Itwon a gold prize at the Panama Fair a century ago. Xuan paper was first made in Xuanzhou (Anhui Province today) during the Tang Dynasty (618-907). The paper gets its name from Xuancheng where the raw materials for making paper were bought and sold. There are two kinds of Xuan paper—raw Xuan and processed Xuan in different lengths. The first is good for calligraphy and flower and bird paintings and the latter is best for figure drawing.展开更多

Its remarkable performance and profound historical value are highly regarded by artists and the paper commands very high price in the commercial market. Ink penetrates and spreads optimally in the paper and the words exhibit clear edges with small fluctuations because of the desirable wettability and wicking. These characteristics make it stand out from three Xuan paper samples. The good wettahility, verified by contact angle measurements, is an essential prerequisite to strong wicking. Attenuated total reflectance Fourier-transform infrared spectroscopy is performed to determine the chemical structure of Qianlong Xuan paper and the relatively large hydrogen bonding ratio contributes to the hydrophilicity. The microstructure investigated by scanning electron microscopy and atomic force microscopy reveals wide fibers and a uniform fiber arrangement with good connectivity, dense network, as well as rough fiber surface. These unique properties endow Qianlong Xuan paper with strong wicking to improve the ink expression.展开更多
