A groundbreaking excavation in Rajasthan's Shekhawati Region has revealed a 4,500-year-old Mineral Pigment Hub associated with the Indus Valley Civilization. This specialized industrial site contains intact stone grinding chambers and large deposits of processed iron oxide, malachite, and cinnabar, indicating a sophisticated system for mass-producing dyes and paints used in pottery and textiles.
The site is unique for its concentrated industrial layout, which is physically separated from residential quarters by a thick mud-brick wall. Archaeologists believe this suggests the existence of a highly organized pigment-makers guild that supplied decorative materials to major urban centers like Harappa. The presence of specialized storage jars containing refined powders indicates that the site functioned as a regional export center for high-value coloring agents.
