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. [Sidenote: 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. [Sidenote: To make English Tin out of Lead.] If thou wilt turne ♄ into ♃ make plates of ♄, 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. [Sidenote: 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. [Sidenote: To Transmute the Loadstone into great strength.] Know also that the Loadstone may be transmuted into a tenfold greater power, and vertue, and it is done thus: Take the Loadstone, and heat it very hot in coales, but so that it bee not fired, which presently quench in the Oyle of _Crocus Martis_, made of the best Carinthian Steel, that it may imbibe as much as it can. Thou shalt by this meanes make the Loadstone so powerfull, that thou maist pull out Nailes out of a wall with it, and doe such like wonderfull things with it, that the common Loadstone can never doe. Moreover, in Transmutation of Gemmes you must know that the world is placed in two degrees of Tincture, and Coagulation. [Sidenote: To transmute the white of an Egge into Amber of any Colour.] For as the white of an Egge may bee tinged with Saffron, and then bee coagulated into a faire yellow Amber: with the smoke of a Pine-tree into blacke Amber: with Verdegrease into green, like _Lapis Armenius_: with green juice into Amber, like the Emerald: and with the Azure stone, into blew Amber, like a Saphir: with the Wood called red Wood, into red, like a Granat, or Rubie: with a purple colour, like to an Amethyst: with Ceruse, like to Alabaster. So all Liquors, especially Metalls, and Mineralls, may bee tinged with fixed colours, and afterwards bee coagulated, and transmuted into Gemmes. [Sidenote: How counterfeit Pearls are made.] So also may Pearles be made like true Pearles in form, so that for splendor, and beauty they can hardly bee discerned from the true: And they are made thus:
