Hi Peter and all, I have 8 of these plates, they are 29.7 cm in diameter, they are hand painted, the foot looks to be 18th century, I am wondering if these could have been blanks that we're decorated at a later time, the fencai enamels are fairly thick except for the red it is flat to the touch but the crimson red is fencai enamel as the rest just the red is flat. or is the decoration 18th century, I am not sure.
