This is the variety of Hydromagnesite, idogiobertite, a hydrous carbonate of magnesia. The vial is an antique specimen labeled 1906 and filled with the powder of this mineral. An early reference to this variety can be found in J. Logan Lobley's "Mount Vesuvius". Here Lobley describes the mineral as rare and found enclosed in a large fragment of ancient lava...."Eugenio Scacchi gives it the name Idrogiobertite" (from Vesuvius). Dana (6th Ed) states this variety was named by Scacchi on Dec. 12, 1885. Very few specimes out there would have this varietal name placed upon the specimen. Rather most will call it the proper defined name as "Hydrmagnesite".
