IX. Of the general use of this Oyl in Alchymy.
By this mineral fire, all kind of Transmutations of things are perfected, but particularly it exalteth some of the more base metals into a higher degree, and makes them more constant, of which more shall be said in the following Chapters or Treatises.
In the general, some Vegetables, Animal and Mineral subjects, may by the operation of this Oyl be reduced into fixt Medicines, and indeed far more commodiously than by the common fire of Wood or Coals. And moreover which is a far greater thing in this very oyl a fiery Tincture is hidden, and is manifested by the benefit of Art, as Fryer Basilius, and other Philosophers do affirm.
X. Of the use of this fire in other Arts.
By the virtues of this invisible, and yet essential fire, all sorts of most profitable matters are performed, the which notwithstanding is not here safe for me to describe, but I am constrained to refer it till another time, it onely in this place seems worthy my labour, briefly to shew that this fire performs all those things which the fire of Coals is otherwise wont to effect.
Truly it is a fire, but it shineth not like the fire of Wood or Coals: But he that will have it to shine, he must needs add unto it a subtile or fine Sulphur, that he may extract or allure forth of it a visible fire.
This fire being defended against the entrance of the Air, remains occult for many thousands of years, and doth not manifest it self, unless any one make it manifest.
Truly it is an admirable fire, and most fit for the effecting of many incredible things, whereof we have spoken many things sufficient for this time.
XI. An evident demonstration of such a fire lying hid even in the Salt of the Kitchin, and that known to every one.
After that Plato and many other Philosophers took notice that nothing endowed with life did consist without Salt, and that dead Carcasses themselves were preserved for a long time from putrefaction by the virtues of the same; they thought and wrote that a certain divine thing lay hid in it. But after what sort this divine and hidden thing is to be made visible, they have not taught. But without doubt, those most wise Philosophers would by this word shew and denote something of a singular excellency.
