Thermoluminescence dating of ceramics
In the majority of cases the pot will have been fired to about 800° C in antiquity when it was made, so that accumulation of stored energy begins anew from that time, and there is the possibility, first suggested by Daniels et al.
A director of Oxford Authentication® Ltd, Doreen Stoneham has been conducting authenticity tests since 1970, originally with the Research Laboratory for Archaeology at Oxford University, which pioneered the TL testing process.
TL Testing can be used to analyze fired pottery, earthenware and terracotta, and the casting cores of bronzes.
Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time.
XRF testing can be used to analyze virtually any material, but is most commonly used for metal analysis.
The scientific technique of thermoluminescence (TL) is used to evaluate the authenticity of archaeological pottery.
With any of our testing services, you can expect to receive your Test Results within 7 days or less from when we receive your item(s). Expedited testing available with results back in as little as 3 business days.
MOST clays contain a few parts per million of uranium and thorium and a few per cent of potassium, so that the body of an ancient pot receives a radiation dose of the order of 1 r./g/yr., mainly from α-particles.
XRF can be used to test a wide range of materials from ceramics to metals and glass.
