Because therefore God himself is a fire, and hath never appeared to his Saints in any other shape but that of fire, and besides also all Salts are generated in the moist bowels of the earth from an Astral fire, and on the contrary, a true fire may by the operation of Art be extracted and rendred palpable and visible out of all Salts, it being that which without doubt lay not hid unto them, therefore it is also very likely that those Philosophers have not without a cause of great moment written that a certain Divine or fiery Being did secretly lurk in Salt.
But that they have intimated not any thing to be better, or more noble than that fiery and saltish Spirit may be foreseen by an easie conjecture; for if a certain divine thing shall lie hid in Salt as they write, it shall of necessity follow that that divine spark being freed from all its earthly bonds should be far superiour to all earthly things in beauty, virtues, efficacy and power; and that next to the eternal God himself it should remain the chiefest and most precious Pearl in the World.
But who shall teach us the manner of separating so precious a Pearl out of the common and Kitchin Salt? none but God alone, or some good friend; who can make his friend a partaker of the knowledge received from God?
But since that very few mortals do seek, love, fear and honour God with sincere hearts, but do much rather cleave fast unto the frail and unjust Mammon, and attribute divine honour unto the same; its no wonder that God doth reserve those things to himself, or at least doth sparingly bestow on us those things which he abundantly supplyed the Ancients withall from his own bountifull hand: And moreover the same omnipotent Creatour enlightning some fit subject, with a certain spark of nature, grants unto him also so much wit that he knows that by a due silence he is to beware of this wicked dreg or dross of the World. Whence it is no wonder that the light of nature is at this day made known to so few mortals.
But before I treat in many particulars of that precious Pearl of Salt, it seems altogether necessary for me, first to shew the manner and reason of extracting that fire out of Kitchin Salt; the separation whereof can be perfected in no other respect than through the violence of common fire, to wit, whenas the Salt being mixt with a certain earthly matter that it cannot flow, is urged in a retort with a most strong fire, that the more pure part of the Salt, which is nothing else but a sharp spirit, may depart into the Receiver joyned to the Retort, in which sharp and sweet spirit a most efficacious fire lurketh which in manner following is to be extracted and concentred.
XII. Of the preparation of the fire of Salt.
Take of this acid or sharp spirit of Salt, rectifie it out of a Glass Retort in sand; the flegm will come over first, which was put in the receiving Vessel in the first Distillation to condense or collect the spirits the more commodiously. After that all the flegm is come off, and acid drops begin to come, remove or change your Receiver, and take your spirits therein; continue the Distillation so long untill all the spirits be come forth, it being indowed with an acid sweetness, is an effecter of very many operations, which doth bring much profit both in Medicine and Alchymy, as is manifest out of diverse of my writings, and especially out of the 2d. part of my Furnaces, and the comfort of Mariners.
In this sweet and sharp spirit like Wine there is an infernal fire hidden, which doth equally like Coals burn up all things put into it, like as the fire of wood and coals doth Vegetables and Animals, and it reduceth all things which common fire doth, by calcining them into ashes, such as are immature metals, tin, lead and the like, which when they are put into it, it burns them up by calcining them into white ashes.
XIII. A Concentrating the rectified Spirit of Salt into a moist and cold Fire.
Every Spirit of Salt consisteth of two things, to wit, Fire and Water, which water the fire doth so firmly co-knit to it self, that it cannot be wholly separated by any distillation or rectifying; but it always adheres to the fire, how often soever it be rectified or distilled: if any one therefore desireth by rectifying to separate them he must of necessity put immature metal-like subjects to the Spirit of Salt, the which, by how much the more immature or unripe they are, by so much they render the spirit of salt the purer; such are Lapis Calaminaris, Zink, and Iron, which by reason of their moist and attracting nature, do draw to them that invisible fire out of the spirit of salt, as it were that agent whereof (as to their maturity or perfection) they are necessarily destitute, and without which fiery agent, a metallick kind of body is able to attain unto no perfection in the earth.
