Bunhap is a case used for storing face powder. It is round, shallow, and flat, and has a lid. Most bunhap were made of porcelain, but various other materials were also used, including earthenware in the Three Kingdoms period, celadon in the Goryeo era, and white porcelain in the Joseon Dynasty. Some bunhap were made of silver, wood, or stone. As for the celadon bunhap shown here, dots and lines were applied in black and white all over the surface using the paste-on-paste technique. The lines were drawn in a single stroke from the lid to the body.
