Abstract:
The development of analytical research in recent decades, at the edge between analytical chemistry and archaeology, provides new methods for the study of organic residues that are usually highly sensitive to natural decay. Using Nuclear Magnetic Resonance (NMR) and Gas Chromatography-Mass Spectrometry (GC-MS), it is now possible to chemically identify a series of natural substances preserved in archaeological environments. This paper presents a protocol to detect natural compounds, such as olive oil, from amorphous organic residues discovered inside the pores of prehistoric pottery from the Early Bronze Age settlement of Castelluccio (Noto, Italy), and dated to the end of the 3rd and the beginning of the 2nd millennium Before the Common Era (BCE).
