NB. The Mercury of Luna cemented with ( A ) may be likewise reduced by this means, (viz. with this flux) that we take one part of Flints that will melt in the fire, and of the fixt salt of ashes four or five parts, and so mix them together, and melt them into a white glass; ’tis able to reduce the best Cements. And this is the best way of all of reduction.
Besides, all those ways of reducing a Cement, there may even this way too be instituted, and that not unprofitably. Take of the fusile Glass of Lead four parts, of the cementing Powder one part; melt them in an iron Crucible in a strong Fire, and some of the Lead will be reduced out of the Glass of Lead, and will be near (or partake of) ☽: This Lead is to be blown off on the Test, and you shall find an aureous ☽: But for as much as the Lead separated from the Glass of Lead in the iron Crucible, contracts a blackish colour from the Iron; it is profitable to add to the matter in the filling or melting, some Salt of Ashes, as being that by which the Lead becomes depurated, and so is easily separated on the Test.
But if so be, that (for this work) the Metals (of Minerals) of ☉ & ☽ cannot be had to precipitate the Mercury of ☽ out of them, (then) the artificially-made (vessels or plate) whether simply Silver, or else guilt with ☉, may be made use of; let these be dissolved with the Aq. For. left after the precipitation, & precipitated with Salt water or Aqua Regia, and be edulcorated and mixt with ( A ) and be fixt in a Retort. Now this Operation is to be done in a Retort, that so the precipitated ☽ that is altogether volatile, may not be wasted, which in a Crucible evaporates away, a good part of it, which cannot be so done in a Retort; for in a Retort, that which flies up, sticks in the Neck, and may be separated thencefrom, and be mixt with other Cements: And besides too, the Cement is easilyer separated from the Glass, than from an uneven Crucible; for some part always sticks thereon, and cannot be gotten off.
When you are minded to purifie this Cement sooner (or more speedily) it may be molten with an equal weight of Antimony, and there will arise from your golden ☽ a Regulus, which must be purified with Salt-petre. Concerning which work of Reduction, and which is far easier than that which is done by the help of the Glass of Lead, I have most clearly and fully handled it, in my Testimony of the Truth, or the Explication of my Miraculum Mundi. By this means every ☿ of ☽ may be rendred aureous, and that as oft as one will, yea, even until all the ☽ be changed into Gold by Cementation and Gradation. Now if you would otherwise separate ought of the aureous or golden ☽, or extract the Metals (where nevertheless you would reduce the separated ☉ and ☽) it may be effected by this means most commodiously and most gainfully of all, because the Calx of ☽ is made aureous by Cementation. This labour yields a continual augmentation of ☉, by which we may live very well and plentifully.
Another Augment or Encrease of Sol.
Dissolve ☽ or ♄ in Aqua Fortis, also ♃ in Aqua Regia: (NB. Let there be always thrice as much Silver as Tin;) mix the solutions very accurately, and when you see that all the matter is fallen down (or precipitated) to the bottom; pour off the water, which said water will very commodiously serve instead of Aqua Regia, to dissolve other ♃ in. NB. If your Aqua Regia be not strong enough, it will not at all dissolve the Tin, therefore in such a Case, you may pour on the Tin, Aqua Fortis mixt with simple water, which after they have a while acted upon each other, there must be some salt-water poured thereupon, that so the ☽ or ♄ may be precipitated to the bottom of the Vessel, in which (Vessel) the white ashes of the Tin ly. This matter lying in the bottom, is to be edulcorated, dryed, and reduced by a strong fire, by which operation you have not only an augmentation of your Luna, but it is likewise made golden.
NB. This business may also be thus managed, First, dissolve ♄ or ☽ in Aqua Fortis; to the solution add an equal quantity of Rain-water, pour this mixture upon ♃, and let the solution be made in a pretty warm place with sand; separate that which is dissolved, the matter that is yet somewhat harder, by decanting or pouring it off; then make the precipitation with salt-water, edulcorate it, dry it, and melt it, and you shall have Encrease.
But if this Mass will not so easily melt, then powder it, and mix it either with Antimony, Glass of Lead, or with a fluxing matter made of salt of ashes and flints, that thereby it may be made fluxile or meltable: That which is made fusile by the help of the Glass of Flints, is presently pure; so is not that which is done by the help of the Glass of Lead, for that must be hence separated, and be (by the benefit of ♁ and ♂) reduced into Reguluses, and be purified and washed by Salt-petre. Therefore it is the better way to promote the melting, with the Glass of Flints than with Antimony, because the ☽ may be afterwards separated without Loss, which is not so easie a thing for every one to do (otherwise.)
The Reduction which is made by the help of the Glass of Lead, is indeed (otherwise) a most easy way, but by that way which is done with Antimony, we get more ☉ than by any other way.
