Scientists unlock secrets of ancient Egyptian materials with proteomics

Researchers have utilized mass spectrometry-based proteomics to analyze the composition of ancient Egyptian artifacts without damaging them. By studying glues and adhesives, the team identified a variety of organic materials, including animal collagens, egg proteins, and plant-based proteins derived from sesame and the drumstick tree. This non-destructive approach provides critical insights into the materials and techniques used by ancient Egyptian artisans, who employed a wide range of pigments such as hematite, orpiment, and the iconic Egyptian blue. The study, published in Science Advances, highlights how modern analytical chemistry can reveal historical manufacturing secrets that were previously inaccessible due to the fragility of the artifacts. These findings not only enhance our understanding of ancient painting styles and conservation needs but also demonstrate the growing role of advanced proteomics in archaeological research, allowing for a deeper exploration of historical material culture.
