Story summary

The Kvemo Bolnisi workshop reanalysis shows copper smelters may have discovered iron production techniques.
It was not an early iron site; instead, it was a sophisticated copper facility using iron oxide as flux, which reshaped Bronze–Iron Age narratives.
The study highlights slag analysis, notes parallel methods at other sites, and the findings are published in the Journal of Archaeological Science.
