Whereas many other motifs of the Ravi Phase (Period 1) disappear in the later Kot Diji Phase (Period 2), the intersecting circle and fish scale motifs continued to be used, but they came to be executed in black paint on a red slip. In this image the lower sherds belong to the Kot Diji Phase (2800-2600 BCE) and the upper ones belong to the later Harappa Phase (after 2600 BC).
