Het restaureren van middeleeuwse documenten in België in de loop van de 20ste eeuw. Nieuwe technieken - nefaste gevolgen

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

In the 20th century, a number of new techniques developed for the restoration / preservation of medieval parchment manuscripts using new synthetic substances. The aim was to protect and stabilize the text, but after several decades they were drastic side effects which severely damaged the original parchment material. In the early 20th century, for example, there was the new technique of Zaponizing parchment and archival documents. These methods were particularly hopeful as a method against the acidity of the inks and the degradation of parchment by microorganisms. The technique was developed around 1890 by the chemist dr. E. Schill in the Hygiënisch chemisch Laboratorium of the Prussian War Ministry. A second case study is the treatment of a large 15th century architectural design of the St. Pieters Church in Leuven, on a hot vacuum table in 1962, with a dramatic shrinkage of the parchment as result when the temperature was raised to 35°C. The lack of knowledge of parchment and collagen as a very specific material let to improper restoration treatments, and affecting the structure, physic stability and esthetic appearance fundamentally.
