Abstract:	Electron probe analysis of the earliest metal found at the northeastern Thailand site of Non Nok Tha indicates that it is a bronze containing 4 to 6 percent tin. Recent thermoluminescence dates substantiate the presence of a well-developed bronze technology prior to 2300 B.C. and suggest a date of about 2700 to 2500 B.C. for the first appearance of bronze at the site.
