After this manner also may other metalls, not only Gold, and Silver, but Copper, Iron, Tin, Lead, &c. as also whatsoever are prepared out of them, as red Electrum, the white Magnesia, Aurichalcum, calcined Lead, Laton, Brasse of Cauldrons, and whatsoever metalls of this kind are transmuted, bee with Quicksilver, but first being powdered, abstracted, and separated from what is heterogeneous. For the nature, and condition of Quicksilver is this, that it wil bee united, and amalgamed with metalls, but yet with one sooner then with another, according as the metall is of greater or lesse affinity to it. In this consideration fine Gold is the chiefest, then fine Silver, then Lead, then Tinne, then Copper, and lastly Iron. So amongst transmuted metalls, the first is part with part, then Ash coloured Lead, then Laton, then Brasse of Caldrons, then red, and the newest white. Although for the first course Mercury may take no more then one metall, with which it is amalgamated: yet that Amalgama is to be strained hard through Leather, or Cotton cloath. For by this means nothing but the Quicksilver will passe through the Leather, or Cloath: and that metall which it did attract remains in the leather, or cloth like Calx, which afterwards thou maist with salt Alcali, or some other salt reduce into a metalline body by melting. Now by this Art Quicksilver is much sooner separated from all manner of metalls, then by Distillation, &c. By this processe with Mercury all metalls may after calcination, and powdering be by a skilfull, and industrious Alchymist extracted, and separated one from the other. In the same manner, and that easily, may Tinne, and Lead bee separated from Copper, or Copper vessels, from Iron, and Steel overlaid with Tin without any fire, or water, by the Amalgama of Quicksilver alone. Also Beaten Gold, or Leafe Gold, or Silver, as also any other metall beaten, or ground, being written, or laid over with a pencill, or quill upon cloth, parchment, paper, leather, wood, stones, or any thing else, may bee resolved by Quicksilver, and so, that the Quicksilver may bee afterward separated again from those metalls. [Sidenote: By Corrosive waters.] Now the separation of metalls in _Aqua fortis_, _Aqua Regis_, and like corrosive waters, is after this manner.
