Paper and paste are important materials for painting and calligraphy mounting. Their properties affect the overall beauty and longevity of mounting parts. Japan has inherited the traditional mounting style of China, but has also developed its own unique mounting materials—Japanese paper and ancient paste. Paper and paste with different properties are used in different stages of mounting, which reflects the inheritance and innovation spirit of traditional mounting culture. Successful experience with the combined use of ancient paste and Japanese paper could provide some reference relevant to the inheritance and innovation of traditional mounting techniques for Chinese paintings and calligraphy.
