| Abstract:Previous studies on characterizing ancient Chinese coated papers rely mainly on microscopic observations and/or elemental analysis of the paper’s surface, which are often subjective in interpreting the observations and analytical results. Exploration of new methodologies that produce more reliable results with clearer judging criteria is needed. The present research applied jointly Micro-Computed Tomography (micro-CT) and Raman spectroscopy to the samples of both ancient and modern handmade Chinese papers for the first time. As suggested by the results, micro-CT could distinguish between coated and uncoated papers as well as between single-side and double-side coated papers. Raman spectroscopy could characterize or identify the coating pigment (as well as other substances) in the coating layer. The new methodology established here was completely non-destructive and could produce scientifically conclusive results regarding the coating layer and coating pigment, which offered new insights into the manufacture of ancient Chinese coated papers. |
