I'm hoping someone will recognise the maker of my heavy glass bowl. It's rich brown / amber in colour, darker at the top and bottom.
It's 19cm wide and 8,5cm tall. The bottom is quite thick, with 2,5cm separating the base from the inside well. The base is completely flat with substantial wear. I can't make out if the edge has been beveled or not. The bowl weighs 1639g.
It's a well-made piece, but I'm afraid because it's so plain, it will be near impossible to find an attribution.
Thank you for looking.
