Thank you for viewing. This is a white porcelain chrysanthemum-shaped plate purchased from an antique shop. It has a thin construction, and combined with the chrysanthemum shape, it is very elegant. The center design looks like a small four-petaled flower, or perhaps a five-petaled flower with the white space interpreted as curled petals. What is the design at the base of the center? It looks like a lip. There are small sizes of the pattern in places. Both the large and small have the same regularity, but I don't know the reason. The larger plate has a chip on the rim. There are extremely slight scratches. Please take a good look at the images. Other than that, it may be kiln marks. Sizes: Small: Width: 12.5 cm Height: 2.3 cm Large: Width: 14 cm Height: 3 cm
