A preliminary study on thermoluminescencehigh-temperature peak dating of forcelain

Thermoluminescence dating technique is only one dating method which can direclty determine the age of old porcelain baking(or the last high-temperature event). Stoneham of Oxford University has firstly used the thermoluminescence dating method with pre-dose technique for determining porcelain samples in 1983. After then,the thermoluminescence pre-dose technique for dating of old porcelain was developed in many laboratories.But the thermoluminescence high-temperature signal(over 250℃)was not be studied in most laboratories and thermoluminescence high-temperature signal dating of porcelain was not reported in literature till now. In order to improve overall level and reliability of thermoluminescenec dating of porcelain,a preliminary study of the characteristics of thermoluminescence high temperature peak and feasibility of dating of porcelain were conducted. The result is described in the paper. There is a thermoluminescence high temprature peak in porcelain,and the high temperature signal can be used to date porcelain.
