The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.

When pottery is fired, it loses all its previously acquired TL, and on cooling the TL begins again to build up.The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.By measuring the TL, we can calculate how much radiation has been absorbed and use this information to calculate the approximate age of the pottery.When a small sample of ancient pottery is heated it glows with a faint blue light, known as thermoluminescence or TL.During its lifetime the pottery absorbs radiation from its environment and it is this which creates thermoluminescence.
