What Coagulation is, and its kinds.
Coagulation is the sixt degree: Now there is a twofold Coagulation, the one by Cold, the other by Heat, i.e. one of the Aire, the other of the Fire: and each of these again is twofold, so that there are foure sorts of Coagulations, two of Cold, and two of Fire.
The Coagulations of Fire are fixed, the other of Cold are not.
The one is done only by common Aire, or without Fire. The other by the superiour Firmament of Winter starres, all which coagulate Waters into snow, and ice.
But the Coagulation of Fire, which alone is here to bee taken notice of, is made by an Artificiall, and Graduall Fire of the Alchymists, and it is fixed, and permanent. For whatsoever such a Fire doth coagulate, the same abides so.
The other Coagulation is done by the Ætnean, and Minerall Fire in Mountains, which indeed the Archeius of the Earth governs, and graduates not unlike to the Alchymists, and whatsoever is coagulated by such a Fire, is also fixed, and constant; as you see in Mineralls, and Metalls, which indeed at the beginning are a mucilaginous matter, and are coagulated into Metalls, Stones, Flints, Salts, and other bodies, by the Ætnean fire in Mountaines, through the Archeius of Earth, and operator of Nature.
What things cannot be Coagulated.
Also wee must know that Fire can coagulate no water, or moisture, but only the Liquors and Juices of all Naturall things.
Besides also there can no flegm bee coagulated, unlesse in the beginning it was a corporeall matter, into which by the industry of a skilfull Alchymist it may return.
