By comparing this light output with that produced by known doses of radiation, the amount of radiation absorbed by the material may be found.

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).

A set of criteria for acceptable dates is proposed. 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.These complicated factors are analyzed and discussed.Therefore, although ceramic TL dating can in general solve the problem of authentication of ancient ceramics, there are still complexities that require further research and study.
