Note 25 — BOOK X.
Herbert Hoover translation
Sal artificiosus. The compound given under this name is of quite different ingredients from the stock fluxes given in Book VII under the same term. The method of preparation, no doubt, dehydrated this one; it would, however, be quite effective for its purpose of sulphurizing the copper. There is a compound given in the Probierbüchlein identical with this, and it was probably Agricola's source of information.
