How Profit may be made of the Scoria which remain after this Operation.
It behoveth the studious of Art to know, that there is a difference in the scoria removed from the gold by the forementioned Operations. Those which are removed from the gold only remaining in the test, and in which the Nitre, Antimony, and Copper remain mixt, are metallick, from which the Copper and Regulus may be precipitated and separated, by the casting in of crude Antimony or Powder of Coals. The scoria from which the Metals are already precipitated in the test, are nothing but fixt Nitre. The scoria also differ, in which the Metals are precipitated by Antimony, from those which are precipitated by Coals; those partake more of sulphur, these less; for the sulphur of coals differs in its nature from the sulphur of antimony, and requireth that a difference be observed, and that either scoria being put to its due use, it may bring the desired profit. And this is the difference: When the Copper, with the Regulus-Martis, is precipitated by coals, that the Copper, with the Regulus of Antimony, is precipitated, but the Iron which was in the Regulus admitteth not of precipitation, but remaineth in the scoria; whence it comes to pass, that the Regulus, after precipitation, is found to be lighter than when it was put into the Crucible. Therefore what the precipitated Regulus hath lost, necessarily remaineth in the scoria; for which cause those scoria are of more hard and difficult fusion than those which remain after the precipitation with Antimony: For when the metals are precipitated by the casting in of Antimony, to one pound of scoria, an ounce, and sometimes more, of Antimony, is cast in, which precipitateth all the Copper and the Regulus attracted by the Nitre, and giveth a more ready fusion to the scoria. But nothing more plainly sheweth the difference, than the pouring of water upon the scoria, to make a lixivium. The scoria upon which the coals were cast, yield a clearer and sharper lixivium than those on which Antimony was cast. On the contrary, the Antimonial Scoria, by reason of the Antimonial combustible sulphur, are of a drier nature and property.
The best thing in both the scoria, is the fixt Nitre, which is to be drawn out of them by Water, and may be put to various uses, with no small profit.
In the first place, from those scoria a good Medicinal Tincture may be drawn by the affusion of spirit of Wine, of which mention is made in divers places of my Writings. Those scoria far excel all Dung, and also common salt-petre it self, in promoting of vegetation. Nevertheless, they are first to be made more temperate, because they are too fiery to be used alone. They also effectually promote the augmentation of Gold, and also the health of the humane body, by their most pure Essence extracted by the spirit of Wine.
They may without injury be called The Philosophick Dung, because they augment the growing power in Vegetables, Animals, and Minerals, neither in Operations of this kind is there any Equal in the world.
Their smell is like that of humane Excrements; nor are they unlike to them in Aspect, but most efficacious in their use. There are many things of great moment yet lie hid in them, all which it is not for me to describe. Those things which I have hitherto written, I have often done with my own hands, and proved by many Experiments. What I deliver is not from hear-say, or the reading of others Books, being resolved to publish those things only, which an infallible Experience hath taught me, so that every man may boldly, and without any doubting, give credit to them.
Moreover, this fixed Nitre is endowed with the same virtue with other strong lixiviums: Nevertheless, it is more efficacious than that of any common Wood, inasmuch as Nitre exceedeth the fixed salt of Wood in its maturity. The residue of the scoria from which the lixivium is extracted, serveth for the glazing of earthen Vessels.
He that desireth to know more of fixed Nitre, may find it in my Furnaces, as also in my Pharmac. Spagyric. and especially in [The Explication of Miraculum Mundi]; where he will meet with many things worthy of admiration. For the Philosophick Dung, see the 35 Article of [The Explication of Miraculum Mundi], my [Apology against Farnner], and the Description of my Press for Wood, in this Treatise; in which places he may find those things which will abundantly satisfie him. Concerning this Universal (tho’ contemptible) subject Nitre, we will treat more, God willing, in the following [second part of Miraculum Mundi].
Here we have shewed the well-minded Reader, how by this one only Operation, he may encrease or augment his Gold, inrich his Fields with a fruitful soil, and preserve his health; so that there will be none who may not receive profit from it.
I cannot but here commemorate what some time happened to me in this Operation. When the Copper and Regulus-Martis were mixed by melting together, and reduced into scoria by Nitre, the matter thence proceeding was wonderful, appearing in variety of fair Colours, emulating a Peacocks Tail. Therefore when I saw such various colours, I presently thought with my self, whether that matter might not be fit for making a Tincture, which might change the imperfect Metals into Gold; seeing that I had read in some Philosophers, that there is more Tincture in Iron and Copper than in Gold, which gave me an occasion of considering whether this conjunction of Mars and Venus, might not be the Adultery spoken of by the Poets, or rather the Vitriol of the Philosophers; for this matter retaineth a very fair greeness, not only in the fire, but also out of it, as well wet as dry. Whence I began to perswade my self, that Iron was the Gold of Philosophers, Copper their Luna, and Antimony their Argent-vive, and Nitre to perform the Office of a Solvent or Bath, in which they are dissolved and digested. Being moved with all these things, that I might make a trial, according to my simplicity, I put all the said matters into a Glass, and committed it to Vulcan, (or the Fire) which being administred by degrees, all the matter passed together into a black colour; to which a very fair greenness, with variegated colours resembling the Tail of a Peacock, succeeded, which continued in the fire for some weeks. But seeing that it would not at all be changed, I being wearied with the tediousness, took the fair matter out of the glass, and put it into a Crucible, which I set in a Glass-makers Furnace, that I might perform this Operation with the less Labour: And after three daies I again took it out, and I found all the matter changed into a glass of a bloody colour, but not transparent. The Crucible being broken, I found in the bottom a little Regulus of an Iron-like colour, which being tested with Lead, yielded white Silver, which being dissolved in Aqua-fortis, left no Gold at the bottom. Being strook with admiration, I began to think whence that Silver should proceed, seeing that I did not expect Silver, but Gold; at length being satisfied in that, I was of opinion, that from this subject by one and the same labour, might be made both a red and a white Tincture; but I have not hitherto had time and opportunity to try the truth of the matter experimentally. Whatsoever I have here written, is only that I might afford matter to others who are desirous of seeking, by whose diligent searches some good may be obtained. This Admonition I also think necessary, That they who endeavour to bring any subject to a constancy in the Fire, by fixing, as the Chymists call it, that they lute and close well their Vessels, lest the Air (which is a great impediment to the Operation) should hinder the Work.
