Preliminary Research 1) size Unit: 尺(cm) 2) Damage (1) Damage type a. Creases The overall surface of the painting showed graces of horizontal creases that often appeared in hanging scrolls. Folded side view Folded front view Creases side view Creases front view b. Holes c. Top rod and rings The top rod faces reverse direction of general rods. Also, two rings were fixed on the front side of the top rod instead of the upper side. hole top rod hole ring d. Detached mounting Some parts of mounting paper were detached from the back sheets. Also, gaps were found between mounting paper and painting. In addition, some parts of layers were taken off at the back side of the scroll. detached gaps gaps taken off e.

Conservation Process 1) Preliminary research (1) Size, depth, and damages were recorded with photo evidence. (2) Forms of pigment surfaces were examined by magnifying the analyzed areas by a video microscope (IMS-M-345, Sometech Vision) (3) A portable X-ray Fluorescence Analyzer(Oxford Z-MET 5100) was used to identify the qualitative and quantitative composition of the pigments. 2) Dry cleaning The surface was cleaned by Dry sponge eraser. dry cleaning comparison of Dry sponge eraser 3) DismantlingDismantlingDismantlingDismantling Dismantling rings Dismantled rings Dismantling top rods Dismantled top rod Dismantling bottom rod Dismantling bottom rod 4) Wet cleaning The painting was cleaned by spraying of filtered fresh water wet cleaning Contaminants absorbed onto the cleaning paper 5) Removing the backing paper (1) Sewn threads were removed prior to removing backing papers (2) The patterned papers decorating along the edges of the scroll were pasted on the top of the mounting, even on the links of mounting papers. Thus, the backing papers were removed without separating mounting and painting. Removing thread Removing thread Removing backing paper Drying removed backing paper Strips on top of mounted paper Removing backing paper 6) Infilling the losses Infilling the losses with dyed Hanji(Korean Mulberry paper) Loss area Pasting Infilling After infilling 7) Adding the paper band Gluing mulberry paper strips to prevent bending. 8) Lining gluing paper band mounting lining painting lining lining lining 9) Drying After lining, painting was completely dried on the drying board. 10) Gluing decorated papers Before gluing paper Gluing Pasting After gluing paper 11) Color matching (1) Infilling papers were painted with same color of mounting papers. Before color matching Color matching After color matching 12) Storage 3.
