"This raises a provoking question: why are the very oldest trees the most complicated?
Therefore, in archaeology, thermoluminescence dating works best for ceramics, cooking hearths, incidentally fire-cracked rocks, and deliberately fire-treated rocks, such as flint or chert.Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, some of which are trapped at imperfections in the crystal lattice.Later, heating releases the trapped electrons, producing light.Create fake pottery that will pass the thermoluminescence test One way to pass a fake through a TL test is to expose the newly-made pottery to a high dose of artificial radiation sources, thus fooling the measurement instruments.
However, producing fakes with this method calls for expertise on the subject, as well as expensive instruments.
Measuring the intensity of the luminescence can determine how much time has passed since the last time the object was heated.
