Another way of separating the superfluous Antimonial Sulphur,
℞
Antimony powdred one part, Salt-peter half as much, mingle them, and kindle the mixture with a live coal, and let that Antimonial sulphur, with the nitre be burnt up, the darkish mass being left, to wit, of a brown colour; which melted for the space of an hour in a strong fire yeilds an Antimony like to that which is made with salt of Tartar, but somewhat less in quantity: in like manner the parts of Antimony are separated, viz. if Antimony, Nitre, and crude Tartar be mingled in an equal weight, and being mixt are kindled and melted. There is also another separation of the Antimonial parts; when of small bits of Iron one part is pat into a strong crucible, in a wind Furnace, to which being red hot, cast two parts of ground Antimony, for fusion, and the superfluous combustible sulphur will forsake the Antimony, and joyn to the Iron, a metal more amicable to it; mixt with which, it forsaketh its own proper pure Mercury, and sulphur or Regulus, which is almost the half part of the Antimony.
And these four ways, by which the superfluous combustible sulphur of Antimony is separated are most common, not set down as secrets, but for demonstration sake, that it may appear how sulphureous minerals are, to be perfected and purified, which are little amended; yet shewing a better way not only for Antimony, but also for Arsenick and Orpin, although these two cannot be so done with Iron, Nitre and Tartar, by reason of their volatility; but with Oyl, or other fat things in close crucibles, giving a Regulus like to the Antimonial; and these Reguli make Tin hard, to sound and be compact; if to one pound one ounce be added in fusion, for making good houshold stuff. And in tryal they give good Gold.
And as it is said of purging Antimony, so also it is to be understood of the rest, as Wismuth, Zinck; Lapis calaminaris, Lead, Tin, Iron and Copper, to be purged from their superfluous sulphur, if thou wilt draw more perfect metals, viz. Gold and Silver out of them with gain. And so I make an end of metallick lotions; recommending to Chymists, Nitre, Tartar, Flints and Lead; for who knoweth to use them, shall not lose his labour in Chymistry; but ’tis to be lamented, that every where good earth and fixt in the fire, is not to be gotten, retaining Lead and Salts; for without our old Saturn little or nothing can be done in refining metals; therefore who goes to try any thing in this Art, let him seek the best earth retaining Lead twentyfour hours space; afterward let him consult with Tin, what Vulcan has to be done with Iron; who will tell him what he must suffer, before he obtain the Crown.
Of the tincture of Sol and Antimony.
Sometimes an alteration happens to mans body, from the attraction of mineral vapors (which cannot be done by my Furnace) in the tryal; therefore here I will set down a certain medicine for the Workmans sake, as well for preserving as curing, namely, a clear rubin fixt, and soluble of Gold and Antimony. Take of pure Gold half an ounce, dissolve it in Aqua Regia; precipitate the solution with liquor of Flints, as before is said in the Second part; edulcorate and dry the calx, and it will be prepared; take Regulus Martis (of which is spoken a little before) beaten fine, to which mix three parts of the purest Nitre; place the mixture in the crucible between burning coals, putting to fire by degrees: which done make a stronger, viz. for fusion; for then the Mass will be made purple; which taken forth and cooled grind very small, of which take three or four parts and mix with one part of the aforesaid golden calx; place it mixed in a strong crucible covered over in the aforesaid winde Furnace, and make the mass to flow together like metal, and it will assume the Antimonial Nitre in the fusion, and will dissolve the Gold or the calx of Gold, and a mass of an Amethyst colour will be made therewith, which so long leave in the fire, till it get the clearness of a Ruby, which one may try with a clean wire or iron bowed and put therein, although the mean time the mass deprived of fusibility, is thickened; it is meet to add some Nitre or Tartar, for speeding fusion, and that as often as shall be needful. Lastly, pour the mass, when it shall come to the utmost redness of a Ruby, hot into a clean copper morter, which there leave until it cool, and it will be in colour very like to an Oriential Ruby; then bruise it hot into powder, for taking air it would melt, and extract the tincture by the affusion of the spirit of Wine in a Vial, and the Gold together with the Antimony will remain very white like the finest Talc, to be washed with clear water, in a glass, edulcorated and dryed; which melted with a stronger fire, gives a Yellow glass, in which no Gold appears, yet separable by way of precipitation with the filings of Iron and Copper, from which it recovers its ancient colour, but without profit, by reason of the wast, the tinged spirit is to be taken away from the tincture, which is a very soveraign medicine in many grievous diseases.
Although thou mayest suspect this not to be the simple tincture of Sol, but of Nitre and Tartar mixt, be sure that the quantity of Nitre added not to exceed; and suppose that tincture of Tartar and Nitre, I pray what waste is there? since that is so good a medicine by it self, & I am perswaded, this tincture of sol to be better than those set down in the Second part. That Ruby may be so used by it self with proper vehicles, seeing it is a soveraign medicine of it self; or else exposed to the air and resolved to a liquor; for the medicine is no less than a tincture, because the Gold in it, and the purer part of Antimony are made potable without corrosives. Wonderful is the power of salts in metals to be destroyed, perfected and changed by fusion; for it happened to me one time making this Ruby, placeing two other crucibles also with metals, by this containing gold with the prepared Regulus of Antimony (for easily two or three, or more crucibles may be placed in this furnace, to be ruled with one fire, which cannot be done in a common furnace by that means) about to put in a certain salt into the crucible next to the crucible of gold, that by a mistake I cast it into the crucible with gold only, whence so great a conflict arose, that there was danger of boyling over; therefore forced to remove it out of the furnace presently with tongs, and to effuse it, supposing that the Ruby was left by my rash putting in of salt; therefore I would only save the gold. And I found the effused mass red like blood, purer than a Ruby, but no Gold; but white grains like Lead dispersed here and there in the salts, by reason of their smalness, not separable but by the solution of the salts, which being separated by the solution of water from the red tincture like blood, remained in the bottom of the glass, which afterward for fusions sake I placed in a new crucible in that furnace, but willing to try the fusion, I found the crucible empty, and all the Gold vanished, a little excepted sticking on the top to the crucible and the cover, which I took away and melted for experience sake in a new close crucible, but all of it presently feeling heat flew away like Arsnick, no sign being left in the crucible; and so I was deprived of my Gold.
At length I took the red solution, and abstracted the water from the salts, and I found the salt red like blood, which I put in a clean crucible in the furnace for to try whether any metallick body might thence be extracted; but I found the effused salt deprived of all tincture and redness, which seems strange to me even to this day, that by help of this salt the whole substance of gold, viz. the tincture together with the remainder flew away, having so great volatility.
Which labour afterward I would reiterate, but it happened not so at all as at the first time; there was indeed some alteration of the gold made, but its volatilization was not so great, the cause of which thing, I think was the ignorance of the weight of the aforesaid salt, cast in at the first time against my will.
