Note, that every one of these must bee beaten small, and bruised before they bee put into the Still.
And thus much bee spoken concerning the Distillation of Waters out of the Vegetable substances.
As concerning the Seperation and Distillation of Oyls, the processe is the same as that of Water, only some of them are to bee distilled per descensum, and cannot ascend as Waters, the processe of these in this case is to bee changed.
But Liquors are not separated in Distillation as Waters, or Oyles, but are expressed from their corporeall substances with a presse.
And here wee must know, that there are some Oyles that are pressed out, and separated after the same manner, by a Presse as liquors are, and that for this reason, because they should not contract an ill odour from the Fire, as otherwise they would doe.
Of this Order is the Oyle of Almonds, Nuts, hard egges, and the like.
Also wee must note, that all Oyles, if they be prepared, and coagulated according to the Spagiricall Art, yeeld a kind of Vernish, Gumme, Amber, or Resine, which may bee also called Sulphur, and that which remaines in the bottome of the Still may bee calcined, and brought to ashes, and from it may bee with warme water alone, the Alcali extracted, and separated from it.
The Ashes which is left behind is called the Dead Earth, out of which never any else can bee extracted.
