The form manifested in this large voluminous jar emerged as the production of buncheong ware began to accelerate. It has an outward-turning mouth, a long body and a shallow bottom. This appears to have followed the large-scale porcelain production style of the Yuan Dynasty in which porcelain ware was crafted by first molding a porcelain wall and then filling in the bottom and attaching a plate to complete the object. The top of the jar is inlaid with a large Anuruddha-head design, which is common in the blue-and-white porcelain ware of the late Yuan and early Ming Dynasties. A dragon is inlaid in the middle, with a lotus design at the bottom. The bright gray clay has been applied with a transparent light-blue buncheong glaze showing fine crackling. The design, composition, and technique reflect the characteristics of Yuan and Ming Dynasty pottery, but they also demonstrate the bold characteristics of porcelain made in the Joseon Dynasty.
