Studies on the Washing of Paper: Part 2: A Comparison of Different Washing Techniques Used on an Artificially Discoloured, Sized Paper.

The article makes a comparison of different washing techniques used on an artificially discolored, sized paper. The beneficial effects of increased temperature on washing were studied along with several other variables related to wetting of the paper. It was established that the Arches paper was (compared with filter paper) relatively difficult to wet and, when immersed in water, took several hours to achieve the maximum cleaning available by the immersion process. The experiments described in this article, study the relative efficiency of seven aqueous washing techniques used in paper conservation at the British Museum.
