Using various scientific detection methods such as optical microscopy （OM）, fiber dyeing analysis, field emission scanning electron microscopy-energy dispersive spectroscopy （FESEM-EDS）, micro X-ray diffraction （micro-XRD）, and attenuated total reflection Fourier transform infrared spectroscopy （ATR-FTIR）, this study conducted comprehensive analyses to the paper of the Ming handwritten edition Wen Yuan Ying Hua in LI Shengduo’s book collection. The results showed that the paper used in this book was muscovite filler paper made of paper mulberry bark, which indicated that it should be a type of “mica paper” from the Ming Dynasty.
Besides, its manufacturing process could be speculated to be made by adding mica to the pulp, which differed significantly from the ancient traditional handmade mica paper prepared by coating as recorded in literature, as well as modern handmade mica Xuan paper and machine-made mica paper.
