Topic: Large colourful vase, 'green aventurine' or mica, Vasart? Or Czech?

[glassobsessed]

Vasart is my best guess at the moment for this vase, confirmation or suggestions for other makers would be very welcome.

It is substantial weighing in at over 1.5kg, 9 inches or 23 cm tall. File polished rim, ground but unpolished pontil mark. Colours include yellow, red, blue, white, purple and a sparkly green which I suspect contains mica but is hard to capture on camera.

Not Vasart glass, sorry cannot be of any more help.

Very very nice -- whoever by it is.

Not Vasart, no. I don't think any other Ysart either.
What a strange and unusual thing!
I'll put a thinking cap on, and some feelers out.

Is the green aventurine only under bits of green glass, or do you think it is truly green aventurine?

Gro Bergslein used green aventurine in very colourful splodgy bits, but the colours I've seen her use are quite different.
It's uncommon stuff.

Thanks all.

Okay, not Vasart then.

The sparkly bits are only in the green, just checked with a jewellers loupe, they are very small sparkly bits, considerably smaller than the air bubbles. Not sure they are mica or aventurine...

Sue, your suggestion of Muller Freres is interesting, they did make vases with a similar shape and complex mottled colours. No acid etched makers mark on this vase though sadly.

WMF? Schneider? The colours look familiar

By the look of it this is not green aventurine, but green powdered, then partially coated in aluminium nitrate, then clear cased and finished. This would explain why only the lower part has these tiny air bubbles which produce the sparkle effrect. WMF has indeed used this method - but usually in combination with silver nitrate which I cannot see.  It would also be strange to have a fire polished rim on a thick walled vase - are you sure it is not tooled?

It was my brother suggested Muller Freres; like Christine, my guts thought Schneider. My family seems to suspect French.  I liked the Muller Freres suggestion, the piece "fits" with a lot of Muller Freres I've seen - big, colourful and chunky (with fire polished rim!).
Daum?

Maybe a long shot, but your fabulous vase reminds me a little of my 1930s lamp base (which is most likely Czechoslovakian, perhaps S. Reich / Krasno).
It has the same very fine glitter only in the green areas.

More of these Ikora style (yet rather surely not WMF Ikora) lamps in that thread...

I really appreciate the suggestions and possibilities, thanks all.

I am not sure how to tell the difference Ivo, the profile of the rim is not symmetrical, there is a much shorter and steeper curve on the inside while the curve on the outside is much shallower.

Back to the 'aventurine', using the loupe now with daylight I am pretty sure I am looking at small flakes of mica, they are irregularly shaped (some triangular some more squared off) and definitely flat, when tipping the vase they illuminate and catch the light before 'winking out' again.
