And we want to share his observations here: http://www.chladnis-heirs.com/vip/tam1.jpg http://www.chladnis-heirs.com/vip/tam2.jpg It turned out, that all fragments incorporated into that material are really meteoritic fragments! Even the large round fusion-crust-balls or bubbles emerging from the surface had a small fragment left inside. The fragments themselves are modified, the smaller ones seemed to be changed by heat more than the larger ones - but in all the original H5-matrix is still cognizable. No terrestrial stones or fragments he could find. Strange is, that the some of the assembled fragments show a thicker own fusion crust, some a thinner, some no crust at all. The dark "glue" between the fragments revealed under the microscope to be a weird mixture of a black melt (perhaps fusion crust too?), tiny glassy pearls and metal grains, the latter of a sometimes quite large size (possibly troilite). I decided, to name that material from now on to honour the observer: "Ralewite" :-) In the German meteorite forum, we're speculating about the formation of that strange conglomerate. Were from a flying meteorid in stable flight, developing a special fat crust, fragments merging from the apex to the backside, where they assembled? Was a stone with still soft fusion crust crossing a debris cloud of a fragmentation of another stone close in front of it and larded with splinters? Any other ideas? Ahem, of course we were already asked, whether we would sell some of the cuts. Well, perhaps 4 halves or so we can offer. Difficult to set a price, cause it's such an unique phaenomenon. So I'd like to orientate the price, on the result the specimen of glass melt without meteorite fragments, where in this discussion was reffered to, yielded on ebay. Guess that's o.k. cause these are cut and contain meteorite fragments, nobody will say anything against: 60$/g Best!
