Celadon
Celadon () is a term for pottery denoting both wares glazed in the jade green celadon color, also known as greenware or "green ware" (the term specialists now tend to use), and a type of transparent glaze, often with small cracks, that was first used on greenware, but later used on other porcelains. Celadon originated in China, though the term is purely European, and notable kilns such as the Longquan kiln in Zhejiang province are renowned for their celadon glazes.
