When you have adulterated the _Antimony_ well and purely from the corrosive Water, then put it into a clean Vial, poure good distilled Vinegar upon it, set it forty dayes and nights to putrefie in Horse-dung, or in _Balneum Mariae_, it will be bloud-red. Take it out, and see how much is yet to be dissolved, decant off gently the pure and clear, which is red into a Glass-Gourd, poure other Vinegar upon the _Faeces_ as before, that if any thing should yet remain therein, it might be dissolved; this must be done four times in fourty days and nights; for if any good be in the _Faeces_, it will be dissolved in that time, then cast the Dregs away as unprofitable, being but Dirt, and to be cast to the Dunghill. Put all the Solutions in a glass-Gourd into _Balneum Mariae_, distil all the tart Vinegar from it, pour it on again, or else pour fresh, if this be too weak, it will quickly dissolve in the Vinegar; distil it again from it, that the Matter be quite dry; then take common distilled water, wash all tartness from it with the Vinegar imparted to the Matter, then dry the Matter in the Sun, which is of a very deep red, or else dry it very well at a gentle fire. When the Philosophers find our _Antimony_ thus secretly prepared, they say then that its external nature and virtue is inverted internally, and the internal cast forth externally, henceforth becoming an Oil, which is concealed in its innermost and profoundest part, till it be well prepared, and cannot any more be brought into its first Essence, untill the last Judgment; and it is true, for so soon as it feels the force of the fire, it flies away in a Vapour with all its parts, because it is volatile. Some of the common Laborators, having thus prepared _Antimony_, they take one part out because of its consumption, that they may the better operate it, they mix with it one part of _Salt-Armoniac_, one part of the _Vitrum_ (with others _Titrum_) one part of the _Rebooth_ (with others _Cadoli_) wherewith the Bodies are cleansed; this mixture they cast upon a pure _Luna_, and if there were eight Ounces of the _Luna_, they found ten Drams of good Gold in the separation, and sometimes more; and by this work they gained wherewithal to bear their Charges, the better to attend upon, and attain unto the great Work. The ignorant called this an induction into the Silver, but that is false; for this Gold is not brought into it by the Spirits, but every kind of Silver hath one Ounce of Gold more or less in the Mark (or 8 Ounces) for Gold is so united with the Nature of Silver, that it cannot be separated from it, either by _Aqua fort_, or common _Antimony_, as the _Gold-smiths_ know.
