For instance, it is possible to date the wood support of a panel as well as canvas.The three most important dating techniques which are useful for the analysis of works of art are: Thermoluminescence (TL), Dendrochronology (DC), and Carbon 14 (C15). It dates items between the years 300-10,000 BP (before present).During its lifetime the pottery absorbs radiation from its environment and it is this which creates thermoluminescence.The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.
The accuracy of thermoluminescence dating is only about 15% for a single sample and 7 to 10% for a suite of samples in a single context.
Instead, a less sophisticated method that would deceive TL testing is to reuse original broken and unmarketable pieces.
Forgers commonly use the bottom of an original broken vessel, which has no commercial value, and make a new fake vessel on top of it.
54 samples were analyzed by radioisotope X-ray fluorescence; 51 of them come from Tel Jamous archaeological site in Sahel Akkar region, Syria, which fairly represent ceramics belonging to the Middle Bronze Age (2150 to 1600 B.
C.) and the remaining three samples come from Mar-Takla archaeological site fairly representative of the Byzantine ceramics.
