Abstract
Highlights • Focused study aiming at technological parameters of corroded Mediaeval Zwischgold.
• Gold layer in a nanoscale thickness range of 20–50 nm, with the peak at 30 nm. Full foil thickness (50–260 nm) obtained from EDX derived Ag/Au weight ratio.
• Ultra-high-resolution SEM measurements, supported by STEM and RBS.
• Scientific evidence for paleness of Zwischgold A special gilding material called Zwischgold has been frequently observed in medieval gilded artefacts. As a bilayer metal leaf made from gold
