Without doubt he aimed at our good, supposing he had written very clearly, and directed his speech in such a manner, as if he had to do with one that is skilful in the metalline nature, without having any respect to the common blindness and ignorance, whereby he received great thanks, and was highly esteemed of by all.
But what shall we say or do? ’Tis bad meeting with wicked proud men, as thou most clearly writest; yet because the unexercised, if they have even once erred, they wrack and abuse the Writer with meer slanders: Hence it comes to pass, that many desire rather to be silent, and leave unto fools their own toys and vanities: But the Case being with more accurate examination considered, it seemeth evil to be revenged on the Innocent as well as the Guilty.
As for Tin, if thou searchest into its nature and property, it is a pure (compared with the other metals) unripe metal, abounding with very much combustible Sulphur, whereby it obtains its liquifaction and corruption in the fire: which being removed (and it may be done with a gentle fire) it loseth its metalline fluidity, and very much resembles unmelted ashes, whereto if you add another sulphur, whereby that ashes may turn into a metal; and again convertest it into ashes, repeating this labour until all its combustible sulphur being burnt up, it refuseth to go into ashes, by Calcination, and then melt it, ’twill easily give forth its gold and silver in the trial (im abtreiben.) Now, in the being mixt with Lead, it causeth a strife in a strong Fire, and getting uppermost, turns into ashes, that is to be imputed to the combustible sulphur, whereby it so being melted with Gold, Silver, Copper and Iron, it makes them brittle like to Glass, but being dispelled of that Sulphur, by roasting or calcining by Incineration or Cementation, or any other way, it doth not any more make them brittle (which thing to do is full of difficulty) but is melted with them, and most easily separated with, Venus (last sich sehgern) she knowing how by her kind and flattering words to perswade the two old men ♄ and ♃, mutually to abide each other in the fire; Gold and Silver will also do the same thing; but because they are precious and easily flow out of the Crucible, and the Work may perish, it is sufficient to use ♀, which also will give from it self its own hidden Gold and Silver, and not to take these metals which are purified with great labour, and drown them afresh in impure metals, and destroy them.
There are also other waies of purging ♃, from his superfluous sulphur, viz. a Nitrous fire. If filed ♃, being mixt with Nitre, Sulphur, & Sawdust, be kindled, part of the tin is elevated up into flores, and a part remains reducible in a strong fire, which is to be so often handled the aforesaid way, till all the substance be reduced, into flores and ashes, the metallick form and nature being most plainly destroyed; after this, let the flores be gathered out of the Receivers, and the ashes elixiviated or washed, and by the help of a good Flux be reduced into a metal, which is to be again filed, sublimed, and burnt, as before, until all the Tin remains like Scoria, and will not sublime; which being melted with Lead and separated, (mit Blen amstieden und abtreiben) thou shalt find gold and silver shut up in its bowels.
Likewise pour fixed Nitre (the liquor of it) on the filings of Tin, digest it its time, supply the evaporating moisture with new Liquor, that it may be alwaies moist, but yet let it not be too wet, but like thick water. This Liquor dissolves and takes away the combustible sulphur of the Tin, and fixeth that which is incombustible, and makes it capable of enduring the fire; so that being melted with Lead, and purged (aensieden und abtreiben) it yields its gold and silver.
Another separation is thus instituted; Reduce Tin with common ♄ or Regulus, ♁ j. into Glass or Amausa, which keep a good while in Flux in a strong fire, (forget not the inceration of Nitre or salt of Tartar) by which labour the purer parts of the ♃ being gathered together, do give a Regulus, the impurer parts separating themselves with the Lead and Salt into Scoria, the Regulus being purged (abgetieben) thou shalt have the fixed gold and silver in the Cupel.
But ’tis to be known, that these Operations may be done without Copper, but yet will yield more ☉ and ☽ if Copper be added; not only for that the ♀ it self gives forth its ☉ and ☽, but because Tin of it self, without the admixtion of ♀, doth not willingly let go its own ☉ and ☽. But in seeking of shelter amongst its own ♀, and withdrawing it self to the Scoria, is there hidden (the Labour being finished) the Scoria can no more attract it into it self.
♀ therefore is as it were a Receptacle, wherein the Sun and Moon collected and separated out of the mass, can defend and hide it self, and is by Chymists called a Bath or Balneum.
In the 4th. Chapter, which treats of ♀, a more large account is given of this labour of metalline Glass. Moreover gold and silver may be separated out of tin in this wise.
Melt common Lead in a Test (treib scherben) under a Muffle (een muffel) and being throughly hot, cast in a little ♃, and it will incontinently have Ingress, but will forthwith ascend and kindle like burning sparks and go into ashes; which must be taken off with a crooked Instrument, and more new Tin put in; which being burnt, let it be taken out. Repeat this labour so long, till all the Lead be devoured as it were by the Tin.
