In the laboratory, the accumulated radiation dose can be measured, but this by itself is insufficient to determine the time since the zeroing event.The Radiation Dose Rate - the dose accumulated per year-must be determined first.Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. The technique has wide application, and is relatively cheap at some US0–700 per object; ideally a number of samples are tested. The destruction of a relatively significant amount of sample material is necessary, which can be a limitation in the case of artworks.The heating must have taken the object above 500° C, which covers most ceramics, although very high-fired porcelain creates other difficulties.It will often work well with stones that have been heated by fire.The clay core of bronze sculptures made by lost wax casting can also be tested.Ideally this is assessed by measurements made at the precise findspot over a long period.For artworks, it may be sufficient to confirm whether a piece is broadly ancient or modern (that is, authentic or a fake), and this may be possible even if a precise date cannot be estimated.

These imperfections lead to local humps and dips in the crystalline material's electric potential.

Oxford Authentication: Home - TL Testing Authentication 'Oxford Authentication® Ltd authenticates ceramic antiquities using the scientific technique of thermoluminescence (TL).

We just relisted our stunning Southern Oregon Gold Hill spectacular view property for sale with Chris Marshall of American Forest Management at (541) 664-9200. It is in one of the most in-demand rural areas in the country, and has really great access both to recreation and to midsize city resources. We are in the process of further reducing 404's and other link issues.

Its use is now common in the authentication of old ceramic wares, for which it gives the approximate date of the last firing.

An example of this can be seen in Rink and Bartoll, 2005.
