Sue, that is one gorgeous vase! :mrgreen: I don't think mine is from the same stable - the quality isn't as good on mine, but it does demonstrate what I was trying to describe re the resist / reactive layer thingie nicely. Thank you! :kissy:.
John, I agree they do look modern rather than older, but the base is polished flat and has some age wear to it so I'm thinking not terribly recent? (20th rather than 21st century?)
