Ceramic vessel 30-U. Oppidum of Puente Tablas (Jaén, Spain)

Ceramic vessel 30-U from room U of the Sanctuary of the Iberian oppidum in Puente Tablas (Jaén, Spain). Wheelmade pottery, oxidising firing, it does not present decoration. Content analysis using GC-MS identified the presence of native sulphur (S8) and beeswax markers: alkanes nC27 to nC31, long chain alcohols C24 (OH) to C34 (OH), palmitic acid wax esters W40-W52 and hydroxymonosters W (OH)40–W(OH)46.

Pottery. Lipids 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 the mixture chloroform/methanol (CHCl3:MeOH) (2:1 v/v) assisted by ultrasound. Derivatization of lipids to trimethylsilyl derivatives (TMS). The reaction tales place at 70 ºC 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 an adequate temperature programme.

Gas chromatography-Mass Spectrometry (GC-MS)

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%).
