The combination of elemental, microstructural, and molecular characterization allowed for the identification of ancient gilding technologies and the main decay processes. Two different types of gilding were identified: one, original, employing a thin gold leaf and redecorations with a laminated structure of gold over tin foil. Degradation of the organic materials employed as binders and tin oxidation were the main decay processes affecting the gildings.
