We compared the geomagnetic field val-ues recorded by a metallurgical furnace against an updated SHAWQ2k-SH global model and a regional intensity curve, both ofwhich include, for the first time, high-quality intensity data from the Southern Hemisphere. Results place the furnace's last use in450–740 ce, and the decorated ceramic chronology at the site further constrains it to 570–740 ce, with maximum probability dur-ing the mid-late 600 s. This marks a significant methodological advance for Andean archaeometallurgy, addressing challengesposed by thermoluminescence and radiocarbon dating in the region.
