Bowl decorated with peonies, Korea, Goryeo dynasty (918–1392), 13th century. Stoneware with inlaid and reverse-inlaid design under celadon glaze. H. 2 5/8 in. (6.7 cm), L.2016.43.7a, b. Photograph courtesy the National Museum of Korea

While the five peonies, each in a roundel, are inlaid in white and black, the surrounding scrolling pattern is achieved through the reverse-inlaid method: the background, rather than the design itself, is carved out and filled with slip. This combined technique creates a dramatic effect unique to Goryeo celadon.
