I knew I would be tempted to buy some more vases. I thought it would be interesting to compare the green one in the middle with the cobalt blue one on the left which I've had for a while. They are certainly very similar but not an exact match. The green one on the right doesn't sit quite right, a bit wobbly which makes me think hand-blown but no sign of a pontil mark on the base.
bases of the new vases, I guess the pontil mark on the right vase is polished or covered in some way, also no kick-up as I would have expected
