The antimony deposit at Schlaining is a part of the Rechnitzer Schieferinsel. It consits of upper greenschist, phyllite, lower greenschist, lime schist, and Caker conglomerate.
Serpentine is Mg6((OH)8Si4O10), which means it is a variety or at least a close relative of quartz. Its specific weight is 2.6 to 2.7 and its hardness 3-4 (after Mohs). The physical difference of Edelserpentin is its much lower hardess, which is only 2 to 2.5. And of coourse its fine colour.
The Bernsteiner Felsenmuseum (Rock Museum of Bernstein) is a museum and show mine. Bernstein means amber, but neither the museum nor the mine have to do with this biogene semi precious gem, it is just the name of the town. The museum is the work of the artist Otto Potsch, who creates artwork from a rock called Edelserpentin (literally fine serpentine). As there is only one single deposit of this rare semi precious gem known today, which is here at Bernstein, there is only a German name for this fine rock. The green and blueish rock is similar to Chinese jade, but has a different chemistry, it is a variety of ophite or serpentine. Here at the museum is a shop where the extraordinary artworks of Otto Potsch are sold.
The mine is originally a copper and iron mine, where chalkopyrite and pyrite were mined since the Middle Ages. It is located right below the museum and shows typical mining technologies and heavy machinery. Beneath the historic copper mining there was an important antimony mining at Schlaining, some kilometers to the south. Today only the gemstone mining remains. About 2000 tons of serpentine are mined for a single ton of Edelserpentin. Only the best quality rocks are used for the artworks. The rocks of lower quality are used as tiles for floor and walls, and the poorest quality is used in road construction, as it is very hard.
The museum cantains numerous fine minerals, ores, and fossils. One of the highlights is an axtraordinary rock crystal cleft, which was found at the Hoher Sonnblick. A part of the exhibition is dedicated to Adolf Höfer, an ancestor of Otto Potsch, who was the first to work with the Edelserpentin. His complete workshop, with the wooden machinery, is on diplay.
