But true potable gold is not so only in name and shew (as are divers waters tinged with a yellow or red colour) but also endued with golden faculties and vertues, so that it may actually appear to be made of gold, but irreducible by Fire into Gold, spiritual and penetrative, strengthning the vital spirits, that they may overcome their enemies. But it must also be endued with this Vertue, that it may change imperfect metals, chiefly Mercury, Lead, and silver into pure gold; not truly like a fixt tincture, tinging with profit the baser metals in flux; but only perfecting particularly in a moist way by digestion, where some part of the metal alone is turned into better. For this tincture of salt or gold is very volatile, so that it cannot resist the fire; but with a gentle heat it melteth like wax, and is sublimed like red salt, soluble in spirit of Wine, that it may be fit for Physical uses. Also true potable gold being tasted, is neither corrosive, nor astringent like other solutions of gold: neither doth it pollute the hands, the nails and hair with a black or yellow colour, but rather makes them more fine; neither doth it infect copper, tin, lead, with rust or a black colour, but rather makes them more clear; neither is it a body of gold reducible by extraction, nor into white gold, which may recover its former colour by Antimony, and _Aqua Regia_, but it is like an ashy earth, and sublimable in a gentle heat like Arsenick, not enduring the tryal of the cuple, which vertues if it have, it may be called the true Tincture of Gold: but if not, not so, but rather a sophisticated potable gold, not to be medled withal. _Of the medicinal use of this golden Medicine._ We have before demonstrated the sun to be the original of gold, or endued with the incredible vertues of the terrestrial sun. For the strength and vertues of all vegetables, animals and minerals lie hid in it; which cannot be manifested but by a Philosopher, and that by separation, to wit, of the intrinsical and pure parts, from the impure. This speech will happily seem to thee incredible, or not very likely to say that gold is reducible into a spiritual essence, agreeable to humane nature, endued with the strength of all animals, vegetables and minerals. Surely thou shalt hardly perswade him whom _Vulcan_ hath not made a Philosopher to believe it. But who will trouble himself so much as with sure reasons to decide all Controversies, which if possible, yet for many reasons is here omitted; but for sureties sake I will send back the Reader to the second part of our Furnaces, where he shall find how out of Antimony and Sulphur, by a good Chymist, with the help of fire, may be drawn not only the force and faculty of divers vegetables, but also their natural odour; which yet did not appear in them before they were radically dissolved, which if it may be done by any imperfect and fetid mineral, why not also by a perfect and mature mineral?
