Three lumps with teeth imprints and a larger amorphous piece from the Late Neolithic layers have been studied by X-ray computed micro-tomography (microCT) and synchrotron Fourier-transform infrared spectroscopy (FTIR). FTIR spectra match well that of birch bark tar and microCT of the larger piece has revealed a rolled-up structure likely corresponding to bark rolls. The lumps of birch pitch were probably chewed to soften the tar prior to be used as hafting adhesive or therapeutic substance. The rolled-up inner structure of the larger piece and the remains of birch bark tar and abundant charcoals on its surface suggest it probably corresponds to a rare waste product from allothermic tar production.

Fundamental parameters such as the high photon flux, the small source size and the low divergence typical of synchrotrons make it a very efficient source for a range of advanced spectroscopy and imaging techniques, adapted to the dishomogeneity and complexity of the materials under study. The continuous tunability of the source (from infrared to X-rays) is essential for techniques based on a fine tuning of the probing energy to reach high chemical sensitivity such as XANES, EXAFS, STXM, UV/VIS spectrometry. Moreover, the small source size attained in the vertical plane leads to spatial coherence of the pho...

This is part of a project funded by the Region Friuli Venezia Giulia (Italy) and the ICTP, which aims to develop innovative X-ray analytical tools for noninvasive studies of cultural heritage objects and palaeontological remains. The X-ray instruments at MLAB are also used for hands-on training activities involving students and scientists from developing countries. The MLAB analytical tools complement the microtomography instruments available at Elettra-Sincrotrone Trieste. Examples of our first studies in archaeological and palaeontological applications are presented here.
