Ceramic vessel 177-1. Sanctuary of Piedra del Águila (Orcera, Jaén, Spain)

Ceramic fragment 177-1. Iberian sanctuary of Piedra del Águila (Orcera, Jaén, Spain). Wheelmade ceramic, oxidising firing. It has no decoration. The analysis of lipid contents was carried out using GC-MS and GC-C-IRMS, obtaining a lipid profile characteristic of a mixture of non ruminant and ruminant animal fat. This conclusion is based on the identification of di and triacylglycerols (PP; PS; SS; PMP; PPdP?; PPP; PPO; PPMa?; PSP; SPO; SPS; SSS), and ∆13C %3D 0.23.

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%)
