I was intrigued by the colour of this vase since I first saw it a few weeks ago at the fleamarket.
Yesterday it had wandered to a cheaper stall, so I purchased it

Delicate vase, 13.5 cm high, four indentations to the sides, rim fire-polished, neat circular polished pontil mark.
Teal coloured, glossy surface, with a slightly iridescent golden crackle pattern. In some areas there is another layer of cobalt blue glass visible, but not from the inside (see pics).
So 3 or 4 layers in a quite thin-walled piece...
I did search for hours yesterday, but couldn't find much.
First thought as usual was "Bohemian", so I looked through those fabulous websites by Craig and others.
Similar shapes, similar techniques (Lötz "Mimosa", Kralik "Soft Crackle"), but no real match, especially regarding colours or lustre.
Remarkably similar is this red crackle vase by Durand
>> LinkBut I always tend to think that American glass is rather unlikely to be found here in Austria.
And I don't know if the Durand attribution is correct -- other Durand crackle pieces I found on the web looked quite different.
Thanks for any help!
