Raden, I'm sorry, but I know absolutely nothing about meteorites. The meteoritic material I used came from a very big, well known American meteorite---Arizona or Colorado or somewhere like that. It was a lot of very small pieces, and it was very, very expensive, I think much more expensive than this stuff is now, as with meteoritic material , the market seems to have opened up.
My understanding of the current situation is that there is presently no problem at all in getting whatever one may need in the way of meteoritic material.
Once the inside of the meteorite is revealed it is easy to see if it is stone or metal, but looking at the outside I wouldn't have the vaguest idea of how to differentiate.
I did remark previously that it would be quite improbable that any Javanese maker could weld pure meteorite. I've thought about what I said there, and I'm probably wrong. If a large enough piece of material were to be supplied , and the maker understood that he needed to work very softly in the initial stages, it could probably be brought together into a useable ingot of pure material.
