WARNING ABOUT FAKES USING ANCIENT MATERIALS Recently there has been a spate of forgeries devised expressly to attempt circumventing TL dating.

These use pottery of the appropriate period to construct objects.

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.

It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example).

The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.

Drilling, the usual method of sampling, introduces some uncertainty.

It is also rare that any information about the radiation from the burial soil can be obtained, as art objects are usually thoroughly cleaned.

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.

Heated stone material, such as hearths, pot boilers, and burnt flints, has been dated as well.
