Begin your morning with a cup of strong coffee at a local coffee house, then set out with your guide to explore Gdansk's Old Town.The National Museum, located amidst the vaulted interiors of the former Franciscan monastery, houses one of Poland's best collections of art. Mary's Church, the largest brick gothic cathedral in the world, for a stunning panorama of the city below, then cruise downriver on a pleasure boat.The TL laboratory at Daybreak was established in 1977 to make TL available to the art community in general. Studies at Oxford back in the 70s on Romano-British pottery indicated that when all quantities entering the age equation are measured, the TL date of a single potsherd will typically fall within 15 per cent of the known date.When dates of a number of sherds associated together are averaged, the error is reduced typically to 7-10 per cent. The succeeding 30 years, and increased understanding of the dosimetry, have not brought much improvement. It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example). The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.The Beatles covered “Twist and Shout” early in their career.
Finally, one has to make the measurements regardless of whether the TL of the clay is well-behaved or not.
It was employed in the 1950's as a method for radiation dose measurement, and soon was proposed for archaeological dating.
By the mid-1960's, its validity as an absolute dating technique was established by workers at Oxford and Birmingham in England, Riso in Denmark, and at the University of Pennsylvania in the U. The Research Laboratory for Archaeology at Oxford, in particular, has played a major role in TL research.
Unfortunately, it is not possible to achieve this precision for the majority of art objects.
Among the reasons for this is the small amount of material that may be taken for testing.
