Thermoluminescence dating is generally not very accurate.The accuracy of thermoluminescence dating is only about 15% for a single sample and 7 to 10% for a suite of samples in a single context.
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.
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.
