Now on the contrary, it is easy to transmute Lead into Copper, neither doth it require much pains, and it is done thus:
Take plates of Lead, strow them over with calcined Vitriall, or Crocus of Venus, cement them, and then melt them, and thou shalt see naturall Lead, transmuted into good, ponderous, and malleable Copper.
A Metalline mixture like Gold.
Now if this Copper, or any other Copper be beaten into plates, and strowed over with Tutia, or Capri Celaminaris, and be cemented, and lastly melted, it will bee transmuted into an excellent reddish Electrum like to Gold.
To make English Tin out of Lead.
If thou wilt turne ♄[Saturn] into ♃[Jupiter] make plates of ♄[Saturn], strow them with Salt Armoniack, cement, and melt them, as abovesaid, so will all the blacknesse, and darknesse bee taken away from the Lead, and it will be in whitenesse like fair English Tin.
Now as you have in briefe heard of some Mutations of Metalls, so also know, that there are Transmutations of Gemmes, which indeed are various, and in no wise like.
Oyl of Sulphur transmutes Gemmes.
For you see how great Transmutations of Gemmes there lies in oyle of Sulphur. For any Crystall may bee tinged, and Transmuted in it, and in time bee exalted with divers colours, as to bee made like to the Hyacinth, Granat, or Rubie.
