This bowl measures 12 cm high x 15.5 cm diameter (= almost 5 by just over 6 for the non-metric). It has a polished pontil mark and its most striking feature is the sea-green colour. The bottom scratch could - conceivably could - hide a signature - but I haven't fount it yet.
I have seen this colour before - but cannot remember if it was Orrefors, or Sea, or even Leerdam.
Does anyone recognise it - please?
