The article reports on the ink corrosion on handwritten documents at the Marburg University. The documents at the university were stored in barrier papers and were partially micro-filmed. The plan to digitalize jurist Carl Friedrich von Savigny's estate offered the first opportunity to display a spectrum of ink corrosion damage symptoms and to take conservation measures.

The rate of wetting and washing of paper was been studied in this article. The papers studied were an Arches artists' paper and a Whatman filter paper. The papers were used as supplied and as artificially discoloured by soaking them in a concentrated aqueous extract of old, discoloured paper. The wetting of the Arches paper was much slower than that of the filter paper; a surfactant accelerated the wetting of the Arches paper but had little effect on the filter paper. For both discoloured papers, the rate of washing was accelerated by the presence of surfactant. The rate of wetting and of washing was increased as the temperature increased. A period of storage at zero degree, relative humidity increased the extent of washing compared with paper previously humidified.

Focuses on an experiment to study the impact of aqueous treatment on the strength properties of Whatman filter paper. Information on folding endurance and tensile absorption of the paper; Explanations for the decrease in tensile strength of the paper after aqueous treatment; Discussion on long-term implications of decrease in tensile strength on the basis of different strength decrease scenario.
