The article delves into the analysis of Wide Horizontal Rim (WHR) vessels from the Bronze Age in the Northwest Iberian Peninsula, focusing on the organic residue found on these pottery artefacts. The study aims to uncover the composition and significance of the dark residues observed on the vessel’s inner wall, indicating past exposure to fire.
By utilising Gas Chromatography-Mass Spectrometry (GC-MS) on powdered samples, the researchers identified a complex mixture of degraded ruminant fats and vegetable oil residues, suggesting the vessel’s use in containing a mixture that was subjected to heat. The presence of cholesterol and absence of squalene in the residues pointed towards animal fat residues, with a notable contribution of animal fats indicated by the palmitic to stearic acid ratio.
The findings not only provide insights into the functional use of WHR vessels, potentially as cooking or heating vessels, but also shed light on the cultural practices and technological capabilities of Bronze Age communities in the region. The study contributes to the broader understanding of WHR vessels’ social and ideological functions within the context of ancient societies, emphasising their role in daily life activities and rituals.
Furthermore, the research highlights the importance of organic residue analysis in archaeological studies, showcasing how scientific techniques can unravel the past uses and cultural significance of archaeological artefacts like WHR vessels. Overall, the study enriches our knowledge of Bronze Age material culture and the intricate relationships between pottery artefacts, human practices, and societal beliefs in the Northwest Iberian Peninsula.
