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 pale yellow Earth, and sometimes it will run together in the form of Horn, or of a white Horse Hoof, which you can by no Art reduce into a Body. Wherefore you must remember to take the _Antimony_ out presently after the Solution, precipitate and adulterate it according to the custom of _Alchymists_, that it may not be corroded with its perfect Oil by the Water, and burnt up to nothing. _The Water wherein we dissolve is thus made._ R. _Vitriol_, a pound and a half, _Salt-Armoniac_ one pound, _Azinat_ one pound, _Salt-nitre_ a pound and a half, _Salt-gemme_ one pound, _Allom_ half a pound; these are the Ingredients which belong unto the making of the Water for the Solution of _Antimony_. Take and mix them well together; at first distil very slowly, for the Spirits ascend with greater violence than those of any other common _Aqua fortis_; beware of its Spirits; for their Fumes are very subtile and hurtful in their penetration.
