Comparison of lightweight Japanese tissues for overall stabilization of documents damaged by iron gall ink corrosion and an alternative to silk screen frames

Abstract

<jats:title>Abstract</jats:title> <jats:p>Paper documents with severe iron gall ink corrosion are difficult to handle. While a defined treatment for the chemical stabilisation exists already, methods to improve the mechanical stabilisation have yet to be developed. The degradation of the selected objects was so advanced that the documents needed special attention concerning handling and mechanical re-enforcement. After a calciumphytate-calciumhydrogen treatment, documents were lined with light weight Japanese paper and gelatine. A workflow for treating severely degraded iron gall ink documents was developed. Since the removal of objects from the silk screen frames after the wet treatment proved to be too difficult, a PE-board was introduced as an alternative washing support. Most synthetic fleeces such as Hollytex or Paraprint adhere to its granulated surface by mechanical means. This makes PE-board a practical support during any wet treatment of paper-based objects.</jats:p>

Plastics in robots: a degradation study of a humanoid skin mask made of soft urethane elastomer

“…The gluing stripes consist of Japanese paper, which were tested with several adhesives. The ripped longfibred Japanese paper (100% Kozo fibres, 12 g/m 2 , Deffner & Johann GmbH), a material widely used in the conservation field [30][31][32], should allow a smoother transition between edges and provide sufficient strength due to the Kozo fibres length. The adhesives should be soluble in water to avoid the exposure of the PUR to harsh solvents and guarantee a long-term flexibility and elasticity [33]; therefore, cellulose-based adhesives were tested [34] [35,36], was also considered in order to investigate the effectiveness of a compatible product with the PUR mask.…”

Combining phytate treatment and nanocellulose stabilization for mitigating iron gall ink damage in historic papers

“…Chemical treatment, however, is only one aspect of a process to effectively preserve manuscripts damaged by ink corrosion. Ink corrosion is often accompanied by severe mechanical damage (cracks, fractures) which makes additional physical stabilization necessary [23,24]. Hence, local support of damaged paper areas with Japanese papers, adhesives or remoistening tissues is usually applied, depending on the degree of damage [25][26][27][28].…”

“…Hence, local support of damaged paper areas with Japanese papers, adhesives or remoistening tissues is usually applied, depending on the degree of damage [25][26][27][28]. In the case of severely impaired manuscripts, several authors suggested lining the documents with Japanese paper directly after aqueous or chemical treatment [18,23,24,29]. In the present study, we test whether stabilization with nanofibrillated cellulose-one type of nanocellulose-can be implemented directly into the phytate treatment sequence.…”
