I received this from my in laws and dont have much information about it I know they had it for at least 20 years since I found old photos of it set up in their living room. Other then that I have no information about the pieces.
Dish appears to be made of red clay as I can see just a bit of red clay showing through in a couple of spots along the ruffled edge. The colors in the dish are kind of striated, there are shades of green, white and mauve down the sides of the dish but the base itself is very dark, either black or brown glaze. On the underside of the dish, in each corner, there is a little bump in the dish. There is a signature and a number on the dish but the signature, which is embossed, not painted is unreadable. Dish appears to be very well made
