6. To make melted Tin hard, that it shall shine and sound like [Silver]; Ten R. Dollers.
7. To make white Vitrifications upon Vessels; for Ten R. Dollers.
8. Plenty of Spirit of Salt.
This is not prepar’d after Glauber’s way, and though Glauber was so great a Lyer as to affirm, that in a clear Fire fifty pound of this Spirit might be prepared in one day, yet he cannot produce above one or two pound: Wherefore my invention is much better, and my Spirit is pure, but Glauber’s has Vitriol mix’d in it.
And though I gave Glauber a great Sum of Money to communicate these Secrets to me, yet I have not found any of them true, according to his Information, but was fain, with great industry to seek other waies of working those abovenamed.
And for those that follow, though they may seem to be derived to me from Glauber, yet they have not succeeded by his Information, but I was forced to go another way to work, which will hardly be found by Glauber.
9. To prepare good store of the Spirits of Vitriol, Nitre, Salt, Aqua fortis, Aqua Regis, also Sulphur, after a manner not yet known, and which will scarce be known to Glauber; forty R. Dollers.
10. To produce plenty of volatile Mineral Spirits, which Spirits ascend the Still before the Phlegm; but the abovenamed after the Phlegm.
NB. These Spirits have the same taste that Spirit of Wine hath, and evaporate like it, and are void of corroding: neither do I doubt, but I can produce such Spirits from Metals also, though in metallicks I have made no trial yet.
11. Flowers of Minerals and Metals, almost without diminution, compendiously under a refrigeratory cover, which Glauber never saw; Ten R. Dollers.
