Hi. I've attached an image of an 1940's Elis Bergh Kosta dish I found a little while ago that made me think this bowl was perhaps Scandinavian, mainly colour (both are a similar pale amethyst) and vaguely similar in design. However since posting I've been trawling through Scandinavian & Czech glass - again I found a vaguely similar Josef Hospodka dish, but with no colourway to match this one, and also not similar enough. Unless someone comes back with some pointer to a Scandinavian or Czech design I'm now pretty sure it's not from these areas. But during my trawling I came across a couple of references to Japanese art glass so was just about to start going down that route. I know absolutely zilch about Japanese glass, and the references I read seem to be saying that glass from the 1960's / 1970's was basically adaptations of (mainly) European designs but I'm happy to be corrected on this. Onwards to Japan and any pointers would be much appreciated.
