EXPERIMENT I. To dissolve crude Gold with dry Bodies.
Tho' Chymists so much boast of their Au∣rum Potabile,* 1.1 as to think it a curious prepara∣tion, yet it is possible to make one without the help of a furnace, or so much time, after the following manner. Having ground four Parts of pure Nitre with two of Rock-Allom, and one of Sal-Armoniack, I put the Mixture into a new Crucible, keeping it in a moderate Heat, till the Mixture contained in it was dry, which being taken out, and presently pulverised, it afforded a Golden Tincture in highly recti∣fyed Spirit of Wine.
