Hi
I have a couple of quite old vases quite heavy approx 930gms each clear lower half turning to green at top, they have bubble inclusions in the top third , you can feel the bubbles from the inside, they have a polished pontil, no makers mark , I have been told they may be Richardson, but I am unsure myself, although they did come from Stourbridge, I do not think there worth much as they both have some water damage and a few scratches
many thanks roy
