“…Our purpose was, first, to determine the natural substances preserved at the site of Cuciurpula by using a combination of structural and separative methods (DI EI–MS, GC and GC–MS: Regert and Rolando ; Regert et al . ; Regert , ). Beyond this objective, we aimed at understanding the role of the organic remains in improving and repairing pottery vessels.…”

In the north‐western Mediterranean area, the first Iron Age is characterized by intense contacts and cultural interactions between populations. Archaeological remains such as ceramic vessels or metal and glass objects are usually good indicators of the nature and the intensity of these exchanges, but can also be used to determine the way in which these populations were living at their time. In contrast, organic substances, despite their importance in a wide variety of activities, are rarely investigated due to their low degree of preservation. The recent discovery of a series of amorphous organic residues with adhesive properties at the site of Cuciurpula provided a unique opportunity to address questions related to the types of natural substances exploited, their provenance, their uses and their informational input to intercultural relationships. Our results, based on GC and GC–MS analysis of organic residues preserved at the site of Cuciurpula, provide strong evidence for the most southern use of birch bark tar in Western Europe, and also for the simultaneous use of this substance with pine resin. Beeswax was also identified in some samples. The combined study of residue composition, aspect and location on ceramic sherds reveals a variety of uses, highlighting a complex technical system.

“…6c) of the 7.0-7.3 min range of the TIC. This mass spectrum also showed molecular fragments due to monoglycerides, such as palmitic acid monoglyceride (m/z 313), oleic acid monoglyceride (m/z 339), and stearic acid monoglyceride (m/z 341), together with C 35 , C 37 , and C 39 diglyceril ions at m/z 552, 578, and 604 [38]. The peaks at m/z 262 and 264 may be assigned to acylium ions formed as fragments of glycerolipids that contain linoleic and oleic residues, respectively [37].…”

“…GC-MS is by far the most common analytical technique for wax characterisation in heritage objects. 2 The unknown composition and mixed nature of heritage wax samples may make it difficult to select the most appropriate experimental conditions and obtain a complete profile of the material but several studies have addressed this challenge. Distinguishing between different types of waxes in a GC-MS total or reconstructed ion chromatogram relies on the evaluation of the retention peaks in the chromatogram, corresponding to variations in the components of the wax (Fig.…”
