Chinese Persian Blue refers to a type of blue glaze used in traditional Chinese ceramics, especially during the Song Dynasty. It is known for its deep, lustrous blue color, which is achieved through the use of cobalt oxide as a pigment. The term 'Chinese Persian Blue' is sometimes used to distinguish it from other types of blue glazes, such as Japanese Arita Blue or Islamic Blue. This glaze is highly valued for its aesthetic qualities and historical significance in Chinese art and ceramics.
