Hi Mac
I would really appreciate it if you could upload your pictures directly to the board please.
Otherwise when they get moved around they are lost for future reference and so the information becomes redundant and not useful for others in the future.
And in answer to your point on the blog, whilst I'm not sure this helps, I do believe there have been id'd Kralik martele posy vases with thorn feet, iridescent and I think at least Christine's was possibly uranium glass. The other looked as though it might have been from the picture and it was debated, however I have one in what looks like it should be uranium glass, and it isn't (so that particular piece may well have turned out not to be but the OP did not come back and confirm on the thread). Mine doesn't feel lightweight and has a cut and polished rim.
Many thanks
