Thanks a lot, m!
The only Antonienhütte pieces I was able to find were the Knizek pieces, no other ranges...
Your
swirled, marbled vase seems a little similar to mine, just the inner casing is opaque white, while the one in mine is transparent yellow. (I did search for "marbled vase" quite a while, but not much on the net)
Edit: searching for "Agate" glass was more successful -- would this be a better term than "marbled"?
This vase has a rather similar pattern (but not attributed to a maker unfortunately)
BTW, I took the vase with me to work today, and tested it under UV -- NO glow, so not Uranium, just greenish-yellow glass.
