Manufacturing Techniques of Tussah Paper
The manufacturing history of tussah paper is as long as that of linen paper. The raw material for making the paper is the phloem fibers of the tree. The bark of the tree contains wood phloem fibers which are very suitable for papermaking.
On June 7, 2008, the paper was approved by the State Council to be included in the second batch of national intangible cultural heritage list.

Because of its long history and suitable for high-level painting and calligraphy, it has been paid special attention by literati. Sometimes the word "chu" becomes the symbol of paper. For example, Zhang Yi (1237-1368) wrote in his poem "Wood and Stone Pictures" for Zhao Mengfu, a contemporary Wuxing calligrapher and painter (1254-1322): "Wu Xing's brushwork is wonderful, and there are no people left behind. A piece of paper is a piece of paper. Xu Wei (1521-1593), a Ming Dynasty painter, said in"Painting Crane Fus": ink is like work, and life-long fun. Here the ink is paper ink, which means that if the ink and paper are made fine, it can be appreciated for a lifetime after being painted and calligraphed. Other scholars took it as their subject matter and personalized it into a funny biography.
Technological improvement in the Ming Dynasty was a major stage of Chinese handmade paper. The manufacture of tussah paper was particularly prominent. It was produced in almost all parts of the country. It was suitable for various purposes. Its output, quality and processing technology reached an unprecedented high level.
During this period, there were also detailed documentation about the manufacture of paper. Dazhi of Jiangxi Province, edited by Wang Zongmu (1523-1591) of the Ming Dynasty in 1556? Chu Shu Chapter is the earliest work in the world to discuss in detail the manufacture of Chu Paper.
Dazhi of Jiangxi Province mainly records the technology of making paper in Yushan County, Guangxinfu Prefecture of Jiangxi Province (now Shangrao area) during Hongwu Period. According to Mr. Pan Jixing's research, the technological process of this kind of paper is as follows: immersing the material in water for several days, bundling it into small handles, boiling it in clean water, cutting the inner bones, pulling the bark into silk, cutting the bark into small bundles with knives or axes, soaking it with lime pulp, and storing it for the rest of the month, soaking it with lime pulp. Cooking in the pot taking the material out of the pot, rinsing the water naturally for several days in the cloth bag with river water treading to limewater pestle spread on the ground or hillside in the sun and rain, until color white using treadle or pestle mortar to make fine adding boboiled grass wood ash water on the pestle material to bubble, half a month dry river water washing material re-boiling water into the pot again into the boiling water to boiling in the pot again._Exposure to sunlight_Hand handling of secondary materials and miscellaneous materials Quality rejection fine chopping with knife, until crushed into pieces washed in the inner bag mixing with water into the tank adding paper to the tank salvaging paper pressing water drying of the fire wall uncovering paper from the wall trimming and packing. This method includes four times of cooking, including two times of fresh water cooking and two times of alkaline solution cooking. After this treatment, the paper is white as jade, the fibers are even and fine, and the surface is smooth, but it takes a lot of time and labor. The rulers never care about the cost of paper.
In addition to Jiangxi Dazhi, Huizhou Zhi (1502), edited by Peng Ze of Ming Dynasty, and Tiangong Kaiwu, edited by Song Yingxing, also have some technical records on paper, but they are relatively simple and less formalities.
