Thermoluminescence<br />
The technique known as <strong>the</strong>rmoluminescence is used<br />
to detect pottery forgeries. The process is fairly easy<br />
to underst<strong>and</strong>. Heat is applied to pottery <strong>and</strong> that<br />
causes it to produce <strong>the</strong>rmoluminescence, which is<br />
just light. The older <strong>the</strong> piece of pottery, <strong>the</strong> more<br />
<strong>the</strong>rmoluminescence it produces. In general <strong>the</strong><br />
amount of luminescence is directly proportional to <strong>the</strong><br />
original amount of radiation in an object. So any art-<br />
work that was claimed to have come from awhile ago<br />
could be subject to <strong>the</strong> testing if <strong>the</strong>re had been it had<br />
been exposed to any radiation previously.<br />
be made.<br />
