8°: [8], 152 p., engraved frontispiece (showing mining operations).

Very rare. Unrecorded in many of the standard references, this anonymous collection contains much information on chemistry, metallurgy and mineralogy. It consists of 155 experiments and their results that would be especially useful for mining officials investigating various stones and earths. In the preface the author refers to two books published in 1718 and 1721, Geheimer Natur erörffnete Pforten and Der sechs Tagewerk dieser Welt geheime Bedeutung.
