Thermoluminescence dating of the ancient Chinese porcelain using a regression method of saturation exponential in pre-dose technique

摘要

This paper studies the thermoluminescence (TL) dating of the ancient porcelain using a regression method of saturation exponential in the pre-dose technique. The experimental results show that the measured errors are 15 percent (+ - 10) for the paleodose and 17 percent (+ -10) for the annual dose respectively, and the TL age error is 23 percent (+ -10) in this method. The larger Chinese porcelains from the museum and the nation-wide collectors have been dated by this method. The results show that the certainty about the authenticity testing is larger than 95 percent, and the measurable porcelains make up about 95 percent of the porcelain dated, it is very successful in discrimination for the imitations of ancient Chinese porcelains. This paper describes the measured principle and method for the paleodose of porcelains. The TL ages are dated by this method for the 39 shards and porcelains from past dynasties of China and the detailed data in the measurement are reported.
