Conservation and Restoration of Western Paper

In this instance, terylene, a dense syntheticpolyester fabric, was pasted to the surfaceof a light table. Next, two layers of ShikaJapanese paper were adhered to the terylenewith thin wheat starch paste applied with aspray bottle. While the lining layers dried,the map fragments were lightly humidifiedface down on Mylar with water mist torelax them before manipulating them intoproper position. Once aligned, the versosurface of the map and the lining weresprayed with dilute wheat starch paste. Themap was transported by the Mylar support,positioned on the lining and brushedthrough the Mylar to make smooth contact.After the Mylar was gently peeled awayand the map had air-dried, the terylene waslifted from the table and the adhered mapwas placed face down. The fabric was slowlypeeled away and the exposed verso of thelining paper was lightly sanded to removethe dried wheat starch paste. The liningpaper was trimmed, leaving a margin atthe perimeter to protect the damaged mapedges (Photos 5a-e; Photo 6).The Plan of the Water Communicationfrom Kingston to the Grand River is executedon 12 adjoined sheets of a thin translucentrag paper with an 1814 watermark ( JohnHayes) (Photo 7). Heavily soiled creasesand rodent damage became evident whenthe map was unfolded after humidification.The overall measurements were a meter wideby almost 2.5 meters long. The paper washighly susceptible to dimensional changesand the areas of loss were extensive. Thelocation and overlapping configurationfor each sheet were carefully documented,and the sheets were then separated bylocally applying water to the overlaps. Theindividual sheets could thus be repairedmore easily.After locally repairing tears on each sheetwith Kizukishi paper and wheat starch paste,the conservator chose to place the mapcomponents directly onto a prepared liningof two long adjoined sheets of Inoue Hainikozo paper using the terylene method justdescribed. Because of large size of lossesand dimensional instability of the paper,each component was thoroughly wettedout and re-aligned face-down on Mylarto prepare for transfer to the lining. Themap was transferred one half at a time,Photo 6 A Plan of the Province of New Brunswick, aftertreatmentPhoto 7 A Plan of the Water Communication from Kingstonto the Grand River, 1816, 98.5 x 235.0 cm, JosuaJebb, Library and Archives Canada, MIKAN4518120.
