The correct option is The base of the pans.
Explanation
The pottery of the Indus Valley Civilization is primarily classified into plain ware and painted ware. While the painted pottery (Red and Black ware) is widely recognized for its geometric and animal motifs, incised ware constitutes a rare category within Harappan ceramics. The placement of decorations on these vessels followed specific stylistic norms.
Detailed Analysis
- Incised Decoration: Unlike painted designs which covered the outer walls, rims, and shoulders of jars and pots, incised decoration (patterns cut into the clay before firing) was restricted in its application.
- Specific Location: Archaeological evidence indicates that incised decoration was typically confined to the bases of the pans, almost always on the interior surface, and occasionally on dishes of offering.
- Contrast with Painted Ware: The rims, necks, and outer walls of jars and bowls were the standard surfaces for painted black designs on a red slip, rather than incised work.
Key Takeaway: While Harappan pottery is dominated by painted designs on the external surfaces of vessels, incised decoration is rare and specifically located on the bases of pans and offering dishes.
