Oil which may be prepared out of that Glass, will be a
very fixt Oil, and will really give an ingress and Medicine of
perfection to the imperfect Metals.

These words and opinion are good and true, but it will not be nor
appear such indeed; for I tell you truly, without concealed speeches,
that if you lose any of the aforesaid _Sulphur_ in the Preparation or
Burning, for a small fire may easily prejudice it, you then have lost
the true penetrating Spirit, which should make the whole Body of
_Antimony_ to a perfect red Oyl, which should also ascend over the helm
with a delightful sent, and curious Colours; observe likewise, that the
whole Body of this Mineral, with all its Members, should be but one Oyl,
and ascend over the helm without any loss of weight, excepting the
_feces_.

How should the Body be brought to an Oil, or yield its pleasant Oil, if
it be brought to the last being of its degree, for Glass is in all
things the utmost and last.

You shall likewise know that you shall not obtain that perfect noble Oil
in the least, if it be extracted with corrected Vinegar poured upon the
_Antimony_, nor yet by Reverberation; and although its various colours
may appear, yet is it not the right way; you may indeed get an Oil, but
you must know that it hath no part of the Tincture, or power of
transmutation in it.

_Now we come to the Manual Operation._

Take in the Name of God, and of the Eternal Trinity, fine and very pure
Mineral _Antimony_, which is fair, white, massie, and inwardly full of
yellow Streaks or Veins, and likewise of red and blew Colours, and
small Veins, this is the best; pound it to fine Powder, dissolve it by
little and little in _Aqua Regis_, that the Water may conquer it. After
Solution take it out immediately that the _Aqua Regis_ may do it no
prejudice; for it will quickly dissolve the Tincture of the _Antimony_;
for our Water in its nature is like to the _Ostrich_, which by his heat
can digest Iron, and consume it to nothing; for the Water will consume
it, and turn it to a Mud, that it shall remain only as a yellow Earth,
and then is it quite spoiled.

Take an Example hereof from Silver, which is dissolved, fair, pure and
fine in these our Waters, but if it stand a night therein while the
Water is strong and full of Spirits, I tell you, your good Silver will
be corroded to nothing in these our Waters; and though you would reduce
it into a Massie Body, you cannot; for it will remain as a pal
