New metallurgical research conducted on a cache of 'Copper Hoard' artifacts found in the Chambal Basin has revealed that ancient Indian smiths were using sophisticated arsenical bronze alloying and cold-hammering techniques as early as 1500 BCE. The study confirms that these weapons were not merely ritual objects but highly functional tools of war and hunting.
Chemical profiling suggests that the copper was sourced from localized mines in the Aravalli Range, indicating a robust regional trade network. The findings push back the timeline for specialized metallurgical engineering in the Indian subcontinent, showing a mastery of material science long before the widespread use of iron.
