Description
Keishiro Azami and co-authors read centuries of change in Angkorian ironmaking from the slag left behind in northern Cambodia. Khmer builders raised vast monuments with iron tools, and slag mounds near the sites mark a major iron region of the empire. How the craft itself changed over time was unknown.
Their 2025 study tests slag and ore chemistry along with isotope fingerprints. Early smiths blended laterite and umber ores with manganese and sulphide additions, winning high yields as empire demand peaked. After the late thirteen hundreds, the mix shrank to plain ores and yields fell as the empire waned. The fine method died out, with at most a fragment passed on elsewhere.
