Nor is it only the fixedst of Metals, but the most fugitive, that I may employ in favour of our Proposition: for Quicksilver will with divers Metals compose an Amalgam, with divers Menstruums it seems to be turn’d into a Liquor, with Aqua fortis will be brought into either a red or white Powder or precipitate, with Oyl of Vitriol into a pale Yellow one, with Sulphur it will compose a blood-red and volatile Cinaber, with some Saline Bodies it will ascend in form of a Salt which will be dissoluble in water; with Regulus of Antimony and Silver I have seen it sublim’d into a kinde of Crystals, with another Mixture I reduc’d it into a malleable Body, into a hard and brittle Substance by another: And
