Tree ring and carbon 14 dating
Unfortunately there are no affordable direct methods for dating pigments, except in some cases as we will see later.Generally, for example, we can’t establish when a vermilion stroke was brushed onto a painting, but we can date most of the materials that the pigments are painted on.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.
Samples should not be exposed to heat and powdery examples should not be exposed to bright light.
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.
Thermoluminescent Natural radioactivity causes the number of trapped electrons to build up.
The older an object, the more trapped electrons it will have.
