The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available. General references Links to other useful sites BACK TO HOME PAGE HOW DOES THERMOLUMINESCENCE DATING WORK?
As a crystalline material is heated during measurements, the process of thermoluminescence starts.
Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.
As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.
It will often work well with stones that have been heated by fire.
The clay core of bronze sculptures made by lost wax casting can also be tested.
Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.
