Identification of North European archaeological charcoal and wood with rapid spectroscopic methods

Beskrivelse

The project aims to develop a robust spectroscopic method for wood identification of archaeological charcoal and wood. In addition, to test the method in a wood resource analysis of Viking Age charcoal, sampled from
houses and pits used by the aristocratic/kingly elite in Tissø and by the people living under more simple conditions at Dalby Hals in the harbor belonging to the elite at Tissø. The hypothesis is that Near Infrared spectroscopy (NIR) and Fourier-Transform Infrared spectroscopy (FT-IR) can be used to species identification of native North European angiosperms and that it is possible to identify archaeological wood and charcoal samples of same origin. The two spectroscopic methods have a substantial potential as a supplement to
traditional anatomical wood species identification as they are fast and low cost methods. Establishment of a comprehensive database of spectra of reference material that spans the variation in archeological material, thoroughly prepared chemometric classification tools, and a standard procedure for the analysis technique will increase the number of samples that can be identified in a given time span significantly. This will greatly benefit the outcome of information on wooden sample material from archaeological excavations.
