What it is
The object is modelled in wax, coated in clay, the wax is melted out and metal is poured into the resulting cavity. It allows complex, hollow, single-use-mould shapes unattainable with two-part moulds.
The Nahal Mishmar hoard (c. 3700 BCE) and the Mehrgarh amulet (c. 4000 BCE) remain the best-documented examples of lost-wax casting in the Near East and South Asia, but archaeometallurgical analyses of the gold from the Varna necropolis (Bulgaria, c. 4550-4450 BCE) suggest the technique was also used there, which would make it the oldest known evidence if confirmed. Shang China preferred sectional clay moulds. Merged with «Mould casting and lost-wax casting» (duplicate, 23-09-2026).
What it led to
- Life-size bronze statuary and courtly art (Mesopotamia, Egypt, the Aegean)
- Complex mechanical parts: horse bits, harness fittings, fibulae, hinges
- Precision goldwork and prestige objects that distinguished elites
- An unbroken technical tradition down to Renaissance sculpture and industrial casting
- Prestige and cult metal objects that define the Chalcolithic elite
- Specialised metalworking workshops with closely guarded knowledge
- A technique that would dominate bronze sculpture to this day
