_Yet another way of extracting the Tincture from Gold._
_Recipe_ of our dried Red Bloud of _Sol_, in the form of Powder
irreducible one ounce, or an ounce an half of our Sulphureous fixed
_Sal-mirabile_ five, six or seven ounces. Both which mixt together
put into a strong Crucible; which covered, set into a Wind-Furnace,
giving Fire so, as they may flow together like Water for the space
of half an hour afterward pour them out into some Iron Vessel, or
Cone, when the _Sal-mirabile_ hath drawn from the Tincture of Gold a
Bloudy Colour. The Mixture cooled, separate the Red _Scorias_ from the
_Regulus_, which will be white as _Lune_. Pulverise the Red _Scoria_,
or tinged _Sal-mirabile_, upon which pour common Water; this Water
dissolves the _Sal-mirabile_, not indeed tinged with a Red, but
greenish Colour. Filter the Solution, and evaporate the unprofitable
Water in a Glass-dish. Then in the bottom will remain a Red Salt, which
fortified with the Seal of _Hermes_ or Luting of _Sapience_, keep for
a sufficient time in a continual Fire of Coals: for then the Sulphur,
as yet immature, will fix it self with the _Sol_, and become constant
in Fire. From that Lute of _Sapience_, you may afterward (by the help
of a proper Magnet) abstract a fixed Tincture, and convert the same to
Medicinal use.
_Note_: That green Saline Water, in which the Redness is latent,
coagulates _Mercury_ into _Sol_, not indeed for wealthy profit, but
onely by the benefit of that to know the possibility of such a Work.
The Red slime, whence the Salt is extracted by the benefit of common
Water, must be taken out of the Filter, mixed with new _Sal-mirabile_,
and in a strong Crucible be made to flow well for half an hour. Then
also more Tincture will be extracted, and a white _Regulus_ of _Sol_
again settle to the bottom. If this labour be a third time repeated,
the Tincture will be good, and a white _Regulus_ will again settle, yet
not so much, as was the first and second time.
