Simply put this is a really ugly mineral that can even have an unpleasant odor. A natural parrafin waxlike substance derived from Hydrocarbons, this looks much like a rotted banana, it is translucent and has a density less than 1 so it floats. This is an old specimen from Poland with a 1930-40 vintage Schortmann label, this piece is now almost completely odor free perhaps because of its age. However the literature tells us that heating to a moderate warm temperature or any rubbing will again produce the bad smell along with a negative electric charge. The name comes from the Greek meaning "stench wax". This is a super strange mineral that is never seen for sale (and I have never been asked for any either). This locality is not listed in Mindat but that may be due to the many changes to the names and geography of that area over the past hundred years. Certainly not a specimen for a collector of fine esthetics, but a large example of a legitimate mineral almost never seen in any collection. Weird.
