The amount of light produced is a specific and measurable phenomenon. Because this accumulation of trapped electrons begins with the formation of the crystal structure, thermoluminescence can date crystalline materials to their date of formation; for ceramics, this is the moment they are fired. The major source of error in establishing dates from thermoluminescence is a consequence of inaccurate measurements of the radiation acting on a specimen.
The complex history of radioactive force on a sample can be difficult to estimate. However, thermoluminescence proven acceptable in providing approximate dates in the absence of more exact measures. Thermoluminescence Dating Thermoluminescence can be used to date materials containing crystalline minerals to a specific heating event. Exempted from this legal reservation are brief.

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). Aug 24, Two forms of luminescence dating are used by archaeologists to date events in the past: thermoluminescence (TL) or thermally stimulated luminescence (TSL), which measures energy emitted after an object has been exposed to temperatures between and °C; and optically stimulated luminescence (OSL), which measures energy emitted after an object has .

Assuming the minimal feasible uncertainties in systematic errors associated with both dose rate (conversion factors) and equivalent dose (source calibration). Thermoluminescence Dating Thermoluminescence can be used to date materials containing crystalline minerals to a specific heating event.

M.J. Aitken, in Encyclopedia of Materials: Science and Technology, Luminescence. There are two variants of luminescence dating: thermoluminescence (TL) and optically stimulated luminescence (OSL), or optical dating. The dating information is carried in the form of trapped electrons; these are electrons which have been ionized by nuclear radiation and which . Thermoluminescence (called TL) dating was invented around by physicists, and is based on the fact that electrons in all minerals emit light (luminesce) after being heated. It is good for between about to about , years ago, and is a natural for dating ceramic vessels. Thermoluminescence, or TL, has been used since the s to determine the approximated firing date of pottery and burnt thermoluminescence materials. TL has a wide dating range; it has been used to date ceramics from a few hundred years old to geologic formations that are half a million geological old.
