Lot 4 plates calotte in old polychrome earthenware quimper? malicorne? rouen?

This set of 4 old hollow plates is superb. These ice plates are made of earthenware of the west certainly. No brand allows me to identify the place of production. Probably factories of malicorne or quimper perhaps, they are in pink earth covered with a white cover. The floral decorations are elegant, hand painted, in beautiful colors. Yellow, green, blue, red, some details are stenciled. These hollow plates present traces of ancient manufacture of the 19th century: irregularities of the cutlery, traces of the pernettes... Dimension: 20 cm. I am pointing out splinters.
