A Study on Restoration of Mounting the Four-fold Screen of the Sun, Moon and Five Peaks in Injeongjeon, Changdeokgung Palace: Focusing on Adhesion and Stabilization Treatment for Gold Leaf

Abstract

The Four-fold Screen of the Sun, Moon and Five Peaks in Injeongjeon, Changdeokgung Palace is a representative royal decorative painting made to divide the space inside the palace or to decorate and direct a specific space in the Joseon Dynasty. This painting has been repaired several times, but severely damaged by external ultraviolet rays and pollution. To study the Four-fold Screen of the Sun, Moon and Five Peaks from the Joseon Dynasty, records and similar cultural heritages were researched. Conservation treatment was performed based on the research results. This study sought to determine the appropriate concentration of adhesive and gold leaf stabilization treatment. The study a ssumed tha t the silk wa s mounted on a folding screen to ma ke a new decora tive silk a nd a tta ch gold leaf during the mounting process. Properties of the adhesives were compared by observing and measuring viscosity and adhesion, and color values, and gloss of the specimens before and after stabilization treatment. The most suitable adhesive for gold leaf adhesion was rabbit skin glue 5% and funori 4% in a 5:1(v/v) ratio. In addition, when the gold leaf surface was coated with 1% rabbit skin glue, the yellow color of the gold leaf was further emphasized. This stabilization treatment was effective in preventing peeling of the gold leaf surface.
