Scientists develop handheld XRF scanner method for ancient scroll deciphering

Scientists working on the preservation of ancient manuscripts have reported that a handheld X‑ray fluorescence (XRF) scanner can quickly identify the most promising scrolls for detailed study. The portable device measures the elemental composition of the parchment and ink, allowing researchers to detect variations in pigments and binding materials that signal different periods or origins. By screening dozens of fragile scrolls in a matter of minutes, the technique saves time and reduces the risk of damaging the artifacts during more invasive analyses.

The method was first tested on a collection of 1,500-year‑old scrolls housed in a regional museum, where the scanner successfully distinguished those containing rare pigments such as lapis lazuli from those with more common lead‑based inks. The data generated by the handheld device are then cross‑referenced with historical records and radiocarbon dating results, giving scholars a clearer picture of the scrolls’ provenance and historical context. Experts say the technology could be especially valuable in remote or resource‑constrained settings, where access to full laboratory equipment is limited.

While the handheld XRF scanner does not replace traditional laboratory techniques, it provides a rapid, non‑destructive first pass that prioritizes specimens for deeper investigation. The approach is expected to accelerate the cataloguing of vast collections of ancient texts and may become a standard preliminary step in the conservation of cultural heritage worldwide.
