Cheers and thanks for the additional info Robert.
At first, I thought some amateur had had a go at cut the vase as the two groves down the side are a little rough and the surface has an odd, almost matte finish. Nevertheless, I love the colours.
On the link Rocco posted, the vase on the bottom right is another vase I love. I saw one at an auction a few years ago and still wish I had carried on bidding for it, I didn't know what it was at the time but the simple shape and colours were pretty mesmerising.
and for you, Anik ;-)
