The Third Part of the Prosperity of Germany

Part Three.

it dissolves. While these things are kept thus in the first capsule, the materials of the second capsule, placed one upon the other, heat up, and the useless phlegm evaporates. As long as this capsule also emits smoke from itself, the lye from the first capsule must not be poured into it, but everything must be left to be consumed in itself. Truly, when you perceive that they are cooling, then the lye must be drawn off from the materials of the first capsule and poured onto those which are in the second capsule, so that in this way the contents of the first capsule may again heat up, be consumed, and be changed into liquid. The more often and longer this repeated pouring of the lye is performed, the more and faster the materials are consumed, and from these consumed materials a most excellent Salpetræ saltpeter can afterwards be made, for heat causes the species to rot. Finally, so that you may arrive at the test, take a little of this lye, and bring it to the quantity required for crystallization formation of crystals, then place it in a colder location for crystallization. Dry the salt that you find, and place some of the dried salt onto a hot coal original: "pruna". If you observe it to flare up, it provides you with an indication that it is the time to draw off and collect all of the lye, so that from it, through evaporation and proper coagulation, Salpetræ saltpeter may be made. If, however, the opposite occurs, and no ignition of the salt is noted, the lye must be animated and ignited for a longer time in the hot capsules by the air, which is magnetically attracted due to the heat. With this work rightly established,
