Dating by thermoluminescence

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

It is also rare that any information about the radiation from the burial soil can be obtained, as art objects are usually thoroughly cleaned.This is adequate for the purposes of authentication where the question is whether the piece was fired in antiquity or recently; it will not differentiate, say, between a classic Greek terra cotta and a Roman copy.In some categories of objects, from China, for example, the actual age is quite precisely known for short-lived styles, and it is possible to work "backwards" to get information about the environment in many parts of the world, and some other parameters not usually measurable for art objects.It was employed in the 1950's as a method for radiation dose measurement, and soon was proposed for archaeological dating.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.
