"Ming" - I think that is what the signature read as, I might be wrong.
This interesting pot seems to be part Royal Lancastrian uranium orange and part Royal Doulton Chang glazes. I guess a smaller Staffordshire pottery trying their hand at the fashionable art pottery during the 1920's. But calling it Ming was never going to convince anyone !!
I am not sure on the history of the factory or when this range was made - Can you help ?
