Thank you very much, Judy! I had no idea what the platter was - because I could not read the backstamp. The other piece that I have with me is more readable, clearly marked "Scinde" and also another less readable mark . . . perhaps S.and G. Alcock on the bottom line of a stamping. I believe it is a tall (8") sugar bowl, and although the glaze is very dark, there are no imperfections. I photographed both sides of the piece and the bottom. I'm thinking that maybe this, like the Sobraon platter is mid-1800s. I would certainly consider selling both the platter and the sugar bowl, but I am not an antiques professional, so could only go by similar pieces in similar condition previously sold. My real collection is Cornish Blue Kitchenware that was purchased by my late grandmother when she was in England in the early 1950s or late 1940s, and later pieces that my father brought me when he traveled to Europe. I went to the site of the old T.G. Green pottery while I was in England last year and also met the curator of the T.G. Green museum, a lovely man by the name of Iain Hambling.
