The effectiveness of several combinations of fungicides in preventing the fungal deterioration of the silk artifact was tested and Dichlorophen was selected. The cleaning process was carried out with low powered vacuum suction, a soft brush and soft rubber. To restore the folding screen, the paper conservation based method was used. Therefore the remounting process was done using self-adhesive Japanese tissue paper to attach the support to the silk in order to avoid stitching through the painted surface. Consolidation was not deemed necessary because the paint surface was not actively flaking. Since the treatment method applied in this study could successfully conserve and restore the artifact with minimal destructive impact, it is worth replicating in similar conservation projects.

Description of the folding screen This study examined a Chinese folding screen from the late 19th century located in the Palace-Museum of Golestan. The screen has different designs and orna- ments on both sides of a silk background. Metal embroidery on a background of dark silk is visible on one side of the screen. A painting on non-dyed silk is visible on other side of the screen. In 1306 A.H (1889 A. D.)
