A new Palaeolithic discovery: tar-hafted stone tools in a European Mid-Pleistocene bone-bearing bed
Paul Mazza,Fabio Martini,Benedetto Sala,Maurizio Magi,Maria Perla Colombini,Gianna Giachi,Francesco Landucci,Cristina Lemorini,Francesca Modugno,Erika Ribechini +9 more
TL;DR: Two stone flakes partly covered in birch-bark-tar and a third without tar on it were discovered in fluvial gravel and clay in central Italy, in association with the bones of a young adult female Elephas (Palaeoloxondon) antiquus and several micromammals.
Journal ArticleDOI
Novel analytical methods for characterising binding media and protective coatings in artworks.
TL;DR: The aim of this paper is to review the most recent advances in the identification and determination of organic compounds present in art and art conservation materials.

GC‐MS analysis of penta‐ and tetra‐cyclic triterpenes from resins of Pistacia species. Part I. Pistacia lentiscus var. Chia
TL;DR: The aim of this study was to compare the qualitative and quantitative composition of triterpenes in the resin samples collected using the traditional and new liquid techniques, and examine whether the collection technique influences the contained triterpene skeletons in P. lentiscus var.
Journal ArticleDOI
Chemical study of triterpenoid resinous materials in archaeological findings by means of direct exposure electron ionisation mass spectrometry and gas chromatography/mass spectrometry
TL;DR: Although DE-MS was found to be a fast analytical tool, it failed to give any information on the presence of less abundant compounds when applied to mixtures of different materials: only mastic resin was found in the residues from the Roman censer, whereas GC/MS analysis identified the presenceof a vegetable oil from Brassicaceae seeds and Pinaceae resin.
Journal ArticleDOI
A GC-MS study on the deterioration of lipidic paint binders
TL;DR: In this article, the degradation of lipidic paint binders induced by irradiation with UV light (365 nm), exposure to urban air pollutants such as NOx and SO2 and combinations of the various treatments was investigated.

Characterisation of proteinaceous binders and drying oils in wall painting samples by gas chromatography–mass spectrometry
TL;DR: In this paper, a reliable analytical procedure has been developed for the characterisation of drying oils and proteinaceous binders in samples of painted artworks, which is based on microwave assisted acid hydrolysis followed by the extraction of the lipid component with diethyl ether.
