Authenticity testing of pottery using middle grains

The possibility of using middle size grains (diameter equal to 10-30 micrometer) in thermoluminescence (TL) dating of pottery was discussed. Data from fifteen specimens show that there is a good agreement between the estimated equivalent doses from the middle grain fraction and the fine grain (diameter equal to 2-8 micrometer) fraction of the same specimen. The natural TL intensity of the middle grain fraction is found to be twice higher than that of the fine grain fraction for the same sample. Hence, instead of fine grains middle ones can be used for authenticity testing of pottery. 采用中顆粒（φ１０—３０μｍ）制樣進行了陶器的年齡測定．對１５個標本同時以細顆粒樣品和中顆粒樣品做實驗，兩組結果一致．中顆粒的自然熱釋光強度高于細顆粒．link_to_subscribed_fulltex
