Report on the Exhibition “Animal Glue and Conservation – To Keep ≪Jo-no-mai≫ -”

Gallery exhibition

 The Center for Conservation Science has been developing materials required for the restoration of cultural property. One of the items subject to our research is glue. Glue, an animal collagen hydrolysate, has been used as an adhesive since ancient times. According to the information found, the kinds of animals used for producing glue vary and different measures have been used to find better ways to manufacture it.  On the other hand, it has not been scientifically defined whether the raw materials and manufacturing methods have any effect on the properties of glue. In recent years, research on the raw materials of glue and its manufacturing methods has finally been carried out. Based on these results, the Restoration Materials Section has been conducting research studies on the characteristics of glue as a restoration material.
On the case of the restoration of a famous Japanese-style painting, “Jo-no-mai (Noh Dance Prelude,” designated as an Important Cultural Property, the suitable glue was selected based on the outcomes of the studies. It is notable that by using glue which keeps whiteness of shell chalk, restoration, which minimizes the possibility of changes in original works, was implemented.
 These outcomes were displayed in the Chinretsukan Gallery of The University Art Museum, Tokyo University of the Arts for the Exhibition “Animal Glue and Conservation – To Keep ≪Jo-no-mai≫ -.” The exhibition was co-organized with the Conservation Science Laboratory, Graduate School of Conservation, Tokyo University of the Arts from October 14th to 19th, 2018. In cooperation with Nikawa Labs as one of the organizers, the exhibition displayed the actual glue used for restoration, scientific data, and numerous images including enlarged ones taken during the restoration process. In addition, a visiting researcher, Kentaro UDAKA, delivered gallery talks. This exhibition provided a valuable opportunity for visitors to gain a broad understanding of the relations between research outcomes and the workplace for the restoration of cultural properties.
