thanks jp - and I've now been all over this with a magnifying glass but have to say no sign of the word Eda. However, think I'm coming to the conclusion that this bowl may well not be W/Fs. - too many small bubbles, several whitish seeds and what appears to be unmixed colour swirls. The grinding/removal of the pontil scar is also wrong, I think (multiple grinding facets). Must admit to knowing absolutely nothing about Eda glass (Sweden). Wud you commit to giving an approximate date for this piece - assuming not W/Fs?
