The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.
Most mineral materials, including the constituents of pottery, have the property of thermoluminescence (TL), where part of the energy from radioactive decay in and around the mineral is stored (in the form of trapped electrons) and later released as light upon strong heating (as the electrons are detrapped and combine with lattice ions).
It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example).
The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.

Different materials vary considerably in their suitability for the technique, depending on several factors. Should I be concerned about artificial irradiation? If the radioactivity of the pottery itself, and its surroundings, is measured, the dose rate, or annual increment of dose, may be computed. Warning about fakes using ancient materials What about airport x-rays and radiography? Thus, when one measures dose in pottery, it is the dose accumulated since it was fired, unless there was a subsequent reheating. For roughly 000, maybe take 00, one can get either a AE101R Corolla Seca or a 1.3L Echo hatch. Actually, most of the AE101's would be over 100000km. I guess that's why I didn't like the sedan version- it's a mini Camry. Clutch and gear change in both feel about the same. Echo is smaller and lighter, but all that Rn D at Toyota should make it safe. That means 1996-1998 for the Corolla, and 1999-2001 for the Echo. It's awesome to see the odometer tick over from 99999 to 100000 =P. I don't know why but the front of the AE101 reminds me of the Camry of similar age. that's butt ugly, and more expensive because it has a larger engine. I can get around 400km with 35L light driving shifting at 2500rpm. I'd say about the same, after you weigh up pros and cons. I don't know about the Echo but it does have airbags.

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.
