Eulaliopsis binata is a wild herbaceous plant that grows more in the hilly areas south of the Yellow River in China. Paper manufacturers will make pure dried pulp boards and sell them locally. The process of barnyardgrass pulping is the same as that of wheat straw. It is through the process of crushing, beating, bleaching, drying and the like. Grass pulping only takes 2-3 days, and the pulping process is simple and intensive. The content of heterocells and impurities is inevitably affected by the paper.
Since the nature of the yarrow is relatively soft, it can be quickly dissolved by soaking in water after being made into a pulp sheet. After painting and paperboard manufacturers buy back the pulp board, they are soaked into a paste by the pulp board and beaten with a beater. It takes only 3 days to make the painting and calligraphy paper from the pulp board. That is to say, from the rush to the painting paper, the whole process is only about 5 days.
The ink repellency of calligraphy and painting paper is entirely dependent on its own solvency characteristics. Compared with rice paper, the ink painting performance of calligraphy and painting paper is irregular, uneven, and has no hierarchy. It is just infiltration. Beginners are often used to practice calligraphy, and practicing painting is not ideal. The most important point is that in terms of anti-aging and durability, it cannot be compared with the “ink and beauty†of rice paper. Its shelf life is only a few decades. If it is not properly kept, it will fade and infest in a shorter time.
So, how to identify rice paper and calligraphy paper? One is the naked eye method: pick up the paper, facing the light perspective, Xuan paper covered with cloud-like filaments, these filaments are the tannin fibers, but also found in the strands of rice straw. And there is no such thing on the calligraphy and painting paper made by the rush, and it is relatively pale. The second is the inking method. Four types of ink traces are traced on the same piece of paper to observe the effect of the ink on the paper. The rice paper can clearly show the pen marks and layers, while the calligraphy and painting paper is blurred at the intersection of the pen marks. Especially after the heavy adsorption and the thick ink, the paper may be broken due to the poor fiber.
The painting and calligraphy paper is just a kind of ordinary paper with the characteristics of ink painting. Since the 1980s, it has emerged with the development of the economy and the market. Its main producing areas are Fuyang, Zhejiang, Du'an, Guangxi, Jiajiang, Sichuan, Qian'an, Hebei, and Qixian, Anhui. At the beginning, the raw materials of the painting and calligraphy paper were alfalfa pulp, wood pulp, bamboo pulp, waste paper pulp, etc., and the quality was uneven. Gradually used as raw materials were the ryucas moss pulp produced in Hubei and Henan.
