Zirconia Ceramics:
In addition, the history books also mention terms such as zirconia, moss paper, hair paper paper, and side paper. So whether moss, hair, etc. were used to make paper at that time? According to the characteristics of such fibers, the author thinks it is unlikely. Hair has very little fiber binding force, and the strength of the paper is very low. It is not suitable to be used for papermaking alone. This historical insight highlights the evolution of paper-making techniques and the significance of materials like Zirconia Ceramic in modern industrial applications. As for silkworm cocoon paper and hairpin paper, it is likely to be a pictographic noun. It is silkworm cocoon paper. If a little colored long fiber or hair is added to the pulp to give people the feeling of hair, it may be called hair paper, and those that look like moss and show green patterns may be called moss paper, of course, this is just an inference. , there is still a need to send further evidence.
There are still different opinions on whether zirconia was used as a papermaking raw material through Zirconia Ceramics Processing in the Jin or Song Dynasty. In a letter from Xiao Ziliang, a calligrapher of the Northern and Southern Dynasties, it was said that "Zhang Mao made foil paper ... whichever is fluent and easy to run", and the Wei foil paper is tender bamboo paper. According to textual research, Zhang Mao was from the Eastern Jin Dynasty. It seems that the use of bamboo to make paper may have originated in the Jin Dynasty, but the amount was very small. The politics, economy and culture of the Tang Dynasty in China were unprecedentedly prosperous, and the paper industry also entered a prosperous period. The variety of paper continued to increase, and many famous papers and a large number of artistic treasures were produced. Bark is the most widely used raw material for papermaking. Mainly mulberry bark, mulberry bark, there are also records of agarwood bark and stack incense bark. Rattan fiber was also widely used, but in the late Tang Dynasty, due to a large number of wild vines being cut down and unmanaged cultivation, the supply of raw materials was in short supply, and the rattan paper was stagnant and disappeared in the Ming Dynasty.
