and "conjunctive solvent"; and with this alone, and gold, or silver?
physically dissolved in it without the help of another,
the best medicine is made and perfected, which composition never
varies, which should be well noted; for transmuting
imperfect metals, or mercury, into the best
gold or silver, according as it has been prepared with the Sun Gold or Moon Silver.
The second is indeed drawn from alums and mineral salts, but this is worth nothing without the
help of the vegetable spirit.

Calxes of metals

These are made by calcining them with Sulfur
or with strong waters acids, then washing them with pure water
and drying them.

Salts of metals

These are made if the bodies are reduced to ashes
through calcination, from which a lye is prepared by pouring a proportionate water or a suitable solvent
upon them, which, having been strained or decanted,
is evaporated by a third part and exposed to the cold, so that from there
it may grow together into a consistency. This is called the Salt of metals.

Sublimated metallic Sulfur;

likewise it is called the element
of earth dissolved through calcination and dried.

Tinctures and essences

so-called, are made from calcined metals
through extraction with a proportionate solvent,
digesting them together at a light heat, and decanting the solvent
enriched with the tincture, and thus repeating until
the solvent is no longer colored.

the ordinary exhalations? of metals are acquired. They do this by calcining
them, and by making an extraction with a proportionate solvent or a suitable lye,
and afterward drying it.

Mercuries from metals

These are made by the addition of salts
and resuscitated solvents, and through putrefaction,
sublimation, and revivification.

Metals are reduced into flowers.

such as Lead, Tin,
Antimony, Sulfur, and similar things; if they are sublimated, and
flowers of perfect metals can be made, as for example:
Dissolve the best silver in aqua forti strong water or nitric acid, and from it
draw off the strong water as many times as necessary until it remains like
melted honey, and sublimate it, thus you will have flowers of silver;
wash those and dry them: those flowers can indeed be vivified into
running Mercury by grinding them together with vinegar, or with
salt of tartar.

Saffrons original: "Crochi" of metals

These are made by calcining them with strong
waters or with sulfur.

Oils from metals

These are made if they digest their calxes with saline spirits, that is,
with spirits of wine or urine fortified with their own salts,
and distill them together.

Metals are reduced into Vitriols.

if filings are calcined
with sulfur and afterward smoothed, as will be said more clearly
elsewhere.
