Analytical Study of a Resinous Material Used as Sealing in Ancient Pottery Found in an Archaeological Site by Thermally Assisted Hydrolysis Methylation-Gas Chromatography-Mass Spectrometry, Vibrational Spectroscopy and Light Microscopy

A resin sample was found in the archaeological site of Lixus (Morocco), belonging to the second century BC.

Description
Summary:A resin sample was found in the archaeological site of Lixus (Morocco), belonging to the second century BC. The resinous material was found inside an amphora containing iron remains used in the plug as sealing material to hermetically close the pottery. The resinous sample was studied by several analytical techniques, as thermally assisted hydrolysis and methylation-gas chromatography-mass spectrometry (THM-GC-MS), Fourier transformed infrared spectroscopy (FTIR), and light microscopy. The material was identified as a Pinaceae resin. Therefore, a modern pine resin was also analyzed to consider the influence of aging in the archaeological sample. The ancient material was found not too oxidized, owing to the conservation conditions inside the amphora, protected from air and moisture.
