How from Gold its Tincture may be extracted by help of a Magnet.
Recipe of most pure Gold an ounce and a half, and of the Stellate Regulus of Antimony made with Steel, one ounce, both which melt together in a covered Crucible; and whilst in flux cast at times a little Salt-peter, until the Niter shall have extracted all the Regulus of Antimony from the Gold, and turned it into Scoria’s. Permit the whole to flow well for some time, that the Gold may well settle to the bottom from the Scoria, which will flow like water. Then pour all out into a Cone, where the Gold becomes a Regulus, which must be separated from the Scorias. This Regulus of Sol comes forth much paler than it was before. If this pallid Sol be again melted with the aforesaid Martial Regulus, and the Regulus thence abstracted by the help of salt Niter, the Gold will come forth a little paler than it did the first time. If you repeat this Operation 8, 10, or 12 times, you will find your Gold at length almost totally white, and that its Tincture is extracted from it by the help of that Regulus. The Tincture of Sol is absconded in the Scorias; this, by the benefit of a certain Antipathetick Salt, will be precipitated from the Fæces liquified, like a Regulus highly tinged.
Note: Yet in these Cases, the Precipitation must be warily handled, lest you also precipitate the Regulus [of Antimony] together with it, and so vitiate the Tincture. For this Extraction no vulgar Regulus is conducent, but such onely, as is made of good Steel, and hath such a property, as when a Flint is strook upon it, it yields fiery Sparks, no otherwise, than as from hardned Steel. Which vertue, if it hath not, it cannot rightly draw to it self the Tincture of Gold, but all endeavour will be in vain. This Extraction, Cosmopolita, in his new Chymical Light, hath very well described and discovered in these words. Such Chalibs must be taken, as is endewed with power of extracting that from the Rays of the Sun, which many have sought, but few found. But further he saith: There is found yet another Chalibs, which from Gold extracts its Seed (if it be united or copulate with it 12 times) and thence is impregnated; but the Gold is infirmed even to death. But the Chalybs or Magnet brings forth a Son, which will be more excellent than his Father, viz. Gold, whence he proceeded, whosoever knows this Magnet (of which Cosmopolita makes mention, and an hint of the preparation whereof I have here shewed) and understands how to use the same, in two or three Days he will behold and find so great things, as with the joy thereof his heart will be satisfied. For, if any one hath Philosophick Eyes, he will see what is most pleasing, if not, he will be no more delighted than a Swine, who among the Sweepings of Vineyards hath swallowed an inestimable Pearl or Jewel, but knows not the difference between a Pearl and that Dung.
