Topic: Grey glass vase with tiny air bubbles flecked with gold...any suggestions?

[ian the sculptor]

This vase looks is well made but no signature and I can't find a similar one. It has the look and style of a piece of Italian glass makers.  The tiny air bubbles are flecked with gold - the large one on base is good example.  Your thoughts would be welcome

I have two pieces which have these these gold filled bubbles with black surrounds.
One is a foot goblet by Bjorn Weckstrom from Nuutajarvi, the other a Unikat bowl from Peill and Putzler. The bowl has kind of cobwebby black strands all around the bubbles.

The bubbles are very distinctive. I do not know how they are produced. The nearest thing iI have seen was on the fairly recent TV series "Make it at Market" where a glassmaker had come up with a technique of putting honey into a mould before dipping the hot glass in.

This is no P&P Schleiergraphit but a more modern version. I have somewhere a similar item and I suspect it is Italian, but could be German (Gralglas Durnau, and Zwiesel jump to mind, but there are others who made similar). It is also no Nuutajärvi, I have that version as a square bowl somewhere (in banana box no. 261A).

The technique is from Daum who made a limited number of pieces in the 1930s; it was also experimented on by Wiedmann (ex WMF) who ended up at P&P after his return and brought the graphite reaction into production..

The closest I could come to it was the Ercole Barovier 'Barbarico' range. It was the only one I found that used the grey glass and the gold inclusions creating the tiny bubbles over the whole piece. But nothing like the shape.

Ivo, the bowl is fully marked P&P Unikat. It is not Schleiergraphit, but it is P&P.
So is this one. It's illustrated in Lesley Jackson as Horst Tusselman, and it is marked. It is not Schleiergraphit either.
Bjorn Weckstrom made his very few foot goblets at the Nuutajarvi works. I suppose they are not actually official output.
I have found an auction of a pair of Weckstrom decanters, which were made at Nuutajarvi and have labels

He made very little glass before specialising and making his name in jewellery.
