Residues on unglazed Roman pottery: extraction of organic spectral signatures via ATR-FTIR and machine learning.

ABSTRACT: The study of organic residues on archaeological objects offers invaluable insights into past human behaviours, including diet, trade, storage, and ritual practices. Here, we present an innovative analytical approach that combines attenuated total reflectance Fourier transform infra-red spectroscopy (ATR-FTIR) with machine learning techniques to extract spectral signatures for identifying organic residues within complex inorganic matrix, primarily depositional materials in archaeological contexts. The methodology was applied to the study of six unglazed ceramic artefacts coming from a sealed context of a taberna looking onto the Forum area of the archaeological site of Peltuinum Roman city, central Italy. The probable commercial nature of the taberna and the porous, unglazed pottery support
