The Forged Foundation
An interactive journey into the thousand-year legacy of Kui iron smelting and its enduring influence on Cambodia.
Who were the Kui?
The Kui people, historically called "Kamaen-boran" or "ancient Cambodians," are an indigenous group renowned for their mastery of metallurgy. For over a millennium, they were the primary producers of iron in the region, a skill that made them not a peripheral tribe, but a foundational pillar of Cambodia's technological and economic power. Their ability to transform earth into iron was a critical engine for the rise of great empires.
A continuous iron smelting tradition from the 7th to the 20th century.
The Alchemy of Iron
The Kui developed a sophisticated, labor-intensive process, turning ore from Phnom Dek ("Iron Mountain") into high-quality iron bloom. This was a complex transformation from earth to metal, steeped in specialized knowledge and likely accompanied by unique spiritual rituals.

Forging an Empire
The iron produced by the Kui was the strategic resource that powered the Khmer Empire. From the tools that built the temples of Angkor to the weapons that equipped its armies, Kui iron was indispensable.

Centuries of Production
Archaeological evidence from key sites reveals a long and complex history of iron production.
The Fading Glow
After millennia of continuous production, the Kui smelting tradition declined rapidly in the mid-20th century, driven by the influx of cheaper, mass-produced foreign metals.
Craftsmanship Reimagined
While smelting from ore is a lost art, the legacy of Kui metalworking persists. The craft has transformed, with modern artisans focusing on blacksmithing—shaping scrap and imported metal.
