Mapping Materials and Dyes on Historic Tapestries Using Hyperspectral Imaging

Hyperspectral imaging has emerged as a promising analytical method of artwork due to its potential in combining non-invasive capabilities and allowing the survey entire (or large area the) surface an artwork, which is highly significant application for historic tapestries. This project deployed high-resolution ClydeHSI Art Scanner, was used with both push-broom visible very-near infrared (VNIR; 400–1000 nm) near (NIR; 900–1700 hyperspectral cameras. Initial testing focused on characterisation mapping different materials tapestries (wool, silk, metal threads). To facilitate dye characterisation, collection wool silk samples dyed recipes based medieval practices used. The measured using system data collected formed external reference library including type natural dyes mordants during their production. outcomes on-site deployment this instrumentation analysis 16th century display at Hampton Court Palace will be discussed.
