Nevertheless, you may also at your pleasure render metals brittle and frangible, viz. By the help of the Regulus of Antimony, so that they may be pulveriz’d, then pouring your Menstruum upon them, dissolve, digest and convert them into Medicine: Which method is certainly good; You may also proceed another way with metals prepar’d by Antimony, viz. Mix them with three parts of pure Nitre, and in a Glass or earthen vessel, by the dry way dissolve, digest, fix, and by spirit of wine prepare into Medicine, which also will be good, for it is more profitable to operate by the dry than by the moist way, as it is customary to be done in vegetables and Animals.
And this is the shortest method of reducing Animals, Vegetables and Minerals by the Alkahestick liquor to the best Medicaments.
But how imperfect metals or Minerals, which otherwise in a Cupel or Cineritium trial, leave no gold or silver behind them, are to be brought to maturity and fix’d, that afterwards in the Cineritious trial, they may give a perfect gold and silver is done another way, whose process is this:
Mingle and melt so much (Regulus) of Antimony with the imperfect metals or minerals as may render them friable, that they may be pulveriz’d, with these mix three parts of the purest Nitre, and this mixture close stopt up, put upon a fire in glass or earthen vessels to fix for some hours, afterwards take it off, and as they are melted pour them out, that they may give the regulus which is to be taken away, and with lead put into a Cupel and reduc’d to dross, then that gold and silver which the imperfect metal or Mineral got in the fixation, stays in the Cupel which may be examined by the lesser weights of probation, whence it will appear how great a fixation so little time will produce.
This is the plenary and fundamental instruction of the use of Tartar purg’d by flints, to extract the essence of vegetables and animals and of Nitre fix’d by coals and Regulus of Antimony, which begets a penetrating, correcting, bettering or ripening and purifying fiery, but not corrosive, virtue, which goes beyond all things, penetrates and corrects as above written, I have attributed to it. But least the ignorant of natural things should esteem and proclaim this a corrosive liquor, we will prevent them, and shall endeavour to demonstrate, that this liquor is no way a corrosive, but an enemy to and destroyer of all corrosives.
Like loves its like, with it is mingl’d, and immutably stays with it, as may be seen in spirit of Salt, Vitriol, Alum, Nitre, Vinegar and other corrosive spirits when they are mixed. But unlike things if they are join’d, are contrary to themselves, and fight against each other, and forcibly withstand one another so long, till the strong o’er comes the weak and kills and destroys it or produceth another substance from it: that may be seen if this fiery liquor of Tartar or Nitre be mix’d with a corrosive Spirit, for it can not consist with it, because contrary to it, then which of these is the stronger, destroys the weaker and takes its nature to it self.
And this difference arises from the unlikeness of the nature of either liquor, for one corrosive does not destroy another, as also one fix’d urinous liquor does not destroy another urinous liquor; because one contrary fights against another contrary, but not against his like, so ’tis true, as hence may be fully demonstrated, that this fix’d liquor of Tartar or Nitre is not corrosive, but only a fiery water and a perpetual enemy to all corrosives, and both kills and takes away their corrosive faculty from them. But some will say that the corrosive Spirits of Salt, Alum, Nitre, Vitriol and such like are fiery waters: I confess it, but yet with this distinction, those Spirits are indeed hot waters, but not vivifying, but rather cold and killing fiery waters, which no way ripen, purge or correct Vegetables, Animals and Metals, but destroy and kill all things they are mix’d with. But the fix’d liquor of Nitre or Tartar is contrary, and ripens, purifies and brings to perfection all it is mix’d with, which is impossible to all corrosives, whence it is as clear as the Sun, that it is no destroying corrosive, but a correcting fire.
Now follows another Clause of Farnner’s Epistle.
2. All Mineral’s and Metals.
I much wonder that Farnner was not afraid to offer this process to others at a price, which is plainly and clearly described in many places of my Books: and is done only by Nitre, by which sulphurous metals (but not all metals and minerals, as he vainly boasteth) are reduc’d to dross, from which by spirit of wine, a metallick tincture may be extracted, as we have shewn above in the tract of the Alkahest: that dross is truly fiery, and therefore easily attracts air, and is turn’d into oil, of which I have largely treated in the second and fourth parts of (Furn.) and in the mineral work especially in the explication of the wonder of the world, as also in my Hermetic Colloquies.
