Maximum dating age equation
These will give an authentic date for a bogus object.It must be realized that TL dating is but one of the criteria for judging authenticity. General references Links to other useful sites BACK TO HOME PAGE HOW DOES THERMOLUMINESCENCE DATING WORK?In all, close to two dozen physical quantities must be accurately measured to establish the relationship between doses of different kinds of radiation and light output, and to compute dose rate.Unfortunately, it is not possible to achieve this precision for the majority of art objects.Among the reasons for this is the small amount of material that may be taken for testing.Some clays are hardly thermoluminescent at all; some may not have a straight-line relationship between dose and TL; spurious luminescence due to chemical or pressure effects may mask the radiation-induced TL; occasionally, a condition called "anomalous fading", where part of the TL is unstable, may lessen the accuracy of the dose measurement.
In some categories of objects, from China, for example, the actual age is quite precisely known for short-lived styles, and it is possible to work "backwards" to get information about the environment in many parts of the world, and some other parameters not usually measurable for art objects.
Heated stone material, such as hearths, pot boilers, and burnt flints, has been dated as well.
