Spectral Imaging of Ink Behind Glass: A Preliminary Investigation of the Colorimetric Shift

Transparent glass frames are often used to exhibit, handle, and store ancient manuscripts (folia or fragments) across museums, libraries, collections. Once the carefully sealed (glazed), process of re-opening frame for analysis glazed manuscript is not always desirable, given their fragile state preservation. Therefore, microimaging with IR UV light sources above a frequently method preliminary (qualitative) classification inks applied on manuscripts. Building this well-established methodology, study explores potential spectral imaging technology quantitative The present research focuses colorimetric iron-gall carbon black papyrus substrate, aiming effect acquired images. obtained results show that can be inks, hence minimizing need open further analysis.
