点击翻译按钮获取中文摘要

In this project, we were able to manufacture glue using only water and animal skins such as oxhide in all processes from raw material processing to glue manufacturing. In these processes, we did not use any chemical or additive such as coal, antiseptic agent and hydrogen peroxide solution. We also developed equipment and manufacturing technology for the processes such as raw material processing, extraction and drying of glue. Establishment of the procurement channel for raw materials also allowed us to distribute quality products appropriate for specific purposes including, but not limited to, restoration material for cultural property, adhesive for Japanese painting and manufacturing of sumi ink, with indication of product information such as raw material and quality.
