A very remarkable jug. Bought from an American dealer in New York, thsi must be about 1760 or just slightly older. The most remarkable thuing is the colour of the glaze, in electric light it appears blue, but in sunlight appears green.
Very roughly potted, with no real finese on the finish, and the pot he holds is one of the biggest I've ever seen. I have seen vary similar jugs, again marked as very old, the one in Vics book I think is without a base. The closest I can put it with later toby jugs would be a Whieldon, the glaze is very similar, and the way the coat curves beyond the base is very characteristic of Whieldon.
