What an archaeologist would be able to measure using this technique is the last time the vessel was heated above 500 degrees Celcius, either at the time the vessel was first fired or the last time it was heated if it was used as a cooking vessel.In the laboratory, the release of electrons can be induced through heating or the use of a laser beam.This energy is in constant motion within the minerals or sherds.Most of the energy escapes as heat, but sometimes this energy separates electrons from the molecules that make up the minerals or ceramics.

The microscopic structure of some minerals and ceramics trap nuclear radioactive energy.The process of firing the vessel releases the trapped electrons (energy), and resets the thermoluminescence clock to zero.The process of accumulation of electrons (energy) and then release when heated occurs every time the ceramic vessel is reheated.Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.
