The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available. It is an absolute dating method, and does not depend on comparison with similar objects as does obsidian hydration dating, for example. Most mineral materials, including the constituents of pottery, have the property of thermoluminescence TL , where part of the energy from radioactive decay in and around the mineral is stored in the form of trapped electrons and later released as light upon strong heating as the electrons are detrapped and combine with lattice ions.
By comparing this light output with that produced by known doses of radiation, the amount of radiation absorbed by the material may be found. When pottery is fired, it loses all its previously acquired TL, and on cooling the TL begins again to build up. Thus, when one measures dose in pottery, it is the dose accumulated since it was fired, unless there was a subsequent reheating.
