In the first place, it is behoveful for every one to know, that the said Aurum Potabile, when brought to its due perfection, and such as my self know, hath the resemblance of a bright and clear water, is of a burning, hot, and fiery taste upon the tongue, and gives out a sulphureous, but yet pleasant odour.
But some may say, What can any such virtues be in a clear Water? What reason have you to call it Potable Gold, for that ought to be yellow or red? To such an one I answer, That in the whiteness is a redness hidden, which is not discernable in its tender Infancy; but when by the help of the fire it arrives to a greater age, then it discovers it self, and shews forth its comeliness and excellency together with most eminent strength and efficacy: For thus say the Philosophers, Unless you make our Gold white, you cannot make it red. And in another place, If any one knows how to destroy Gold, so as it shall be Gold no more, he hath arrived to a most great Secret. And again, in another place, Our Gold is not common Gold, but Gold potential, not formal (or Gold in power, not in shape). Such Sayings and Sentences the whole Troop of the Philosophers is full of; by which it is exactly demonstrated, that the true Aurum Potabile ought not to be presently red, as to the outward view, but that it merits this Title, if there be but only that golden and red virtue and efficacy lying hidden in its internal principle. For if this whiteness did not cover over an hidden redness, it could never possibly become red. Now my Aurum Potabile being coagulated by the means of fire, and reduced to a stability in the fire, is turned into a stone of a blood-red colour, and yields not in the melting any corporeal Gold, unless a metallick body be adjoined unto it, into which the Spiritual and Philosophical Gold, betakes it self, that so cloathing it self with a body, it may become Corporeal.
This potable Gold of mine is, Lac Virginis, or the Virgins Milk, which is coagulated with a small heat. This Coagulum Passeth into (or becomes) the Dragons-blood, which being coagulated, must necessarily yield the constant or durable Salamander. I confess, that hitherto I have not prepared it; nor had I any opportunity to prepare it, but remain contented with my Lac Virginis, as with a most excellent Universal Medicine, patiently expecting what the Divine Grace will in time to come bestow upon me.
But that I may proceed on to shew that my Aurum Potabile doth likewise heal the Minerals, amend them, and make them golden, I will here set down some waies of doing the same both in the dry, and in the moist way.
The manner of trying (by the moist way) whether or no my Aurum Potabile be a true Philosophical Volatile Gold.
Take of my potable Gold ℥ j. and ℈ j. or ʒ ss. of Common Quick-silver, put them into a strong Glass, and so small, as that it may be half full with this matter. (NB. The glass must have a round bottom, whether it be a piece of some small Bolthead, or of some small Phial, that so the Mercury may gather it self into one Ball in the bottom) and place your glass, with the potable Gold and Quick-silver, in Sand, to the heighth of the Liquor, then heat it, and leave it for about one hour in a sufficient heat, that the Phlegm being exhaled, the potable gold may stay behind in the form of a white Salt: This done, pour agen upon that Salt so much Rain-water as it evaporated in the boiling, or fill the glass so full with Rain-water, as it was before full of the Aurum Potabile, that so lying a while upon the said Salt, it may dissolve it, which is hereby again turned into the same potable Gold, having the same colour, the same taste, and the same virtues as it had before. The Mercury being freed from the said potable Gold, which is to be poured off, is found to be hard, and fix in the bottom like the best gold, and of the same bigness or quantity, as when it was put into the glass. NB. If by some errour committed the Argent-vive be not enough tinged and brought to a due degree, but hath gotten some blackness, it is to be taken out of the glass, and put into some little Crucible, and to be heated red-hot with live Coals, that so it may receive the due golden colour; which said colour it will get, and will be like the best Duckat Gold, and will abide good and firm in all trials. But that Aurum Potabile which was used about the coagulation of the Quick-silver, may be often made use of about the same labour; but yet you are to note, that you alwaies take each time less and less Quick-silver to this operation, because the potable Gold doth in each of those successive labours lose by little and little its virtues.
This way of coagulating of Mercury may be likewise used about the coagulation of other Minerals and Metals, provided that the said metals be reduced into thin Plates or Leaves, and so put in; for being put in too thick, they cannot be totally digested in so short a time by the Aurum Potabile, into the due degree of Perfection, but remain (as their inside part) crude, and therefore an accurate regard is hereunto to be had. If this Labour be rightly done, the Metals will be throughly transmuted into pure and good Gold, and that of the same magnitude, figure, and form they were of when you put them in; but yet one metal is sooner transmuted, and more commodiously than another, according as it shall be of a nearer affinity unto gold. NB. If the Metal be not in a due manner proceeded withal, but be as yet black when it is taken out of the potable Gold, it is then to be well heated red-hot, that so it may get its golden colour. And if there be even yet any doubt left, let him put it in ♃, and purge it by the Cineritium, or the Cupel, that so he may be assured of having true gold, and may be freed from all kind of scruple and doubt; for neither ♃ nor ♁ will take away ought therefrom; which thing the proof it self will most clearly demonstrate.
