Take of my potable gold, or Lac Virginis, ℥ j. and put it in a glass dish; which done, and the dish placed in sand, evaporate all the humidity, until there remain about almost half an ounce of white Salt; put this Salt in a Crucible, with ℈ j. or ʒ ss. of the Plates of Silver, or Copper, or Iron, for Tin & Lead need not be laminated: Place your Crucible, together with the Salt and the Metal, amongst Wood-Coals, and the Salt will presently melt like Wax, and penetrate all the whole Metal, and transmute it into gold; and this operation is done in one quarter of an hour, or half an hour at the utmost. The molten Salt being poured forth out of the Crucible, you will find in the Same Crucible the Plate of the Metal, of the same quantity and shape it was of when put in, and throughly transmuted into pure good gold. The Tin and the Lead will be molten into Granes, as being of easie fusion, which Granes will have the nature of pure good gold. If the Crucible should be too much heated with too intense a Fire, it may also happen, that even the ☽, Copper, and Iron too may melt into granes. And this I thought good to inform the Studious of.
These (O thou Lover of Arts) are the too Examens and Proofs of my potable gold, and of trying it both by the dry and the moist way, which if thou shalt rightly perform, thou shalt not erre from the mark. But now I must needs confess, that this Transmutation is not gainful, and I have already said before, that my divulging of all these things is only to this end, viz. visibly to shew the possibility of the Art. For although that the gold gotten by these proofs be true, and purely good, and passing all the usual Trials, yet nevertheless it brings no profit, because this Aurum Potabile requires so much expences, (afore it arrives unto this degree of power) as that the gold gotten by the benefit thereof, cannot countervail the same. Nay, if it should be somewhat profitable in this way, yet would that man do much amiss, that should waste away and imploy so kingly a Medicine for the getting of a little Gold, seeing there are other waies to get Gold by. And verily, it would be a great sin and shame for a man to consume such a most excellent and eminent Medicine for little mony’s sake. Neither is it for this end, that I have thus mentioned what I have here said, viz. to use it about the making of Gold; for my aim is only this, that all the world may see that there are men to be found, even at this very day, upon whom the Divine Grace hath bestowed the Art of preparing and making most excellent Medicaments. I do not envy, that other men should learn something out of my Writings, and take the opportunity of advancing this Work to a farther perfection: But I would not have the impious ones at all to perswade themselves that they shall obtain this Instrument to do evilly, and to exercise their wickedness by God, who knows what He has to do, will not do those things which are (perhaps) liking and pleasing to our fancies. I can every hour demonstrate the truth of what I have written, with which demonstration I rest satisfied.
I can easily conjecture that various men will pass various censures upon my Writings, but this is what I am not able to prevent; nor indeed do I much care, but I do herein comfort my self, in that I have written an undoubted Truth, and can defend it even before the whole World. I can withal readily guess, that some or other may object against me, and say as followeth, viz. That my Potable Gold is a bare solution of common Gold, which being adjoined unto the other Metals, is by them precipitated, and so reduced into its former body; and this cannot be said to be a true transmutation of the Gold. To refel this objection therefore, I demand, Whether or no the common corporeal Gold can be dissolved without some corrosive Liquor? For this Aurum Potabile of mine is void of all corrosion, and is a fiery water, most extreamly contrary unto all corrosives: Seeing it is nothing else but fixed Nitre, or a sulphureous Salt, betwixt which Salts verily, and common Gold, there is no familiarity at all; nor are there any such virtues therein, as to dissolve the Gold: But put Case it could so be, that the body of common Gold should be dissolved with those fixed Salts, and that by such a Solution it should dissolve (or make) my Aurum Potabile, verily it would necessarily follow, that such a solution of Gold would be of a yellow or red colour. But now ’tis not so with mine, for my Aurum Potabile is so clear and bright, as that it far exceeds the bright transparency of even Fountain-water it self: Besides too, the solution of corporeal Gold tingeth the hair, hands, and nails with a black colour; but on the contrary, my Potable Gold does not so at all, and therefore justly and deservedly, it both may and ought to bear the Title of Philosophical Gold; for all the Philosophers that have been true Possessors of an Universal Medicine, do confess in express words, That their Gold, or the solution thereof, doth not at all colour the hands, by which Character and Sign they distinguish betwixt the vulgar and philosophical Gold.
From hence it necessarily follows, that my Aurum Potabile is prepared of the true Philosophical Gold, seeing it does not tinge the hands with any colour.
But put case that a Solution of common Gold should be made by the help of some menstruum that is not corrosive, (but such is not my solution) yet notwithstanding, it would not throughly tinge the Imperfect Metals and common Quick-silver in digestion with them, and transmute them, but would cover over (as it were,) their Superficies only with the colour of the precipitated Gold, like as is wont to be with all other solutions of Gold, and such a powder performing the same effect, may be prepared of common gold; the way of the Preparation thereof I have delivered in my Writings. Silver being therewithal laid over, is as well gilt, as if it had been done with Gold and Quick-silver: The superficies therefore is only gilded over, but the body of the Silver it self is not at all transmuted, but abides in its former state. So Gold dissolved in spirit of Salt, doth, by the help of the Vitriol of Venus, gild over the Superficies of any Iron, but the Iron retains its Irony property and nature: If to such a solution plenty of Water be poured, and Argent-vive, Tin, Lead, Iron, or Bismuth, be put thereinto, the gold is wont to precipitate out of the corrosive water, in the form of a porous Sponge, and to adhere to the metal thereinto put. Now, as soon as ever the water is shook about, the precipitated gold disperseth it self abroad in the water, like a troubled muddiness, and the Metal is the same as it was before putting in, without any transmutation at all.
Moreover, if any Solution of common gold could tinge the whole body of the imperfect metals (but yet this can never be) it would necessarily gild over the external superficies of the Metals, and especially the external superficies of pure Luna, when rubbed or smeared over with the same; and even this now my Aurum Potabile does not do; but if it be smeared upon Silver, it colours and paints it with all kinds of colours, and as infinite as appear in the Peacock’s Tail, and in such wise too, as that they cannot be easily rubbed out; and these Colours are an undoubted Argument, that this my Aurum Potabile is not the vulgar Gold, but the Secret Gold of the Philosophers.
All these, and other the like Objections, I could most easily prevent by due and fitting Answers, if they should be objected against me; but I think no body will be so audacious, as (without producing any better things) to oppose himself against those things which in the judgment of the whole World are accounted for good.
Of the Use of my true Aurum Potabile in Medicine.
To what purpose should I make many words of the most great Efficacy and Virtues of my Potable Gold in Medicine? I do not deem it a thing necessary to write a large Book concerning them, for such kind of Writings do many times more hurt than good: For there is such an odd custom of Writing so prevalent, as that some men blush not oft-times to ascribe such great virtues to some coloured Brandy-wine, as can hardly be attributed even to Aurum Potabile it self. I confess, that many times there lies more Virtue in some very vile mean thing, than in precious and sumptuous Pearls.
