Small mouth, large shoulders, large belly, ringed feet, and small wounds on the mouth. The whole body is covered with white glaze, the glaze color is gray and densely covered with ice cracks. The bottom of the device is exposed. This batch of porcelain should come from the Chu Dau kiln site in Hai Duong Province (Hai Duong, lower reaches of the Red River Basin) in Vietnam. Its style is similar to the Hoi An Shipwreck (ca. late 15th to 16th century) unearthed in the 1990s.
