Lipid residue analyses can be performed on the drilled powder from the fabric of a vessel, and any preserved charred remains adhering to the interior. Plant microfossil analysis can only be performed on the interior charred deposit. The protocols for sampling both are outlined in this resource.
Our understanding of the uses and values of plants in the past is limited in comparison to other foodstuffs, and this is especially true in prehistory. This is in large part because of the poor preservation of macroscopic plant remains, the limited scope for bimolecular techniques to detect all but oily and waxy plant products.

During cooking, molecules coming from the food will become trapped and preserved within the porosity of the vessel or in charred deposit. Lipids, a very stable molecular family, can be recovered by extraction and breakdown to analyse individual molecules. Read this resource to find out more.
This presentation describes the analysis of lipids (fats, oils, waxes) extracted from archaeological artefacts, focusing on prehistoric ceramic sherds from Japan and Korea. The film (available in English and Japanese) was recorded in BioArCh, the Department of Archaeology, University of York by members of the EPRG. English language
