The paper presents the chronology of the Holocene evolution of the Baltic Sea based on the optically stimulated luminescence (OSL) and radiocarbon dating methods applied to a core taken from the Arkona Basin.
The dating results were supplemented by grain size and geochemical analysis.
Generally speaking, when a sample is drilled and there is no information available about the burial environment, one may expect up to 40 per cent uncertainty.
This is adequate for the purposes of authentication where the question is whether the piece was fired in antiquity or recently; it will not differentiate, say, between a classic Greek terra cotta and a Roman copy.
Among the reasons for this is the small amount of material that may be taken for testing.
A leaflet from Daybreak describing the TL technique in more detail and giving a bibliography will be provided to interested persons. The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.
