This is a white pottery jar from the Shang dynasty. The tradition of firing white pottery is believed to have developed in the Neolithic period and continued until the late Shang, around 1100 BCE. However, new research suggests that white pottery production may have stopped during the mid-Shang, before it was revived again in the late Shang. White pottery is only found in tombs of wealthy aristocrats; the jar in front of you is a rare conserved example of this.
Look at the way the jar is decorated. Commonly seen on bronze vessels, the decoration on the neck consists of kui- dragon patterns. The body is further embellished with zigzag patterns, which are typically found on pottery from this period.
Scholars believe that white pottery vessels like this were not used for sacrificial purposes but were instead used to display the relationship between tomb occupants and their ancestors.
