It is very rustic / brutalist in feel and was hand-thrown. It is made from gritty beige stoneware and has lots of horizontal ribbing with a dark brown and olive green glaze on the exterior, as photographed.
It is signed on the base: JF Coull.
I cannot find any reference to Coull working as a potter which is strange - but I have found out that he made a fancy wooden mount for a fine art glass plate blown by David Kaplan and engraved by Alison Kinnaird - which is on display in the Kelvingrove Museum in Glasgow.
Perhaps he changed his artistic direction at the end of the 70s.
The height of this unique studio vase is 12 inches and the diameter at the widest is 9 1/2 inches.
It weighs a stonking 5.7 kg. Never had a pot before which weighs quite so much. phew! It is even hard to lift!
Postage is going to be a bit more expensive due to the exceptional weight - and size of this pot. It is probably going to cost about £14 with Parcelforce48 - and of course for UK posting only.
