By comparing the glow-curves we can calculate the dose of radiation absorbed by the piece during its lifetime.Radioactive measurements on the clay tells us how much radiation the piece is receiving each year.

The phenomenon of thermoluminescence was first described by the English chemist Robert Boyle in 1663.

It was employed in the 1950's as a method for radiation dose measurement, and soon was proposed for archaeological dating.

By the mid-1960's, its validity as an absolute dating technique was established by workers at Oxford and Birmingham in England, Riso in Denmark, and at the University of Pennsylvania in the U. The Research Laboratory for Archaeology at Oxford, in particular, has played a major role in TL research.

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.

When we receive your sample we must first prepare it for measurement.
