It is caused by pre-irradiation of the material inducing defects which are removed by the heat, the energy released appearing as light: used in archaeological dating Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.During its lifetime the pottery absorbs radiation from its environment and it is this which creates thermoluminescence.The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.

phosphorescence of certain materials or objects as a result of heating.

We have 3 fully automated, computer operated Riso Minisys TL readers for measuring the TL.

Sample discs are mounted on a wheel and the readers are programmed to run heating and irradiation sequences.

Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology.

On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations.
