The correct option is Potter's wheel.
Explanation
The pottery of the Indus Valley Civilization (Harappan Civilization) represents a high degree of technical skill. The vast majority of pottery excavated from sites like Mohenjodaro and Harappa is wheel-made, with hand-made examples being rare.
Detailed Analysis:
- The Painted Earthen Jar found at Mohenjodaro is a prominent artifact illustrating Harappan craftsmanship.
- It was crafted using a potter's wheel, which allowed for symmetry and structural consistency.
- After the vessel was shaped on the wheel, it was fired in a kiln. The surface was typically treated with a red slip (red ochre), and designs were painted in black using pigments. This style is broadly categorized under Red and Black Ware.
- The designs often included geometric patterns, vegetation, and animal motifs.
Key Takeaway:
Harappan pottery is predominantly wheel-made, characterized by a distinct red background with black painted designs, reflecting advanced firing and shaping techniques.
