Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.Therefore, in archaeology, thermoluminescence dating works best for ceramics, cooking hearths, incidentally fire-cracked rocks, and deliberately fire-treated rocks, such as flint or chert.Is it possible to directly date pigments containing organic carbon, such as carbon black.

By looking at the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely.

The ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant.

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

Samples should not be exposed to heat and powdery examples should not be exposed to bright light.

Carbon-14 is radioactive, with a half-life of about 5,700 years.
