Other facilities not shown include a magnetic mineral separator and sensitive analytical apparatus for the measurement of the concentrations of the long-lived isotopes of U, Th and K which are the main contributors to the total stored energy in the material of the test object.
These have been associated with nearby charcoal which has been dated by H.
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.
The potential for using the thermoluminescence behaviour of sediments for dating them was first recognized by Soviet scientists G. In this review we describe the principles of TL dating, the various methods used, and contrast TL dating of sediments with the now well-accepted TL dating of pottery.
Since 1977 TL sediment dates have been published by six additional groups using a variety of methods.
