X-ray Fluorescence Offers Clues to Cornell Library’s Medieval Manuscripts

X-ray fluorescence (XRF) can non-invasively find traces of chemical elements, offering clues about the origins of centuries-old paintings, manuscripts, ceramics, and stained glass. For example, researchers at the library at Saint Catherine’s Monastery, a 1,452-year-old institution at the foot of Mount Sinai, Egypt, use x-ray technology to discover once hidden text and discover lost characters from extinct languages.
