During this three-day workshop (of morning lectures and afternoon practical sessions), participants will be presented with a review of basic aqueous cleaning techniques / strategies for paper substrates. The notion of generally ‘isotonic’ bathing of papers that are wet-cleanable will be introduced together with pH and conductivity measurements on paper surfaces, and the construction of simple bathing systems that accommodate these factors.
Simple aqueous carrier or gel systems (agarose and xanthan gums) and the use of enzymes in aqueous paper conservation treatments will also be covered and participants will be encouraged to explore the BRENDA enzyme database online to better engineer their own enzyme preparations. More advanced macro- and micro-emulsions for blending solvent and water cleaning systems together for both ‘wet’ and ‘dry’ cleaning needs, including the cleaning of water sensitive media, and leather and parchment materials will be discussed.
The goal of this course is to better empower the participants to formulate tailored preparations for common surface cleaning problems (soil, staining, and adhesive removal) that require minimal aqueous interventions.
