Very interesting first post. First of all, I looked at the catalogue in question and I'm amazed at your memory. They do look roughly the same shape, although the top of the vase is cut off in the shot of the catalogue I get.
Having said that, my first reaction was Bo Borgstrom for Aseda, although I haven't been able to find an exact match. Is it heavily cased?
I haven't seen any Skrdlovice with inclusions like that. Of course, I'd wait until the sages of Skrdlovice, Jindrich and Robert, check in with their verdict.
I think "schaumglas" is the German term for pulegoso, and as I don't see any bubbles in this piece, just inclusions, I would say no, not Schaumglas.
Nice piece, though.

Added later: The Borgstrom piece that I've found that most resemble this is on p. 54 of Smoke & Ice. It's dark gray, however, and has bubbles.
