This energy is lodged in the imperfect lattices of the mineral's crystals.Heating these crystals (such as when a pottery vessel is fired or when rocks are heated) empties the stored energy, after which time the mineral begins absorbing energy again.But this method is also useful in many other disciplines.

In this work it is demonstrated that it is possible to obtain in the laboratory an artificial glow curve identical to the archaeological one.Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.Luminescence dating is particularly appropriate when radiocarbon dating is not possible (either where no suitable material is available or for ages beyond the radiocarbon age limit) or for applications affected by radiocarbon plateau effects ( 1700 AD, early Iron Age contexts, late glacial timescales) and when the relationship between the organic materials and the archaeological context is uncertain.

From the conditions of the laboratory experiment (temperature of irradiation and dose rate), under which the identity is achieved, it is possible to estimate the archaeological age of the sample.
