To make a rare spirit of vitriol.
If common vitriol be dissolved in water, and you boyle granulated Zinck in it, all the metal and sulphur contained in the vitriol will precipitate on the Zinck, and the solution will turn white, the precipitated matter is nothing else, but iron, copper, and sulphur, which the salt of vitriol did contain, and now is drawn from it by the Zinck. The reason why the metal precipitateth out of the salt upon the Zinck, belongeth to the fourth part, where you will find it sufficiently explained; The white solution, from which the metallical matter is separated, must be coagulated to the dryness of salt, and so by it self a spirit distilled of it, which riseth easily, and is in taste and vertue not unlike unto common oyl of vitriol, but only that this is a little purer than the common.
Here perchance many may object: you take the green from the vitriol, which Paracelsus doth not teach, but bids us to keep it. To which I answer, that I do not teach here to make the sweet red oyl of vitriol, whereof Paracelsus hath written, but the white acid oyl; which is as good, or rather much better than the common, which is made of the common impure vitriol. To what purpose is it, that you take green vitriol to distil, whereas the green doth not come over, and although that green should come over, why should that oyl be better than the white? for the green in the common vitriol is nothing else but copper and iron, which the salt water running through the passages of Metals did dissolve and take into it self, and as soon as such a green vitriol feeleth the fire, the green turneth into red, which is nothing else but a calcined iron or copper, which in the reducing by a strong fire and by melting is made manifest.
Paracelsus hath not taught us, that we should drive over the green by the force of the fire into a red and sweet oyl, but he hath shewed us an other way, which is found out by few men, whereof in the beginning of the second part already hath been made mention.
This spirit or acid oyl distilled out of the purified vitriol, is of a pleasant sowreness, and serveth for all those uses, which above by the vitriol were described. And this process is set down onely for that end, that we may see, that when the vitriol is purifyed, that then it is easier distilled, and yieldeth a more pleasant spirit, than if it be yet crude and impure.
And that such a purifying of the vitriol is nothing else but a precipitating of the metal, which the water (as before said) running through the veins thereof hath assumed, is thus to be proved; dissolve any metal in its appropriate Menstruum, whether it be done with distilled acid spirits or sharp salts, adding common water to them, or else dry by the fire in a crucible, according as you please, and then put into that solution another metal, such as the dissolvent doth sooner seize on, then upon that which it hath assumed, and then you will find, that the dissolvent doth let fall the assumed metal or mineral, and falls upon the other, which it doth sooner seize on, and dissolveth it as being more friendly to it; of which precipitation in the fourth Part shall be spoken more at large.
This one thing more is worthy your observation, that among all metals there is none more soluble than Zinck, and therefore that all the other (as well in the dry as in the wet way) may be precipitated thereby and reduced into light calxes, in so much that the calx of gold or silver precipitated in this manner (if so be you proceed well) retaineth its splendor or gloss, and is like a fine powder wherewith you may write out of a pen.
To make a subtle spirit and pleasant oyl of Zinck.
Because I made mention here of Zinck, I thought good not to omit, that there may be made a penetrating spirit and wholesome oyl out of it by the help of vinegar, which is thus to be done. Take of the flores (which were taught to be made in the first part) one part, put them into a glass (fit for digestion) and pour upon them 8, or 10. parts of good sharp vinegar made of honey; or in want thereof take wine vinegar, and set the glass with the flores and vinegar in a warm place to dissolve, and the solution being performed, pour off the clear, which will look yellow and after you have filtred it abstract the phlegm, and there will remain a red liquor or balsome, to which you must add pure sand, well calcined, and distill it, and first there will come over an unsavory phlegme, afterward a subtle spirit, and at last a yellow and red oyl which are to be kept by themselves separated from the spirit, as a treasure for to heal all wounds very speedily. The spirit is not inferior unto the oyl, not only for inward use to provoke sweat thereby, but also externally for the quenching of all inflamations, and doubtless this spirit and oyl is good for more diseases, but because its further use is not known to me yet, I will not write of it, but leave the further tryal to others.
