The correct option is Faience and terracotta.
Explanation
The Indus Valley Civilization (Harappan Civilization) shows significant archaeological evidence of textile production, particularly the spinning of cotton and wool. Artifacts associated with this domestic craft provide insights into the daily life and economic activities of the period.
Detailed Analysis:
- Archaeological excavations across various Harappan sites have yielded numerous spindle whorls, which are disc-shaped or spherical objects used to maintain the speed of the spindle during the spinning of thread.
- These whorls were primarily made of terracotta and faience. Faience is an artificially produced material made of ground sand or silica mixed with color and a gum, then fired.
- The widespread discovery of these artifacts in domestic settings indicates that spinning was a common household activity.
- While materials like shell, ivory, steatite, and metals (copper/bronze) were extensively used for ornaments, seals, and tools, the specific implement for spinning (the whorl) is characteristically associated with terracotta and faience in the Harappan context.
Key Takeaway:
Spindle whorls in the Indus Valley Civilization, used for spinning thread, were predominantly crafted from terracotta and faience.
