Such likewise is the nature of Metals, touching the propagation and encrease of which their proper seeds and roots are requisite. What I pray are those Tinctures, (one onely particle of which and that no bigger than a Pea, being cast on an whole pound of Tin or Lead, transmuteth that same Metal into pure good Gold, and changeth and augmenteth it self (as being the true seed of Metals) a thousand fold, out of so gross and earthly a body into so noble and so golden a nature in so short a space of time,) what (I say) are those Tinctures, but the very seeds of Metals, and the very metallick roots. But by what means they are to be obtained, and to be brought under a Man’s power, for my part I do not know. But yet I could not but deliver my simple opinion and conceptions concerning this thing, to the studious of Art.
’Tis certain that all Metals have their rise out of one and the same Seed, but that they differ so very much amongst themselves, and that one becomes more ripe than another, is to be imputed to the diversity of accidents. In one and the same Tree are produced Blossoms, and small Fruits of an unpleasant tast; then afterwards bitter and immature ones, and at length ripe and sweet ones, and are not alike either in form, odour, or savour, nor are they of like effects, and yet do they all arise out of one beginning, viz. out of their Seed and Root. So is it even with Metals.
For as touching their Seed I do verily believe, that if from the most soft and as yet most immature Metals, such as Zink, Lead, Tin, Antimony, Bismute, Cobolt, &c. their stinking combustible and superfluous Sulphur, could by some Bath or other be so taken away, as that nothing may remain save onely a most pure Mercury, that then I say such a Mercury, or such a Seed of Metals may be easily transmuted by pure Gold, as being the most pure Root of Metals into a true Tincture.
But to turn common Salt into Salt Peter, the operation is thus.
Take one part of black or of any other common Salt, and mix it with two or three parts of Calx-vive being reduced into Powder by lying in the Air, and lay it in such a place as lies open to the Air and Sun-beams, but yet keeps off the Rain, as we have taught in the Appendix.
Moisten this heap with the above said Lixivium of Salt Peter, and being dried, repeat the moistening and drying so long, untill the ferment shall have converted all the common Salt and turned it into inflamable Salt Peter, the which doth either sooner or later happen, according as the operation hath been the more diligently or negligently handled. All being turned into Salt Peter, let an extraction be made with common Water, as the usual custom is, and lay the Reliques in the aforesaid place, and again moisten them with the said Lixivium as afore, or in defect thereof sprinkle them with common Water, still moistening them after each drying, untill there be a new encrease of Salt Peter begotten, the which you are to wash off with common Water. And so this operation proceeds, or holds on even to infinity.
XXIV. Another far more compendious way of converting common Salt, by the help of fixt Salt Peter into excellent Salt Peter.
Mix some certain weight of common Salt dissolved per se in common Water, and as much of fixt Salt Peter likewise dissolved in common Water, mix them in a wooden Vessel; in which Vessel the fixt Salt Peter being as it were a ferment will seize upon the common Salt, and turn it by fermentation into excellent Salt Peter.
He that desires a more mature Salt Peter may instead of the solution of common Salt, pour upon the fixt Salt Peter Lixivium, those sharp waters of Salt Peter, which have already been used about other labours, and they will seize upon that Lixivium with a more vehement operation, so that of both the solutions as well the acid and spiritual, as the fixt and corporeal Peter, there will be gotten in a few hours space, the most excellent Salt Peter and such as cannot be by any other way whatsoever purchased.
N. B. If any one has a mind of getting a greater quantity of Salt Peter, he may first dissolve his common Salt in the sharp Water of Salt Peter, and [mix it] in that self same Lixivium, [viz. of Peter,] and after the mixing of these two contrary solutions evaporate the common Water, that the Salt Peter may shoot into Crystals, of which there will indeed be a greater quantity, but then it will not be so good as that which was made by the first operation.
