Proteomics Reveals New Details on Ancient Egyptian Adhesives and Binders

New Discoveries in Ancient Egyptian Materials

Scientists have applied mass spectrometry-based proteomics to analyze the composition of glues and adhesives found in a range of ancient Egyptian artifacts. This method allowed for the identification of specific proteins within these materials, providing detailed insights into their origins and manufacturing.

The study, published in Science Advances, revealed the presence of plant proteins derived from sesame and drumstick tree (moringa) cereals. These findings were alongside more commonly expected animal-based components such as collagens and egg proteins, expanding the known palette of materials used by ancient Egyptians.

Advancements in Non-Destructive Analysis

Analyzing the precise composition of ancient materials without damaging valuable artifacts has historically been a challenge. The development of advanced, non-destructive techniques, such as the proteomics approach used in this study, is crucial for unlocking these secrets.

These analytical methods contribute significantly to conservation efforts by providing a deeper understanding of the materials that need to be preserved and how they were originally created.

Context of Ancient Egyptian Craftsmanship

The ancient Egyptians were known for their formalized painting styles and sophisticated material use. Previous research has focused on identifying pigments and painting techniques, with common pigments including hematite, realgar, goethite, orpiment, Egyptian blue, Egyptian green, carbon-based black, and various white minerals.

Other non-destructive techniques, such as X-ray fluorescence imaging (Macro-XRF and MA-XRF), have also been employed to study ancient artifacts, including funerary portraits and tomb paintings, to determine elemental markers and remnants of color.
