Aplicaţii ale metodelor spectrale de analiză în caracterizarea ceramicii arheologice pictate cu negru

  • Subiect: The paper is focused on the GC-MS (gas chromatography coupled with mass spectrometry) technique analysis applications for the characterization of the black, shiny layer of organic nature, very well preserved, with which are painted the Neolithic ceramic fragments from the archaeological site of Porţ – Corău. The samples (weight is about 1 mg.) used for analyses were collected from the black layer on the surface of the ceramic fragments. GC-MS analysis results were correlated with data obtained by other methods of analysis, FT-IR and optical microscopy, confirming that the composition of the black layer is a mixture of birch bark tar with natural bitumen, birch bark tar being the predominant component. The results of the analysis had a special importance and were of great utility for both archaeological research and museums for the activity of restoration and preservation of artifacts.
