The loop on the long neck of this plain celadon bottle reflects the close relationship between metalwork and ceramic vessels in Koryo Korea. Metalwork vessels often had covers that were attached by a cord threaded through loops. Ceramics imitated this feature, although the loop was unlikely to have a practical use. The incised decoration on this celadon bottle includes clouds and lotus flowers, both popular designs found frequently on Koryo ceramics. While the bottle was buried in a tomb, its glaze reacted with its surroundings and consequently some areas have discoloured and degraded.
