What is celadon?
Celadon is a blue-green glaze, often used on stoneware, a kind of ceramic. Celadons are named due to the greenish-blue color of their glaze. Their color can vary in tone from grayish to greenish depending on the composition of the clay. The color of celadon is achieved by placing a green-colored glaze over a gray clay body and the reaction of iron oxide when the vessel is fired in a reduction atmosphere.
