In the Swat region, different types of pottery were associated with various archaeological periods:

1. Black Burnished Ware: This type of pottery is typically associated with the early historic period in the Swat region. It is often linked to the Gandhara Grave Culture, which dates back to around 1500 BCE to 500 BCE.

2. Fine Gray Ware: This ware is generally found in the context of the later historic periods, particularly during the time of the Indo-Greek and Kushan periods, which span from approximately the 2nd century BCE to the 3rd century CE.

3. Gritty Red or Buff Ware: These types of pottery are often found in the context of the early historic and protohistoric periods. They are associated with the Gandhara Grave Culture and continue into the early historic periods, overlapping with the time frames of the black burnished ware.

These pottery types help archaeologists understand the cultural and chronological context of the Swat region's ancient inhabitants.
