This jar is characterized by four square lugs on its shoulders and a petal-shaped flange around the lower body. The white body is covered with transparent lead glaze and with eight stripes of bright green lead glaze from the neck to the lower body.
A jar with this shape was excavated from a Eastern Wei tomb dating from the first half of the 6th century in Anyang, Henan province. According to the archaeological reports, the surface the excavated material was covered with greenish glaze on white slip. ‘Greenish glaze’ is probably a lead glaze that was intended to be transparent but was colored as a result of remaining impurities. Judging from this excavated example, this shape has already appeared in Eastern Wei. White clay and copper coloring techniques appeared in Northern Qi. After those appearance or development of techniques, It is thought that this work came to be made.
