A medium‐throughput approach for improved taxonomic identification of lipids preserved in ancient pottery
Organic residue analysis (ORA) is a valuable tool for the study of ancient diets, but conventional methods remain limited in terms of taxonomic identification or to resolve mixtures. Here, we propose a method to further explore a class of compounds—triacylglycerols (TAGs)—using high‐resolution mass spectrometry to overcome these limitations in an attempt to better characterise culinary practices. Over 70 medieval Sicilian pots and a wide range of…
Unravelling ceramic content and organic coatings in Senegalese ethnographic pottery vessels
From pottery use-alteration to food habits
A use-alteration study uncovered the food habits of a 20th century village in Senegal. • The large size of the sample enabled a multivariate approach on use-alterations. • Methodological keys are detailed to distinguish use-alterations from post-depositional alterations. • The study brought information on the way of use, contents and types of contact on pots. • Repetition of use-alteration on morphotypes enabled the identification of pottery func…
The ARchaeological Organic residues Literature Database (Arold)
The first attempts to identify amorphous organic substances in archaeology date to the end of the 19th century and the beginning of the 20th century. The 1960s saw the development of infrared spectrometry, and then separative and mass spectrometry analyses were implemented in the 1980s. But it is only since the 1990s that extended and systematic research programmes were devoted to these substances. The number of publications has not stopped growi…
Relationships Between Lipid Profiles and Use of Ethnographic Pottery
There’s more to a vessel than meets the eye
Despite growing evidence to the contrary, wine remains the assumed content of many types of ancient pottery. Vessels from the Kyrenia and Mazotos shipwrecks, and Yeronisos island presumed to have contained wine were subjected to three different extraction protocols to test the assumption that these vessels were used to import and serve wine. Chemical extracts reveal grapevine products but also other fruit juice, beeswax and plant oil, sometimes m…
Investigating the formation and diagnostic value of ω ‐( o ‐alkylphenyl)alkanoic acids in ancient pottery
Long‐chain ω ‐( o‐ alkylphenyl)alkanoic acids (APAAs) derived from the heating of unsaturated fatty acids have been widely used for the identification of aquatic products in archaeological ceramic vessels. To date, little attention has been paid to the diagnostic potential of shorter chain ( 20 ) APAAs, despite their frequent occurrence. Here, a range of laboratory and field experiments and analyses of archaeological samples were undertaken to in…
Is it possible to identify ancient wine production using biomolecular approaches
Chemical analysis of archaeological artefacts is used with increasing regularity to understand how wine was produced, traded, and consumed in the past and to shed light on its antiquity. Based both on an extensive review of the published literature and on new analyses, here we critically evaluate the diverse range of methodological approaches that have been used for wine identification. Overall, we conclude that currently none of the proposed che…
A Neolithic without dairy? Chemical evidence from the content of ceramics from the Pendimoun rock-shelter (Castellar, France, 5750–5150 BCE)
A pottery biography
Over the past thirty years, the study of the exploitation of natural substances by ancient societies has been a major focus of organic residue analysis in ceramics. However, the mechanisms controlling the absorption and preservation of organic matter within the walls of pottery at all stages of a vessel’s lifecycle are still very poorly understood. Organic and mineral composition of the paste, surface treatments, porosity, environmental condition…
Leftovers
Lipids preserved within the walls of ancient pottery vessels are routinely analysed to reveal their original contents. The provenience of aquatic lipids in pottery is generally connected to vessel function (e.g., for cooking or storing fish, shellfish and aquatic mammals). However, ethnographic reports from early historic Alaska mention the use of aquatic oils for waterproofing low‐fired pottery. Results of lipid residue studies on Alaskan potter…
The Missing Step of Pottery chaîne opératoire
Post-firing treatments, produced by the interaction of an organic material with the hot surface of a ceramic, are frequently described in ethnographic literature, but have rarely been identified in archaeological ceramic assemblages. In order to address this question, this paper describes a methodology that combines macro- and microscopic observation and molecular analysis. The study of experimental ceramic vessels provided diagnostic tools to id…
Influence of porosity on lipid preservation in the wall of archaeological pottery
Porosity of archaeological pottery is a key parameter used to assess its ability to trap lipids during the use of the pot and to preserve them over time. Mercury intrusion porosimetry and gas chromatography were used to study the distribution of porosity and the preservation of lipids in different chrono‐cultural contexts. The data obtained show that the porosity pattern, related to the raw materials and the savoir‐faire of the potters, influence…
Domestic activities and pottery use in the Iron Age Corsican settlement of Cuciurpula revealed by organic residue analysis
The role of pottery in Middle Neolithic societies of western Mediterranean (Sardinia, Italy, 4500-4000 cal BC) revealed through an integrated morphometric, use-wear, biomolecular and isotopic approach
Substances naturelles liées aux céramiques archéologiques
Grâce aux recherches en archéologie biomoléculaire, la connaissance des substances naturelles conservées sous forme de résidus organiques amorphes a fait des progrès considérables ces dernières années, passant d’observations et analyses ponctuelles à des recherches de fond basées sur l’étude de séries archéologiques conséquentes. Molécules parmi les plus stables face aux divers mécanismes de dégradation, les lipides ont été l’objet de la majorité…
