Now there are other Transmutations of imperfect, and impure Metals, as the transmutation of ♂[Mars] into ♀[Venus], which may bee done divers wayes.
If plates of Iron bee boiled in water of Vitriall, or bee cemented with calcined Vitriall, or being red hot be quenched in oyl of Vitriall.
These three ways Iron may be transmuted into very good, and ponderous Copper, which indeed flows well, and hath its weight as well as any naturall Copper.
The Transmutation of Iron into Lead.
Plates of Iron may bee as it were reduced, and transmuted into Lead, so that it bee as soft as naturall Lead, but doth not flow so easily: and the processe is this:
Take Filings of ♂[Mars], and so much of the powder of Borax, mingle them well together, put them in a crucible, and into a wind furnace, let there bee made a strong Fire, but so that the ♂[Mars] doe not flow, but stand as it were in a Cement for a whole houre, then encrease the Fire, that it may bee red hot, and flow: then let the crucible cool of it selfe, and thou shalt find the regulus of Lead in the bottome of the crucible, soft, and malleable, as naturall Lead can be.
The Transmutation of Copper into Lead.
But to transmute ♀[Venus] into ♄[Saturn] the processe is this:
First of all bring Copper with ☿[Mercury] sublimate, and fixt Arsenick to bee white, yea as white as ☽[Moon], then beat it small. Take this, and the powder of Borax, of each a like quantity, and first cement it, then let it bee melted into a regulus, and thou hast a true regulus of Lead.
