When pottery is fired, it loses all its previously acquired TL, and on cooling the TL begins again to build up.Heated stone material, such as hearths, pot boilers, and burnt flints, has been dated as well.Some regions known to present problems for TL include Indonesia and West Mexico; objects from these areas usually do not successfully yield TL dates.While not so accurate as radiocarbon dating, which cannot date pottery (except from soot deposits on cooking pots), TL has found considerable usefulness in the authenticity of ceramic art objects where high precision is not necessary.
Since the university laboratories involved with TL are research facilities, they generally will not accept art objects for authentication on a routine basis.
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.
