Ban Chiang

Discovered in 1957 it attracted enormous publicity due to attractive red painted pottery. The first scientific excavation was made in 1967 and uncovered several skeletons together with bronze grave gifts. Rice fragments have also been found, which prove that the bronze age settlement was made by farmers.

The first datings of the artefacts using the thermoluminescence technique resulted in 4420 BC[?]-3400 BC, which would have made the site the earliest ever farming culture of the world. However with the 1974/75 excavation enough material for radiocarbon dating became available, which resulted in much later dates - the earliest grave was at about 2100 BC, the latest of 1320 BC-1000 BC.
