Samples should be placed in a polyethylene bag and sealed with electrical tape.To test the date we need to measure the sample’s thermoluminescence light which is then correlated to the accumulated dose of ionizing radiation.

Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.

Eventually, we will follow this formula to found out how many years old the sample is: Age (year) = accumulated dose / dose rate per year Thermoluminescence dating can be performed only in a specialized laboratory which will have a chemical section for the treatment of the samples with reagents and a radiation hazard restricted area.

Thermoluminescent Natural radioactivity causes the number of trapped electrons to build up.

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

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

Later heating releases the trapped electrons, producing light whose intensity is proportional to the amount of radiation absorbed.

Create fake pottery that will pass the thermoluminescence test One way to pass a fake through a TL test is to expose the newly-made pottery to a high dose of artificial radiation sources, thus fooling the measurement instruments.

However, producing fakes with this method calls for expertise on the subject, as well as expensive instruments.

The TL operator generally takes samples for dating from the bottom, avoiding damage to the image of the artwork.
