QUAC Insik (1919-1988) moved to Japan in 1937, graduated from the Japan Art School in 1941, and remained in Tokyo to work as a writer. In the late 1960s, he was an important writer when discussing the unicolorization of Japan and Korea in the 1970s by using natural materials and industrial materials in his works, and he explored materials even before the full-scale rise of the logic of things in Japan. He was interested not only in the peculiar material of glass, but also in the problems of surface and action by adding action to the surface, as well as in physical properties.
This work was exhibited at the Tokyo exhibition in 1984 and the National Museum of Modern and Contemporary Art in 1985 while the artist was still alive, and the key point of this work is the accidental shape of a crack in a representative large piece of glass.
The process of showing materiality by scratching and healing by re-stitching materials is one of the methods of modern art, and it can be said that it is an important task to show the artist's experience of experiencing the pain of the era of division between the two Koreas.
