The Buddhist scrolls from the Ficke collection had experienced pretty significant insect damage which greatly increased the risk of damage during handling. In order to stabilize the paper structure, Kate and I performed some basic paper mends using a remoistenable tissue. We had previously tested the inks to make sure that they were not water soluble, but we wanted to avoid exposing the scrolls to excessive moisture because tidelines easily formed and the sheets composing the scrolls were most likely adhered together using a starch-based paste.
We selected several types of Japanese tissue to prepare for the mending and began by first toning them with acrylic paint to better match the color of the scroll (Picture 1). Next, a 50/50 mixture of methylcellulose and paste was brushed over the surface, and the tissues were allowed to dry.
To mend the paper, the area of loss was traced on the tissue using a needle point (Picture 2). A protective, transparent piece of Mylar was placed between the scroll and the mending tissue while tracing. Now comes the “remoistenable” phase of the treatment. The paste and methyl cellulose mixture becomes reactivated in a 1:1 mixture of water and ethanol. The mend was placed on a piece of Plexiglas or cotton blotter and the ethanol/water mix was brushed over the tissue (Picture 3). A tweezer was used to place the mend onto the loss on the paper surface (Picture 4), and then a blotter and weight are placed on top to help the repair to dry flat (Picture 5). All of the repairs were applied to the back of the scrolls so as not to interfere with the manuscript, and Picture 6 shows what a large section of mends look like after drying.
