Ru?yao?style Celadon Folded?Rim DishBasic Archive? Suggested Period: Song?Jin Dynasty? Diameter: 7.87 inches (20.00?cm)? Height: 1.38 inches (3.50?cm)? Condition: Intact, no cracks, no hairline fractures, no later repairs. The glaze bears natural all?over crackle. Minor black firing pockmarks and kiln specks scattered across glaze surface. Faint wear to rim from long?term historical use; all conditions are original to the object.Object DescriptionThis is a Song?Jin?period Ru?yao?style celadon folded?rim dish. It features an everted folded rim, shallow curved wall and flat interior well. The substantial, neatly?formed ring base bears three tiny spur?mark firing scars, revealing pale?white body clay beneath — a characteristic full?glaze spur?supported firing technique of Ru?yao?related wares.The whole piece is covered in soft sky?celadon glaze with a subtle, mellow texture. Fine, spontaneous crackle runs throughout the glaze, created historically by thermal expansion differences between glaze and body, not damage. Minor pitting and dark specks are inherent kiln?firing marks. The rim glaze is slightly thinned, showing gentle wear accrued over centuries of handling.With an understated, elegant silhouette and well?proportioned form, it displays the classic pale sky?celadon tone associated with Ru?yao tradition. Retaining authentic firing and age?related surface traces, the dish offers value for academic reference and display?oriented collection.
