TL;DR: Atomic absorption spectrometry is used to analyse both major elements and trace elements in archaeological objects as discussed by the authors, and schemes of analysis are described for ancient metals and silicate-based materials, based on samples of material drilled or abraded from the object.

TL;DR: In this paper, the identification of glycerides in ancient amphora wall fragments by gas chromatography with mass spectrometry is presented as a means of determining if the amphorae had contained olive oil.
