Ceramic vessel 8-J. Oppidum of Puente Tablas (Jaén, Spain)

Ceramic vessel 8-J from space J of the Sanctuary of the Iberian oppidum in Puente Tablas (Jaén, Spain).Wheelmade ceramic, oxidising firing. It has no decoration. The analysis of contents was carried out using GC-MS obtaining the peak of native sulphur (S8). The presence of sulphur in this ritual context is related to ceremonies for the purification of objects, spaces and atmospheres.

Content analysis

Destructive method for the identification of the total lipid profile: fatty acids, sterols, wax esters, fatty alcohols, triacylglycerols, etc. Any remains of soil were removed with an electric hand-drill. The sample was then grinded to the appropriate size in an agatha mortar (0.25 mm). Extraction with a mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction takes place at 70 ° C for 30 min using N,O-bis- (trimethylsilyl) trifluoroacetamide (BSTFA), with 1% trimethylchlorosilane (TMCS). The sample is solved in cyclohexane and then injected in GC-MS. Chromatographic separation is performed applying a adequate temperature program.

The analyses were performed using a using a gas chromatography equipment (model Thermo TraceGC Ultra) coupled to a Thermo DC Q II mass spectrometer. Autosampler Thermo Triplus (CICT, University of Jaén). The samples were introduced by on-column injection into a 15 m x 0.25 mm I.D. fused silica capillary column, coated with poly(dimethylsiloxane) stationary phase with 0.1 μm film thickness. Helium was used as the carrier gas (purity 99.99%).
