These will give an authentic date for a bogus object.
It must be realized that TL dating is but one of the criteria for judging authenticity.
Warning about fakes using ancient materials What about airport x-rays and radiography? Thus, when one measures dose in pottery, it is the dose accumulated since it was fired, unless there was a subsequent reheating.
When pottery is fired, it loses all its previously acquired TL, and on cooling the TL begins again to build up.
It was employed in the 1950's as a method for radiation dose measurement, and soon was proposed for archaeological dating.
Among the reasons for this is the small amount of material that may be taken for testing.

The clay cores from lost wax metal castings may readily be tested. 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.
