Explanation:

The Harappan pottery is bright or dark red and uniformly sturdy and well baked. It consists chiefly of wheel made wares both plain and painted. The plain pottery is more common than the painted ware. The plain ware is usually of red clay with or without a fine red slip.
The painted pottery is of red and black colours. Several methods were used by people for the decoration of pottery. Geometrical patterns, circles, squares and triangles and figures of animals, birds, snakes or fish are frequent motifs found in Harappan pottery. Another favourite motive was tree pattern. Plants, trees and pipal leaves are found on pottery.
