GELLAN GUM AND AGAR COMPARED TO AQUEOUS IMMERSION FOR CLEANING PAPER

(Translated by Mónika Lökkös)

An important step in the treatment of paper-based documents is wet treatment, which removes contaminants and degradation products from the fibres that damage the pulp. In some cases, however, the writing or dyeing materials and adhesives on the substrate are water-sensitive, making wet treatment impossible. In such cases, wet cleaning and treatment with gels is a good alternative. A possible case study of this is the article in translation, which describes the treatment of an album of sketches by a French artist. The results of preliminary studies and tests carried out before the restoration process began, as well as references from the literature, provide important information for the restorer faced with similar problems. The article also describes the criteria for selecting the right gel for the treatment of the album, followed by the procedure carried out, its results and the experience gained. There are many types of gels and their use is becoming increasingly popular in restoration practice, as the right type can be selected for more sensitive materials, allowing the necessary wet treatments to be carried out. Cleaning procedures with gels have achieved very good results in removing water and adhesive stains, using solvent treatments gently under controlled conditions. The presentation of recent results in this field is very useful for the restoration profession.
