A specific type of pottery, typically porcelain but also stone and earthenware,
known for its jade green glazes. Celadon originated in China since the Shang dynasty but
became especially popular in other parts of East Asia such as Korea and Japan around the
time of the Song dynasty. Korean celadon, produced largely in the Goryeo dynasty,
boasted some of the most intricate and arguably striking examples of celadon pottery.
The celadon color is classically produced by firing a glaze containing small amounts of
iron oxide at high temperatures in a reducing kiln. The traditional celadon glaze applies
to a family of somewhat transparent glazes that are applied to stoneware or porcelain and
can appear yellow or bluish but the most desirable are the color of jade. Celadon is still
highly coveted today, given that many historical examples have been lost or destroyed
over time.
