No adhesive is employed. An eraser can be used on the support paper but not on the delicate thin India paper. Careful testing will indicate whether a light application of cleaning powder can be used for cleaning purposes. A 1981 research report prepared by the Analytical Research Service of the National Museums of Canada indicates that a block eraser works best. The study further determined that Pink Pearl, Opaline, Kneaded Rubber, and Magic-Rub erasers left detectable amounts of eraser material on the paper.
Photomicrographs show that the complete removal of eraser particles by brushing is unsuccessful.
The Magic-Rub eraser was found to be the most suitable for use in cleaning paper. Return to Preceding Section 7. Return to Table of Contents in Main Home Page.
