They have established that their technique can be used to determine the age of objects up to 2,000 years old but believe it has the potential to be used to date samples around 10,000 years old.

Fired clay ceramics start to react chemically with atmospheric moisture as soon as it is removed from the kiln.Even when the absolute dates are available, we have to supplement the information with relative dating.The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.Luminescence dating is particularly appropriate when radiocarbon dating is not possible (either where no suitable material is available or for ages beyond the radiocarbon age limit) or for applications affected by radiocarbon plateau effects (e.g.post 1700 AD, early Iron Age contexts, late glacial timescales) and when the relationship between the organic materials and the archaeological context is uncertain.In these conditions, radiocarbon dating of ceramic fragments is the only reliable way to obtain of radiocarbon dates from a specific cultural phenomenon. By the way additives into clay could be different origin like vegetables, humus and lake sediments - i.e. RADIOCARBON, Vol 51, Nr 2, 2009, p 795-801 A Vybornov, G Zaitseva, N Kovaliukh, M Kulkova, G Possnert, V.
