The mineralogical museum of the Collegio Nazareno of the Piarists Order in Rome was founded by Gian Vincenzo Petrini c. 1760. It hosted minerals and rocks the Popes had received as gifts and given to Piarists to support their teaching, as well as minerals collected from Roman and Neapolitan volcanoes. On March 24, 1769, the museum was visited by Emperor Joseph II, officially there as an incognito tourist but, in fact, to organize the election of a Pope who would abolish the Jesuit Order. On June 14, 1785 the Emperor, by now King of Hungary as well, presented eight crates of minerals from mining areas in Transylvania and Upper Hungary, i.e. Slovakia. This collection had been organized by “Baron of Born”, who also wrote down descriptions of all the specimens (mostly ores), as referred to in Petrini (1791–92). The museum of the Collegio Nazareno has survived and the royal gift is partially preserved, curated by the Gruppo Mineralogico Romano (GMR), a private association of amateurs founded in 1982. The museum now exhibits a rare collection of minerals from 18th century central Europe, organized according to systematics that just preceeded the major scientific changes brought about in mineralogy by the crystallographic approach.

Obsidian samples from different localities of various geologic settings (Armenia, Hungary, Iceland, Mexico, Slovakia and Turkey) were analyzed by particle induced gamma-ray emission (PIGE) technique and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Samples from Mexico and Iceland show higher alkali and REE content as well as higher Nb and Ta abundances than the other samples. Discrimination diagrams show samples from Mexico and Iceland to belong to WPG. The position of the samples from the Tokaj Mts is also definite, and it corresponds to the expectation (VAG or VAG+syn-COLG fields). Using a Li-B diagram the obsidian samples can be distinguished according to their geographic distribution. By means of a Ce-Ti diagram, obsidian from the Tokaj Mts can be divided into three groups that may correspond to the archeometrical C2E, C2T and C1 groups. Phenocrysts in the obsidian samples from the Tokaj Mts, and the Aragats Mts (Armenia) were detected and analyzed by micro-PIXE (proton induced X-ray emission) method. In this way silicate minerals (zircon, pyroxene, biotite, plagioclase feldspars), ore minerals (chalcopyrite, pyrrhotite, pyrite), and other non-silicate mineral (anhydrite) were identified.
