Extraction of Plant Salts
Pick at least 5kg of Rosemary (Rosmarinus Officinalis), or of another plant that you choose and dry it in the sun. After it becomes very dry, incinerate it on a sheet of iron.

Gather the ashes from the incineration, place them in an iron frying pan, and set the pan on a gas stove.

Adjust the stove to a very high heat and calcine the ashes for one hour, constantly stirring them with a stainless steel spoon. When the ashes are well calcined they will be a clear grey colour.

Next, pour 750 ml of rainwater into a 1 litre large-mouth flask. While they are still hot, add the ashes to the rainwater, a little at a time.

It is important that the water level is at least one hand's-width above the ashes. Add more water if necessary to reach the desired level. If one flask is not enough to hold all the water, divide the ashes between two or three flasks as necessary. Stir the water/ash mixture well with a glass rod and then let it settle for one hour.

If the ashes have been properly calcined, as our Art demands, the water of the lixiviation will be clear and transparent; otherwise, it will be the colour of tea.

In another similar flask, place a glass or plastic funnel with a small cotton lid. Decant the water of lixiviation by pouring it into the funnel, and when everything has drained, add the ashes to the funnel with a stainless steel spoon. Rinse the original lixiviation flask with a little rainwater and pour it onto the ashes in the funnel. When the whole liquid has been drained, pour some more rainwater on the ashes to extract all of the soluble salt that remains in them.

Pour the lixiviated liquid into a porcelain container and set it in a sand bath, which has been placed in an electric, or gas oven. As the water evaporates, the dissolved salt will begin to crystallize or coagulate, and as the evaporation proceeds further, a film will be created on the surface of the thickening liquid, which will impede the continued evaporation of the water.

Therefore, when the solution arrives at the point where it develops a surface film, we recommend stirring it well with a glass rod, to break-up the superficial layer of coagulated salt.

After all of the water has evaporated, the remaining coagulated salt should be as white as snow. If it is not white, you will have to calcine it again in a stainless steel porringer or pan, with a very strong fire and dissolve it in fresh rainwater once again, following the instructions given above. The secret to extracting the white salt the first time is the proper and complete calcination of the ashes. Do not be in a hurry in executing this operation, because if it is done properly, it will save you a great deal of work.

extracted plant salts

We met an artist personally whose pretension and arrogance was humbled to the degree, which characterises true alchemists. On a certain occasion, we had the opportunity to show him plant salts that were white as snow and coagulated according to the Art. When we told him that it had been extracted from the first calcination, he didn't believe it, even though he proclaimed wisdom of the Art and had never accomplished this on the first crystallization.

When we revealed to him the modus operandi, he remarked that we burned the sulphur of the salt! It goes without saying that this answer demonstrates a gross ignorance of the Spagyrical Art.

Although this fixed salt is primarily potassium carbonate, it also contains small amounts of other mineral salts that were contained in the plant, and it probably the thick liquid will create contains some oligoelements.

This fixed salt will be necessary, along with the plant's sulphur or essential oil, in the preparation of the First Being of the same plant.

If you intend to obtain potassium carbonate (formerly well known as the salt of tartar) exclusively, we recommend incinerating a large amount of grape-wine tartar, acacia, fern or oak, which are all rich in potassium salts.

If you intend to obtain exclusively, potassium carbonate or salt of tartar, as it was well known formerly, we recommended to incinerate a large amount of grape-wine, acacia, fern or oak, which are all rich in potassium salts.

Following the procedure given above, you will able to extract a beautiful salt of very pure canonical tartar from the crude tartar, which is commonly left as a residue in wine barrels.

Salt of tartar that has been well calcined, is highly deliquescent (i.e., it will readily absorb moisture from the air.) Once it has absorbed some water it's nature is altered, so be sure to store the salt in a well-sealed large mouth glass flask.
