FACTORS AFFECTING THE VIABILITY OF THERMOLUMINESCENCE DATING OF GLASS
Résumé
The aim ofthis study is to achieve a better understanding of some of the factors that limit the thermoluminescence (T L) dating of glass. Using a 'model system' (lithium-disilicate samples having diflerent levels of crystallinity from 0 to 100 %), we show,first, that the TL of glass is reproducible onfy if the glass is not heated above its temperature glass transition and, second, that there is a clear connection between the TL sensitivity and the degree of crystallinity of the sample. We conclude that thermoluminescence is not a general dating methodfor archaeological glass, but it can be applied to particular glass samples that have specified characteristics.
