On October 13, Hainan Da Guan Agarwood Company made a breakthrough in the research and development of incense leather paper (honey incense paper). The paper is "extremely tough, does not rot in water, and does not grow insects and moths". It is an important paper for the conservation and restoration of ancient books and the reconstruction of national rare books. The pilot phase has been completed and a major breakthrough has been made from scientific research to industrialized production.

    Hainan Da Guan Agarwood Company incense leather paper (honey incense paper) is in the "Kaihua paper research laboratory Yang Yuliang academician workstation". It took more than two years for the team led by Huang Hongjian, the non-genetic inheritor of Kaihua paper, to be successful in practice. In this research and development, more than 120 pieces of incense bark paper (honey incense paper) were produced, which is a step further than last year's small trial.

    The paper is a traditional hand-made paper-making technique, which has been lost for hundreds of years and is not visible in kind. Only a glimpse of its noble and magical appearance can be found in the canon. Jin JIHAN's "Southern Herb and Wood" contains: "Honey incense paper, made from the bark and leaves of the honey incense tree. Slightly brown, with a caviar-like pattern, extremely fragrant and strong and tough, water-soaked, not ulcerated".

    The paper of incense bark (honey incense paper) has a certain fragrance because it is made of incense bark. However, this statement is inconsistent with common sense and the actual paper produced in this case. One is that incense bark is not fragrant；Secondly, even if the incense skin has a little clear fragrance, it will disappear during the papermaking process. Experts who know how to make paper by hand know the reason for this. If the incense vellum does have a fragrance, it should be added later. For example, at the end of the process or after the paper is formed, materials containing incense ingredients are added, and the fragrance is naturally present.

    The success of this research and development of Hainan Da Guan Agarwood Company agarwood leather paper (honey incense paper),will add a bright luster to the recovery of our traditional handmade paper skills. New materials for solving the problem of paper for restoration and conservation of ancient books in China. At the same time help Hainan incense industry further development, promote the research and development of incense products to achieve new breakthroughs.
