After re-reading and examing all posts from this forum i noticed to my surprise how very little of practical knowledge one may find it here.If there is maybe are a process or two that are exceptions to the rule, they are often not complete or at least one ingredient is hiddden. No wonder that one user asked me what is the "secret fire" and philosopher' stone in my Roger Caro thread!

So i decided to share some of the information that i received from a charitable hand of my brother who want to stay unknown!

I apologize for my grammatical mistakes, english is my third language.


Saltpeter salts are very popular among alchemists, it is designated by various names: nitre, salt of nitre, but he describes his original "rock salt" which is attached, is derived from the Latin salpetræ - salt stone.
Chemists call it the potassium nitrate or potassium nitrate, and describing its composition. The chemical formula KNO3 is potassium nitrate, molecular weight 101.1 g / mol, it is decomposed by melting at 400 ° C. Its solubility in 1 liter of water varies greatly with temperature, it increases from 130 g to 0 ° C to 270 g at 20 °, 410 ° to 60 g and 2470 g to the boil.
In passing we note that the solubility of sea salt (which is always associated), remains almost constant at 360 grams per liter and thus offers a way of being (largely) removed easily.
The natural saltpeter from the chemical combination of nitrogen from the air and oxygen under the action of electric discharges in the atmosphere, it forms nitric acid which, when combined with elements in the soil, produces nitrates of lime, soda, potash or magnesia.
It is the same in places rich in nitrogen as the stables where the walls impregnated wet slurry promote its formation. The organic matter back slowly into the walls of buildings where they meet air and nitrifying bacteria for the production of saltpeter. This salt, forming, attack the stones of the walls on which the emerging (saltpetre may be collected by brushing, the saltpeter hood). All deposits satisfies the conditions of humidity and the presence of decaying organic matter (generating nitrogen) mixed with stones and rubble, are the producers of saltpeter.

A little history:
The enormous needs of saltpetre for making gunpowder, especially after the French Revolution, led to a real hunt with saltpeter requisition, sometimes aggressive, in individuals who were thus deprived of the earth swallow of saltpetre recovered at the bottom of their walls. These real commandos were equipped to conduct a field leaching and concentration of saltpeter, which was then headed in an emergency, to the factories of magazines.
It also created at that time many artificial nitre beds which, like the earth, saltpetre was recovered by leaching, purification and crystallization time.
These nitre beds (described in the former chemical works) requiring several years to produce, we do not therefore include that passage.
The consolidation of farms and the disappearance of cesspools, makes the natural formation of this salt is increasingly scarce, which is good because this scourge literally destroyed the walls that were impregnated, without its it is possible to serve in the final.
The alchemists, fewer than the heyday of saltpetre, still have trouble finding places to procure natural.
When found, [images 1 to 6] it is mixed with other salts, especially calcium nitrate, and ammonia.

When moisture is brought by sea spray, nitrate of soda and sodium chloride dominated. The proceeds of the collection (which has a tendency to decay) will be perfectly dried before sifting carefully [image 7], because it contains a significant proportion of plant debris and minerals, then boiled in the 'water and filter the solution. The suction filter can advantageously [image 8] be equipped with a heater to avoid an early crystallization through filter. These operations are intended to serve your collection of fine insoluble particles.

General remarks on crystallization of purification:
If the solution of saltpeter (salts and other partners) is not perfectly clear, it may still contain organic material in suspension having escaped the filter, it is necessary (for the wine operation is well known collage) to mix a little water fish glue or egg white beaten, then re-filtered.
We must also take care to cool the solution always disturb the crystallization for it produces only small crystals which, once dried, will be quickly rinsed with pure water and very cold. Indeed, large crystals, forming trap always part of the mother liquor that rinsing can not remove. This rinse with water just above zero causes a little saltpetre, but removes twice as sodium chloride.
In addition, and where images of harvest submitted, it will remove the lime grouting stones chemically present in the solution. To this is added potassium carbonate, the reaction product of calcium carbonate and magnesium insoluble it is easier to separate.
This solution is concentrated by reduced crystallization powder dry, kept away from moisture. During crystallization, there has been the appearance efflorescent [image 9] which denounces the presence of sodium salts (Chile saltpetre).
Then you can go through fractional crystallization to remove the accumulating products first. The knack of this operation is optional to stop before the saltpeter does not crystallize in turn.
For the final purification, elders and chemists engaged in major magazines fractional crystallization from a pure seed suspended in the middle of the saturated solution in hot and cooling phase.
We for our part, to use a little known law, (multiple saturation). Indeed, a saturated solution of a body can be a second, third, etc. .. to infinity, until it becomes thick, which is almost the case of the Dead Sea.
The method, which seems obvious, however, asks to be performed with consideration always keeping in mind some important data:
If a solution is saturated with salt, saltpetre deli [image 10] in our case, and we add a mixture of salts (without excess) it absorbs all but the same chemical formula as that which It has previously been saturated. It is therefore only table without mixing. This will obviously be that the temperature does not vary, or very little.

On the one hand, the dissolution of saltpeter in water is endothermic, is saturated pure water, heated to 40 ° C with pure chemical saltpeter for the sausage, which was tested by a quality test crystallization [image 11]. We let the mixture return to room temperature and thus make a little saltpetre [image 12] on the filter and let the moment this solution at rest.
On the other hand, from the powder obtained above, from our harvest, we reserve an amount of weight around that saltpetre chemical used for the previous solution.

Comments about the forthcoming operation:
If we add our brutal saltpeter not pure in the prepared solution, cool it and then deposit the saltpetre (chemical or otherwise) and redissolve part without distinction, while returning to room temperature.
If we heat the solution before it dissolves impurities and part of our saltpetre, for, return to the lodge atmosphere the same quantity of saltpetre, but whose origin is unknown.
In both cases opposed, the result being the same, he must outwit. For this, we must sacrifice a small part of our saltpetre. It adds 3 to 5% water solution prepared for the desaturate it continuously monitors the temperature and it is sprinkled (by very small quantities) of our impure nitre. Initially, a small portion is captured by the added water and the rest will be deposited. This provided the solution never goes below the atmosphere.
Deposits must be sufficiently spaced in time for thermal equilibrium is not broken. If we seek to separate the impurities of saltpetre, (not prohibit the mixing of two different origins saltpetre) there would be no problem.
It retrieves the filing, it drained and it ensures a slow crystallization test of its purity. It was ultimately a canonical saltpetre just go through a chemical filter.
The solution is reusable until (the test will show) that a saturated salt regarded as an impurity, it is no longer able to capture.
This old used solution, with saltpetre from chemical impurities and all will be extensive water and serve as fertilizer to your lawn.
Another possibility is to make canonical saltpetre trade by placing it in prolonged contact with animal matter, ie manure or human urine (not sip of drugs). And trying to imitate it in the operation of a nitre beds, let them form blooms of nitre to the surface of an artificial porous wall.
A single brick of 50 x 50 cm cut in half and set in mortar [image 13] may receive 6 kg of saltpeter diluted manure [image 14], (check the tightness of the bottom of the brick).
Let the device in air and fog (as nitre beds) but to protect from rain. His only monitoring is to keep it moist inside the brick and add saltpeter to mix urine As harvesting by scraping (the plates that form easily detached) from the surface of the brick.
The control of crystallization can realize [images 15 & 16] the quality obtained.

If obtaining saltpetre of your dreams is possible with a little work and is a very good training in the work of Hercules, it remains to ask a fundamental question: how do you use this pure saltpeter?
The alchemy of chemistry differs mainly because it involves a number of natural compounds whose chemistry strives at all costs to deny.

Preparation of the salts: Sal ammoniac

TP, once you have the Saltpeter what is it used for? Also is it ok to substitute Pottassium Nitrate (KNO3) with Sodium Nitrate(NaNO3)?


10-28-2009, 11:44 PM

Do you have any thought on yourself and the members of this forum who have known this dates in advance? Do you think our experience may be any different? Luke 12:48 comes to mind....

Sounds like a good plan. There can't be enough practical knowledge around here... good with the pics also!

This is from Beuther:

Preparation of Salt of the Earth or Saltpeter of the Philosophers from Virgin Soil ~

In the month of May, when the sky is clear and bright and the air is pure and the weather is still fine, without wind and rain, and lovely odors are everywhere, that is, as it were, lovely odors are rising all around, one should enjoy the early morning and the sunrise, along a beautiful path where the good black earth is so rich, and even more beautiful is the red, the gold, and the red-gold of Nature’s beautiful plants and flowers, which take care to bear in the clover family. The red and gold earth in the mountains of the wine country is also very magnificent. Also even the lime-pit, when you can regard it as more than just sandy. Dig down a few hundredweights, shut yourself apart from one another, so that the stars might well operate therein: This, one should also let lie fallow for 14 days and nights; however, should rain set in, one must cover it well with straw until the weather becomes clear. After waiting 14 days, put the earth in tubs and cover it well. Afterwards, a few tubs should be made, like the silk refiners have, for subjecting the soil to washings with lye (warm water is best) and allow it to stand for 24 hours and then afterwards draw it off, boil it down tone-fourth its original volume, let it stand for a few days, and then open it. It is like saltpeter; it burns, but not much. It is then dissolved, filtered, and coagulated with rain water until complete. Hereafter, it is called Sal Terra (Salt of the Earth) and also Saltpeter Philosophorum (Philosophers’ Saltpeter) or even Sal Natureae Virgineum (Pure Natural Salt) which is dissolved in the seas of the world. The hand is not easily washed.

This is now the high Secretum Philosophorum (Philosophers’ Secret) in which the Universal Spirit of the World is often hidden. It is often called Woman’s Work, since it is associated with soapmaking and cooking.

Sal hoc naturae (Salt of this nature) is thus a unique thing to be considered, since it is actually made up of three different kinds of salt. First, there is a universal salt of the nature of saltpeter and soil, in which the spirit of the world frequently resides. It is not volatile and not completely fixed, but has a middle nature. More than any other, it contains a sal ammoniac, which is actually volatile. And, in the third place, it contains hidden in it an alkali, and a fixed salt. It is also triune, and manifests itself in its subsequent reactions.
