A jar made in the early Joseon dynasty. It has a slightly elongated body with a bulgy body and an outward mouth. The arabesque pattern is drawn using the local cobalt pigment produced on the Korean peninsula, and its characteristic brushwork resembles the Gyeryongsan type works.

The local cobalt was used in several kilns from the late 15th to the 16th century, including the Daomali kiln in Guangzhou. However, because the colouring is not as good as that of cobalt produced in China, many of the pieces are merely samples or prototypes, and, likely, this product was also a prototype.

There are some minor glaze flakings on the rim. There are no other noticeable defects. It is housed in a box with a missing string and is inscribed “Early Gyoryongsan Jar.
