Spices, seeds or flowers being extracted therewith and digested and distilled, the essence of them will come over with it, in the form of a red oyl.
Vitriol of copper.
If you pour it upon calx of copper, made by often heating the Copper red hot and quenching it again, it will extract within an hours time a fair blew colour, and having dissolved as much thereof as it can pour it off and let it shoot in a cold place, and you will get a fair sky coloured vitriol, a small quantity whereof will cause strong vomits; the rest of the vitriol remaineth a blew oyl, good to be used in ulcers.
The Tincture of crude Tartar.
If you take common crude tartar, and pour of this spirit upon it, and set it in digestion, the spirit will extract a blood-red tincture, and if the spirit be abstracted from it, there will remain a pleasant red oyl, of no small vertue and power.
To make the oyls or liquors of salts.
This spirit also dissolveth crystals and other stones, they being first dissolved, precipitated and reduced to impalpable powders, turning them into oyles and liquors, good to be used in Alchymy and Physick.
To precipitate all metals with it.
Any metal being dissolved in an acid spirit may be precipitated better and purer therewith, than with the liquor of the salt of tartar; for Aurum fulminans which is precipitated with it fulminateth far stronger than if it were done with oyl of tartar.
R. Some juyce of Lemon and mix it with the solution of gold, before it be precipitated, and then not all the gold will precipitate, but some of it will remain in the solution, and in time many small green stones (not unlike unto common vitriol) will appear; which in a small dose will purge all noxious humors.
