oh ok I see
sorry Michael, I didn't scroll down the link and had forgotten about the blue ashtray. I can see I commented on that thread
but I'd forgotten about it.
Dirk had a conversation here http://www.glassmessages.com/index.php/topic,46485.msg264702.html#msg264702
on that thread that confirmed them as Wiedmann
The reason I had asked about it was because they reminded me of a decor on a piece I had that was by Cari Zalloni for WMF iirc. I will try and find a picture of it if I still have one. It was a bright blue candleholder with just the silver chlorides, nowhere near as pretty as these pieces and no other nice special effects like your vase or the ball candles or the ashtray though. It was just the blue and chlorides that reminded me of it I think. And probably not linked to these pieces at all which is perhaps why I didn't mention it on that thread.
I'll add a pic once I find one.
I didn't spot the vase but I guess a similar shape to the metal one...mmm, it's slightly different to yours isn't it? the flared rim is different.
