PROSPECTING and DATING - Balázs ERDÉLYI: Authenticity research by thermoluminescent method of some works of art with unknown condition of finding from the antique selection of Museum of Fine Arts

The sample examined Year Age of history of art sample 1 1860-2090 ca. 1800 sample 2 1798-3019 (mean 2376) ca 2400-2500 sample 3 4069-4747 ca 2400-2500 sample 4 2989-3488 ca 2700-2800 The agreement between the dates for Samples 1 and 2 is conspicuous at first glance. In the case of Samples 3 and 4, on the other hand, the value measured is higher than the estimated age. This deviation can be explained by the difference in the sensitivity of samples, the inaccuracy of the estimated values of the gamma + cosmic doses and the alpha dose as well as the fact that in the case of the fourth sample the results are based on an insufficient quantity of material. Still, on the basis of these facts, the authenticity of the studied specimens can be ascertained. In case of two samples (No. 1 and 2) we can render the age of the objects with great certainty as well, while with the other two samples the stable TL-signs registered at high temperatures support originality.
