From this time on, electrons start to build up again because of the natural radioactivity.

When the sample is heated in the lab, it releases thermoluminescence light.

Later, heating releases the trapped electrons, producing light.

Electron trapping Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, where some are trapped at imperfections.

Therefore, thermoluminescence dating is actually determining the last time a crystal was heated and electrons were released.

The minerals that are used for thermoluminescence dating are mainly quartz and feldspar.

The older an object, the more trapped electrons it will have.

When the object is heated to 350 degrees Celsius the trapped electrons are released and this is called a clock resetting event.
