Age dating limit
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.
By the mid-1960's, its validity as an absolute dating technique was established by workers at Oxford and Birmingham in England, Riso in Denmark, and at the University of Pennsylvania in the U. The Research Laboratory for Archaeology at Oxford, in particular, has played a major role in TL research.Heated stone material, such as hearths, pot boilers, and burnt flints, has been dated as well.Some regions known to present problems for TL include Indonesia and West Mexico; objects from these areas usually do not successfully yield TL dates.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.
It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example).
