Datation thermoluminescence
WebThe thermoluminescence dating. consists in measuring the intensity of the light emission which emanates from a tiny sample taken from a ceramic object after having warmed it to a temperature of about 500° C. Knowing that the luminescence is proportional to the time elapsed since the manufacture of the ceramic, the age of the latter can be obtained by … WebThe phenomenon of thermoluminescence corresponds to the light given out when a transparent crystal is heated after it has been exposed to ionizing radiation. It has been …

It is a type of luminescence dating . The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. See more Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) … See more Another important technique in testing samples from a historic or archaeological site is a process known as thermoluminescence … See more Optically stimulated luminescence dating is a related measurement method which replaces heating with exposure to intense light.
