The Tincture consists only in the _Spirit of Copper_, and most of all in that of his Bed-fellow; it is a meer Vapour, stinking and ill-sented in its beginning; this Mist must be dissolved in the manner of a Liquor, that the stinking, incombustible Oil may be prepared thereof; but yet it must have and take its beginning out of _Mars_; this Oil unites freely with the Spirit of _Mercury_, assuming all Metallick Bodies speedily unto them, if they be first prepared in all points as I have advised in my Keys. I observe not the Order of the Planets, and not without just grounds; for I observe the order of their Birth, by which I am directed; for because _Venus_ hath much Sulphur, she is sooner digested and ripened together with _Mars_, before other Metals; but because unconstant _Mercury_ shewed them both too little assistance, therefore no room is left him to work harder, by reason of the superfluous Sulphur, so that they could obtain no melioration of their unfixt Bodies. Now I will reveal a Secret unto thee, that Gold, Copper, and Iron have one Sulphur, one Tincture, and one Matter of their Colour; this Matter of the Tincture is a Spirit, a Mist and Fume; as aforesaid, which can penetrate and pass through all Bodies, if you can take it, and acuate it by the Spirit which is in the Salt of _Mars_, and then conjoin the Spirit of _Mercury_ therewith in a just weight, purging them from all impurity, that they be pleasant and well sented, without all Corrosives, you have then such a Medicine, whereunto none in the world may compare, being fermented with the bright shining Sun, you have made an entrance penetrating to work, and to transmute all Metals.
