Residue analysis

Also called: organic residue analysis

Chemical identification of traces of food, drink, oils, resins or drugs absorbed into or left on the inside of ancient vessels.

Fats, waxes, resins and other organic substances soak into unglazed pottery and can survive for thousands of years. Extracted and analysed, usually by chromatography and mass spectrometry, they can show what a vessel held or how it was used. Results depend on preservation and contamination, and one positive result for one vessel says little about its whole class.

The best-known Cypriot debate concerns the Base Ring juglets whose shape resembles an upturned opium-poppy head. The claim that they carried opium has been tested repeatedly, with uneven and disputed results (Medicine and Healing). Many questions about food and drink, such as when wine was first made on the island, still await residue analysis.
