Heavy uranium green bowl with dark red insert in base and enclosed swirled bubbles. 2.7kg, diam 16cm, 6cm high. Bought at Dutch car boot sale so possibly Dutch. Must be pre-war and is vaguely similar to Copier’s Serica pieces of late 1930s though can’t find it in Complete Copier book. A friend says her grandmother had something similar.
Any help with ident would be much appreciated.
