Lead from iron.
Lead from copper.
To transmute Copper into Lead, first whiten copper with sublimed Mercury and fixed arsenic until white as Silver, then granulate it. Take equal portions of it and good reducing powder; first cement it, then melt it into a regulus. You will have a true lead regulus.
Copper from lead.
Conversely, transmuting lead into copper is easy and requires no exceptional skill. Layer lead plates with calcined vitriol or crocus of Venus, cement them and finally melt them. You will see any native lead transmuted into good, heavy and ductile copper.
Electrum resembling gold.
If this copper or any other copper is beaten into plates, layered with thuria and calamine, cemented and finally melted, it is transmuted into excellent reddish electrum resembling gold.
To make English tin from lead.
To transmute Lead into Tin, beat Lead into plates, layer it with sal ammoniac, cement it and finally melt it as described above. All its blackness and darkness is thus removed, and in whiteness it becomes like the finest English tin.
Oil of sulphur transmutes gems.
Having heard a brief account of several metallic transmutations, learn now about the transmutations of gems, which are also varied and by no means alike. See how great a transmutation of gems lies hidden in oil of sulphur. Any crystal can be tinged and transmuted in it and, with time, graduated into distinct colours so that it resembles a hyacinth, garnet or ruby.
