Jade-green glazed stoneware from Goryeo's kilns, prized in Song China and ranked among the world's finest ceramics.
See it on the Korean History map →What happened
Goryeo potters learned to make celadon (고려청자, Goryeo cheongja) from China's Yue kilns around the 10th century, and by the 12th they had perfected a translucent blue-green glaze that the Song envoy Xu Jing called 'kingfisher color' in 1123. They then developed sanggam inlay: carving designs such as cranes and clouds, filling them with white and black clay, then glazing and firing. The main kilns were at Gangjin and Buan on the southwest coast, which shipped wares by sea to Kaesong.
Why it matters
It is Korea's best-known contribution to world ceramics, and inlaid celadon was a Korean innovation with no close Chinese parallel.
How we know
Hundreds of kiln sites at Gangjin and Buan, cargoes raised from shipwrecks off Taean, Xu Jing's report, and pieces from tombs, several now National Treasures.
Still debated
When Korean celadon production began, in the 9th or 10th century, and whether Chinese potters came to Korea to start it, are debated.

▸Goryeo celadon flourished under GoryeoWell documented
The connection
Goryeo's Buddhist court and aristocracy were celadon's main customers, buying tea bowls, ewers, wine vessels and incense burners. Kilns at Gangjin and Buan shipped wares by sea to Kaesong. In 1157 King Uijong even roofed a pavilion with celadon tiles. Song Chinese writers ranked Goryeo's glaze among the best in the world.
When and how
10th to 14th centuries, peaking in the 12th, at kilns in Gangjin and Buan serving the court in Kaesong.
How we know
Xu Jing's 1123 report, Goryeosa entries, celadon roof tiles excavated at Gangjin, and shipwrecks found with cargo tags addressed to Kaesong officials.
Debates and open questions
How the kilns were organized, as state workshops or partly private producers, and how inlay techniques spread among potters are still studied.
▸Goryeo celadon declined after Mongol invasions of KoreaMostly agreed
The connection
Celadon peaked in the 12th and early 13th centuries. After the Mongol wars and under Yuan rule, the court's wealth and patronage shrank and taste turned toward Chinese porcelain. From the 1350s Japanese pirate raids hit the southwest coast, scattering potters from Gangjin and Buan. Late Goryeo celadon grew coarser and, in early Joseon, gave way to buncheong ware.
When and how
Mid-13th to late 14th century, at the coastal kilns of Gangjin and Buan and at smaller inland kilns.
How sure are we?
Dated pieces and kiln excavations show the decline in glaze and decoration; the Goryeosa records the pirate raids on the coast.
Debates and open questions
Historians differ on the main cause: the Mongol wars, changing Yuan-era taste, or later pirate raids. Some fine inlaid pieces date after 1231.
