Cooperation with the Hanover University of Applied Sciences and Arts

Research Centre for Mass Conservation and Processing Systems for our written cultural heritage (FoMaSK)

At the Faculty of Process, Energy and Environmental Technology of the Hanover University of Applied Sciences and Arts the interdisciplinary research group on Mass Conservation and Processing Systems of Written Cultural Heritage, FoMaSK was set up, which has become one of the areas of specialisation at the interdepartmental research centre AUBIOS. Under the leadership of Professor Dr.-Ing. Ulrich Lüdersen the areas of expertise and professorships of process technology, thermo-chemical methods engineering, biotechnology, chemistry, materials engineering and production technology involved in mass conservation of archive materials have been brought together in a single research group. FoMaSK's task is to conduct research on and develop mass conservation systems and the related quality assurance of written cultural artefacts.

A specialised laboratory with its own technical equipment for the cleaning and deacidification of various materials and its own quality control lab, which in addition to research is equipped to carry out quality assurance and quality control in connection with deacidification, conservation, cleaning and ageing of archival materials has emerged from the pooling of laboratory activities in the individual faculties of the Hanover University of Applied Sciences and Arts. A large number of term papers and theses and the engagement of the scientists and professors demonstrate their high level of scientific expertise.

Areas of focus:

  • Deacidification, stabilisation, cleaning and decontamination of archival materials
  • Studies of ageing
  • Technique for handling archival materials
  • Development of gentle measurement techniques for quality assurance testing
  • Digitisation methods
  • Process assurance
  • Quality assurance and control

Cooperation between GSK and the research area FoMaSK led to the initiation of the research project “Deacidification and Consolidation of the Paper Cellulose Structures of Written Cultural Heritage Materials by Means of Dispersed Multiphase Systems” and enables basic research on the findings of which flow into further development of GSK technology. The first result was the optimisation of single-sheet conservation for especially fragile newspaper pages and the resulting development of the Newspaper CP process. A further milestone was the establishment of the world’s first technology for gentle mass deacidification and consolidation of bound materials and books. The book conservation process is not only capable of sustainably conserving bound materials gently and efficiently, but it can also stabilise, clean, and effectively decontaminate these mechanically in what is also a process never before used worldwide.
