Point VIII
Every common Silver may in the space of a few hours be exalted into the nature of Gold.
This Gradation of Silver is performed by the help of a certain Mineral Sulphur, to wit, of ♂ and Antimony, in this manner. Adjoin to ☽ as much Regulus Martis, and again let it be separated from it by Nitre, which labour is performed in the space of an hour, to the remaining Silver adjoin again as much Regulus, which is again to be abstracted; and let this labour be reiterated five, six, eight, or ten times, which may be done in one day, afterwards let the ☽ be dissolved in Aqua-fortis, then the Gold, which the Nitre by the help of the ☽ hath obtained from the Regulus, will remain in the bottom, which is to be edulcorated, and corporify’d with Borax, the Gold will be good in an excellent degree, but the value thereof is scarce enough to pay for the Regulus, and Nitre. But he that knoweth how to make his own Nitre, or can obtain it without price, may reap a considerable profit: Especially if he know how to transferr the detracted Scoria into further use, which is not here sought, but is only proved that ☽ may be exalted into ☉ by the help of Regulus Antimonij Martialis.
