The light energy released is derived from electron displacements within the crystal lattice of such a substance caused by previous exposure to high-energy radiation.

This enables us to calculate the approximate age of the piece.

During its lifetime the pottery absorbs radiation from its environment and it is this which creates thermoluminescence.

The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.

We have 3 fully automated, computer operated Riso Minisys TL readers for measuring the TL.

Sample discs are mounted on a wheel and the readers are programmed to run heating and irradiation sequences.

The samples are irradiated in the laboratory with a known radiation dose and heated to produce another glow-curve.
