Part Three.

little cloth together, binds it tight, and weights it down; then the weight presses out the remaining 🜄 water/solvent completely, and the Calces calcined/powdered residues of ☉ Gold and ☽ Silver become thick, like a coagulum congealed mass or fresh cow-cheese when the whey has been pressed from it. But because the Calces of ☉ and ☽ have not been sweetened, the pressed-out silver-cheese is still corrosive and does not want to dry easily. To remedy this, one should put such ☉ and ☽ cheese into a bowl and mix a fourth part as much Salis fixi fixed salt underneath it; thus the corrosive Spiritus spirits are killed thereby, and afterward the cheese can be dried, cemented, fixed, and reduced. When it has then been reduced and one wants the ☉ from the ☽, one must granulate the golden silver mass, dissolve it with fresh 🜄, and precipitate it from other 🜄 with which ☉ has been drawn from the ores, press out the cheese, salt it, and melt it, and afterward granulate, dissolve, and fish for ☉ with it again, as often and as many times as one has ore to extract. Thus, this work can be carried on continuously and good profit can be had from it daily. For the used strong water is good again for extraction after the work is done, but the weak can be prepared into saltpeter, from which good aqua regia is to be distilled anew by adding vitriol. The vessels in which the precipitation of the metals happens, as well as the cheese presses, should be made of strong glass or well-glazed earthenware.
