Story summary

Cranfield University researchers reinterpret a 3,000-year-old site at Kvemo Bolnisi, Georgia, as a copper workshop.
It used iron oxides to intensify copper yields, challenging earlier iron-smelter assumptions.
Initial excavations in the 1960s misidentified the site, prompting a shift to a gradual iron-production narrative.
Researchers urge caution and recommend reexamining other copper-smelting sites to understand iron's emergence.
