black glazed ware en

Refers to ceramics coated with a black glaze high in iron content. It is distinct from wares with a body painted with iron pigment under a transparent glaze. Its production increased in China after the third century along with celadon. It had been introduced to Korea by the fourth century, particularly in the territory held by the Baekje Kingdom during the Three Kingdoms Period. Black-glazed ware was produced in Korea in small quantities alongside celadon during the Goryeo Dynasty and along with buncheong sagi (buncheong ware) and white porcelain in the first half of the Joseon Dynasty. Some kilns specialized in black-glazed ware during the late Joseon period, along with limited quantities of white porcelain. Before the modern era, its black color was likened to crows, and the ware was therefore also called "oja" (literally, crow ware) with typical forms being bottles and jars.
