This is a "Seiji" (celadon) plate with a beautiful pale blue-green glaze, featuring a delicate chrysanthemum pattern carved in intaglio. Characteristics of Celadon: Originating in China, celadon is characterized by its unique blue-green hue, achieved by firing with an iron-containing glaze at high temperatures. Surface Technique: The fine, crack-like pattern seen on the surface is called "kannyu" (crazing), and it is one of the deeply flavorful decorative elements of celadon, created by the difference in shrinkage rates between the glaze and the body. Design: This is a formal piece of pottery with a chrysanthemum motif placed in the center. The plate has been stored in a wooden box for many years. However, the wooden box was damaged during photography, so the plate will be carefully packed and shipped in a separate box.
