Thermoluminescence dating pottery

The research shows direct consequences resulting from the improper replenishment of starving beaches using fine sands.

Beach nourishment is a problem worldwide and receives large amounts of attention due to the millions of dollars spent yearly in order to keep beaches beautified for tourists, e.g., in Waikiki, Hawaii.

Both assumptions become less realistic with the passage of time.

Another problem with the TMRD is the calibration of the detector, since different crystals in an artifact can contain different amounts and/or types of luminescence material.

Quantum-mechanically, these states are stationary states which have no formal time dependence; however, they are not stable energetically.

This phenomenon has been applied in the thermoluminescent dosimeter, a device to measure the radiation dose received by a chip of suitable material that is carried by a person or placed with an object.The age range for pottery and other ceramics covers the entire period in which these materials have been produced.The typical range for burnt stone or sediment is from about 100 to 300,000 years.The particular advantage of luminescence dating is that the method provides a date for the archaeological artefact or deposit itself, rather than for organic material in assumed association.In the case of OSL sediment dating, suitable material (sand or silt-sized grains of quartz and feldspar) is usually available ubiquitously throughout the site.Thermoluminescence is a common geochronology tool for dating pottery or other fired archeological materials, as heat empties or resets the thermoluminescent signature of the material (Figure 1).Subsequent recharging of this material from ambient radiation can then be empirically dated by the equation: Age = (subsequently accumulated dose of ambient radiation) / (dose accumulated per year) This technique was modified for use as a passive sand migration analysis tool.(Figure 2).The error limits on the dates obtained are typically in the range of 5 to 10%.Our standard cost for OSL dating is £550 VAT per sample but prices can vary depending on the nature and number of samples (see our schedule of charges).When scientists pull pottery from the ground, they use heat or lasers to de-excite these electrons out of their trap states back to their original state. Scientists measure the amount of light to get the total measured radiation dose (TMRD).They divide this by an assumed radiation dose rate (RDR) to estimate the pottery’s age.


  1. Thermoluminescence TL dating is a technique that is based on the analysis of light release when heating. Pottery within a meter or so from ground level are typically

  2. Thermoluminescence dating definition, a method of dating archaeological specimens, chiefly pottery, by measuring the radiation given off by ceramic materials as they.
