The hand scroll is the earliest traditional Chinese mounting form. Developed from the Jin to the Qing Dynasties, it is seen as having three classic styles:butted-edge, wrapped-edge and folded-edge hand scrolls. For the last style, there are two kinds of jointing techniques:jointing of whole silk and assembling of small pieces of silk. For most of the hand scrolls from the Qing Dynasty to the Republic of China that have been handed down to us, the technique of assembling of small pieces of silk, which saves more silk materials, was adopted. However, this process is complicated and difficult, resulting in its fading away and even the danger of being lost in the contemporary era. Using the restoration and re-mounting of a Ming Dynasty hand scroll in the Shanghai Museum collection as an example, this paper describes research on its original mounting materials, color matching and jointing technique, as well as the process of mounting for this folded-edge hand scroll according to its original size. This work studies, conserves and passes on the excellent traditional skills of our ancestors.
