Celadon is a type of ceramic glaze that originated in East Asia, particularly in China during the Tang Dynasty. It is known for its distinctive pale green color, which is achieved through the use of iron oxide in the glaze. Celadon pottery often features intricate designs and is highly valued for its beauty and craftsmanship. The term "celadon" can also refer to the type of pottery itself, which is typically stoneware. This style became popular in various regions, including Korea and Japan, where artisans developed their own unique variations. Celadon pieces are often used for both functional and decorative purposes.
