Hi - yes, I think the word bowl is adequate, and guess you have found only two mould seams on this bowl. Some of the pre WW II Brockwitz bowl designs were very ornate, with complex looking handles which had the appearance of have been applied separately after the bowl had been made, though I think those moulds did incorporate the handles, rather than the handles being applied separately, afterwards. I'm slightly confused as to the appearance of clear glass on parts of your handles - perhaps you can explain to us why the top parts should appear clear - is it, for example, simply that the glass is thin in those areas?
There may be some people who might suggest this design isn't art deco, so would you like to tell us what are the features of your bowl that convince you to think deco?
You may have already looked at the pressglas-pavillon.de curated by Pamela Wessendorf - I don't see your bowl there - in either the attributed or unknown sections .............. but if you've not previously seen this amazing resource do have a look. Unfortunately, the world is awash with bowls, and yours may remain unknown, unfortunately.
