enclosed in a dry flask, transforms at low heat into a blood-red liquor33.

This liquor can be fixed on lamp fire

This fixed, pulverized, and placed on mercury, 34 worked by degrees in a closed crucible, gives a tingent powder (Tingirendes Pulver).

If we dissolve a portion of gold lime in our phosphoric acid, separate the residue and pour over the clear solution35, we obtain a red gold oil.

Based on these various ways of operating, if we mix the lime with our acid, we can make all the olea metallorum.
OTHER EXPERIENCE

We amalgamate fine gold with our acid; the acid is removed, then the gold is calcined; we amalgamate again with our acid, we separate the left to digest for 24 hours, and a yellow powder is obtained and, finally, a red salt.

If we take the red-brown salt and put it in our vinegar, we get tasteless water and salt.

If this water is poured over the above powder, the salt is obtained again.

Eight grains of phosphoric acid dissolve a grain of golden lime in heat and 'transform it into a blood-red liquor36.

By digestion, this liquor gives all the colors and, finally, it becomes like burnt blood, but with a special luster.

If we want to increase this product, we must dissolve the gold again in our acid, take half of this product, triturate it in a glass, mix with the solution, then digest it again, as already described.

    The base, still imperfect, of the sulfur of the philosophers, the obtaining of which is the object of the second work.
    

<sup>33 Aurific oils.

34 Philosophical Mercury. Fixing a lamp to the state of elixir requires great caution or great daring. The technique is different when using the closed crucible or the glass flask. The duration of work also.

35 The clear solution: the blood-red liquor. This process is not the result of making dye powder, but is entirely distinct from it.

36 Proportions to remember.</sup>

Time is always decreasing. As in the first operation four months were used, in the second it will only take three weeks, in the third three days and; at the end only three hours for the entire completion.

When four grains of the first product are mixed with fifty of purified mercury and allowed to cool, a red powder of particular strength is obtained.
