Wee see that part of the lead, from thence goes away in smoak as in the fire, whence Soot is procreated, a part thereof is burned, namely its sulphurous part, and part grows tough within the _coupelles_ almost in the manner of Glasse or varnish. Of the two first volatils, there is no account to be made thereof, for they goe and disperse themselves. But bray the _Coupelles_ where this vitrification is as it were baked, wash them well with warm water, to depure them from their grosnesse and uncleannesse, then put them into a descensory with a strong expression of a bellows fire with the Salt of _Tartar_ and _Salnitre_, and there will fall down through a _Metalline_: which being _recoupled_ with new lead you will find more fine, without comparison then at first, and ever from that time forward, more and more, by reiteration as abovesaid. So that hee, that would take the patience to boil the lead on a regulated and continuall fire, that should not exceed its fusion, that is to say, that the lead should therein remain alwayes melted and no more, putting thereto a small portion of quicksilver or sublimate to keepe it from Calcination, and to reduce it to powder: at the end of a certain time, you shall find that _Lamwell_ hath not spoken frivolously to say that the six grain is contained in power with lead, (that is to say) gold and silver, would multiply and increase themselves as the fruit upon a tree doth. [Sidenote: _Coups a ruer._ pag. 87.] But to return to these oils of long durance, whereof he might make a large volume that would run through not all but a part: Let him draw from the Tartar of wine, of which the best comes from _Mompellier_, even that which adheres unto the Tun. One which is very important, Tartar is one of the subjects, where those who practise in the fire, do find so _many blows to cast_. Take of this Tartar beaten into small powder and put it in a leaded earthen pot with clear fountain water, upon a Trevet or furnace, making it boil easily and scum the villainies and filthinesse off with a feather: the silver _Crusts_ that shall afterwards arise, gather them with a head of Glasse, where these grosse _moules destang_, of _mudd_, so long till they rise no more, renewing the water by measure when it comes to diminish. Turn it by Inclination, and put a part, that which rests in the bottom in the shape of Sand. Put again the Crusts in new water, make them boil gently as before, and gather together the Crusts that shall rise up more clear and lucent then the first, separating their dregs and impurities, if there be any presented, and reiterate this six or seven times, till your Crusts be clear and shining as silver or pearls. Dry them in the Sun, or before the fire upon a linnen, and put them in a cornue with an open breech, and a graduate fire reinforcing it by smalls: and through the beak of the Cornue, there will issue as a smal rivolet of milk, that will resolve into oil with the Recipient. Passe it once again, or twice upon
