Carnelian
Explanation
The Harappan civilization (Indus Valley Civilization) possessed a highly developed craft industry. Bead-making was one of the most significant specialized crafts, with products exported to regions as far as Mesopotamia. Specialized centers such as Chanhudaro and Lothal were dedicated to this industry.
Detailed Analysis:
- Carnelian: This was the primary stone used to manufacture the distinctive red beads associated with Harappan culture. Carnelian is a semi-precious stone. The Harappan craftsmen developed a complex technology to produce these beads, which involved firing the yellowish raw material at various stages of production to achieve the characteristic red colour. They also utilized specialized drills (made of ernestite) to bore holes into these hard stones.
- Lapis Lazuli: This is a deep blue metamorphic rock. While used in Harappan jewelry, it was not the material for the red beads. It was primarily sourced from Shortughai in Afghanistan.
- Jasper and Quartz: These materials were also used for bead making, along with steatite, agate, and faience. However, the specific reference to "distinctive red beads" points directly to the specialized Carnelian industry.
Key Takeaway:
Carnelian was the specific stone used for the famous Harappan red beads, produced through advanced heat treatment techniques at specialized craft centers like Chanhudaro and Lothal.
