Understanding the material sources and factory sites of the ancient Harappan civilization is crucial for studying their economy and trade networks. The Harappans were skilled craftsmen who utilized various stones like limestone and chert for tool production, especially blades.

Identifying Harappan Blade Factory Sites

Factory sites were specific locations where raw materials were processed into finished or semi-finished goods. For stone tools like blades, these sites were often located near the sources of suitable stone material.

The question asks about a factory site known for mass-producing limestone and chert blades and supplying them to Harappan settlements, particularly in the Sindh region.

Analyzing the Options

• Sukkur and Rohri Hills: This region, located in Sindh (modern-day Pakistan), is well-known for its extensive chert quarries. Archaeological evidence strongly suggests that the chert from the Sukkur and Rohri Hills was a major source for blade production during the Harappan period. Blades from these quarries have been found distributed across many Harappan sites, indicating a large-scale production and distribution network, especially serving settlements in Sindh and beyond.
• Khetri in Rajasthan: Khetri is primarily famous for its ancient copper mines. While copper was a vital resource for the Harappans, Khetri is not identified as a major center for limestone or chert blade mass production supplying Sindh settlements.
• Chagai Hills: Located in Balochistan, the Chagai Hills are known for various geological resources but are not specifically highlighted as the primary mass production site for the limestone and chert blades found widely distributed in Harappan Sindh settlements.
• Hills of Baluchistan: Balochistan has diverse mineral resources and was connected to the Harappan civilization through trade routes. However, the specific mass production site for limestone and chert blades supplying Sindh settlements is more precisely located in the Sukkur-Rohri region within Sindh itself.

The Significance of Sukkur and Rohri Hills Chert Quarries

The Sukkur and Rohri Hills possess vast deposits of high-quality chert, ideal for making sharp tools like blades. The Harappans established large-scale quarrying and workshop sites in this area. The sheer scale of the quarries and the evidence of extensive manufacturing waste indicate mass production. The widespread presence of Rohri chert blades at numerous Harappan sites, including those in Sindh, confirms its importance as a primary source and factory area.

Therefore, the site from which limestone and chert blades were mass-produced and sent to various Harappan settlements in Sindh is the Sukkur and Rohri Hills.

Additional Information: Harappan Craft Production

The Harappan civilization was characterized by sophisticated craft production. Besides stone blades, they excelled in:

• Metallurgy: Working with copper, bronze, gold, and silver to create tools, weapons, ornaments, and vessels.
• Bead Making: Producing beads from various materials like carnelian, steatite, lapis lazuli, shell, and faience. Chanhudaro was a major bead-making center.
• Seal Making: Crafting seals, often made of steatite, engraved with animal motifs and the Indus script.
• Pottery: Producing diverse pottery styles, including plain and painted wares.
• Shell Working: Utilizing shells to make bangles, beads, and inlay work.

These craft activities were often specialized, with certain sites focusing on particular crafts or processing specific raw materials obtained from distant sources, highlighting the extensive trade network of the Harappan civilization.
