Key Points

The aim is to accurately identify protein adhesive sources in polychrome cultural heritage using advanced analytical techniques.
Utilized gel sampling to extract protein adhesives from artifacts.
Employed ATR-FTIR spectroscopy for initial analysis.
Integrated machine learning algorithms for enhanced data interpretation.
Successfully identified multiple protein sources in various polychrome relics.
Demonstrated improved cross-species discrimination compared to conventional methods.
Showed potential for increasing the accuracy of conservation efforts.

Implication

Integrated analysis identifies protein adhesives in polychrome cultural relics, suggesting improved conservation techniques.

Abstract

Accurate identification of protein adhesive sources in polychrome relics is critical for their conservation. Conventional infrared spectroscopy faces limitations in cross-species discrimination of such adhesives. To address this, we developed...
