Oooh nice vase — I just love these big chunky monsters. Anyway, I hate to enter a "mine's bigger than yours" debate :shock: but I have one that's about 7" (18cm) across from point-point and 4ΒΌ" (11cm) tall. A rather mundane smoke-grey sommerso so nowhere near as nice as yours and I do personally favour the green/yellow colour

I've no idea to maker and won't even bother suggesting Flavio Poli for Seguso, but Cenedese and Nason both made these styles, I believe, although Nason appear to be commonly in the less attractive colours (like mine). But I think the style was widely copied on Murano – imitation is the sincerest form of flattery...
