ABSTRACT

This study focuses on the scientific analysis of Song-dynasty Song-dynasty paper (sutra paper). Using optical microscopy, fiber identification, Py-GC/MS, UPLC-QTOF MS, and visible–near infrared multispectral imaging, the paper was identified as kozo-based, dyed with huangbo (Phellodendron bark), sized with animal glue, and coated with beeswax. The results confirm the structure and composition typical of high-quality sutra paper from the Song period. Multispectral imaging further revealed traces of Buddhist texts, proving the reuse of ancient sutra fragments in Qing imperial production. This research provides new scientific evidence for the study of Song papermaking technology and offers valuable references for the conservation of ancient papers and imperial artworks.
