Abstract A batch of paper manuscripts of the Tang Dynasty unearthed from the Western Regions represents one of the most important special collections at the Museum of Renmin University of China. These paper manuscripts are a unique source for studying history, religion, paleography, and culture. Due to their age and the detrimental storage environment, most manuscripts were severely damaged and incomplete and needed conservation treatment. One of these manuscripts dated to the 5th year of the Zhenyuan period (789 C.E.) was distorted and it was not possible to identify its content; it also posed serious challenges for handling. This paper proposes method for preserving this manuscript. Soiling was removed using dry-cleaning methods, followed by unfolding the folds with tweezers, mending losses and lining. After conservation measures, the surface of the manuscript was flat, and the handwriting was recognizable. For long-term storage and utilization, the manuscript was encapsulated in paper and stored in a self-made paper folder. This paper aims to contribute to research on a safe and reliable method for preserving severely damaged and distorted manuscripts.

Abstract A small framed display panel holds a selection of paper and media common in works on paper plus a set of Blue Wool Standards. The selection of materials and design of the panel including two types of glazing are presented, and the purpose of the panel as a tool for explaining the effects of light on materials is discussed. At the centre of the panel are watercolour samples prepared using primary colours in mixed washes that illustrate hue shift resulting from selective fading of one colourant.

Abstract Clay minerals possess several properties such as ion exchange capability, alkaline pH, adsorptive, swelling, and plastic behaviour, most of which are governed by their interactions with water. They have the capacity to interact with soluble molecules, which is particularly interesting for art conservation treatments. For all these reasons clays deserve to be considered for green and sustainable paper conservation interventions. In this work two phyllosilicates with different properties, namely montmorillonite and sepiolite, were investigated for the removal of tidelines on artificially aged paper samples. Water exchange, cleaning efficiency, and pH were evaluated comparing the clays to gellan gum, a benchmark cleaning hydrogel. A pouch made with regenerated cellulose was used to avoid direct contact of the minerals with the paper. The water sorption capacity of the clays combined with the specific permeability of the cellulosic membrane allowed for a homogeneous and easy to control cleaning. The formation of new tidelines, an inherent risk to any local conservation treatment of paper, was avoided. As an example, sepiolite was used for the local cleaning of a paper-based artwork’s multiple tidelines.

Abstract This article gives an overview over the development of gouache painting – from Flemish Waterverfschilderij, Lenten cloths (tüchlein paintings), miniature paintings, and landscape gouache in “heroic” and “rustic” styles to the landscape veduta of Alpine sceneries. The – often confusing – usage of the term gouache will be discussed and traced back in history, leading to a clear definition of our present-day conception. The findings are based on the study of art technological sources as well as observations of gouache paintings from a variety of different artists including Hans Bol, Marco Ricci, James Stuart, and Johann Ludwig Aberli. The author’s own experiences with gouache painting will also feed into the portrayal of a technique which in the past has often been disparaged and is underrepresented in the art technological research.

Abstract This study aimed to evaluate cellulose nanofibers and their effects on starch and gelatine as the most common surface sizing substances used in historical paper documents. In this study, cellulose nanofibers with a concentration of 1% by weight were prepared as a suspension with ethanol and used for the treatment of unsized samples and samples containing starch and gelatine sizing. The results showed that the application of cellulose nanofiber treatment increased the pH of unsized samples and samples containing starch sizing. After aging, there was a slight decrease in the pH of the samples. Cellulose nanofiber treatment increased the tensile strength of the samples. After accelerated aging, the tensile strength of samples containing starch and gelatine sizing and treated samples increased compared to untreated samples. Samples containing gelatine sizing and samples containing treated starch sizing showed the least amount of colour changes (∆E), respectively, and had the best colorimetry results. The results of the contact angle test of the samples before and after aging showed that cellulose nanofiber treatment did not increase the resistance of the paper to wetting and did not prevent the paper surface from getting wet.

Abstract The present study examined the preservation practices for information resources in seven public university libraries in Tanzania. Convenient and purposive sampling techniques were used to recruit library staff and library directors respectively to participate in the study. Data were collected through questionnaires and semi-structured interviews. The quantitative data obtained from the questionnaires were analysed using the Statistical Product and Service Solution (version 20) software while the qualitative data from the interviews were analysed using the thematic data analysis method. Regarding the effective preservation approaches for information resources, the study established that binding, digitization, migration, and emergency preparedness plans were highly cited. The following were the recommended preservation approaches for adoption in public university libraries: digitization, refreshing, proper shelving, and cleanliness of all library areas, migration, technology preservation, and binding. From the findings, it was concluded that public university libraries have a variety of preservation approaches for both print and digital information resources. The study recommends that policymakers and the Ministry of Education, Science, and Technology should train librarians in skills that they can apply in preserving information resources using modern technologies.

Abstract There have been many treatises left behind by Persian master calligraphers detailing the different aspects of the art of the book such as book binding, types of paper, calligraphic styles and their importance, reed pens and cutting styles for calligraphy, as well as the construction of dyes, pigments, sizing, and of course, inks. While these treatises almost exclusively focus on traditional Persian crafts, the manuscript researched in this paper is dedicated to the western crafts and recipes which were gathered and translated into Persian by ‘Ali Ḥosseini, a 19th century Iranian scholar. Furthermore, he used the English terms of ingredients and transliterated them in Persian during translation, which can make deciphering the recipes very challenging for the average reader. The current paper focuses on the ink making recipes of the manuscript Kašf al-Ṣanāye‘ translated from European source.

Abstract “A very curious series of paintings in tempera on leather… are to be found at Buckingham Palace.” (Blunt 1946, 267). The 2017 Royal Collection Trust exhibition ‘Canaletto and the Art of Venice’ necessitated the examination and conservation treatment of eight paintings by the artist Marco Ricci (1676–1730). Marco’s artworks were unusually catalogued as ‘tempera on kidskin leather’, however it became apparent that internationally widespread confusion and inconsistency existed in the cataloguing of these artworks, complicating the understanding of these ‘curious’ paintings and the development of a conservation treatment approach. As in-depth material analysis was not possible, multi-collection and art historical research were combined with close observation to better understand the material nature and condition of this unusual group of paintings. The Royal Collection’s group of Marco Ricci paintings on leather is the largest in existence, with all 32 artworks presented in their original frames and it is suggested here that some exist in their original mounted format. This group is therefore the basis of much of the author’s current understanding. Despite presenting a consistent framed visual appearance, the project unearthed surprising variation amongst the Royal Collection works, serving to significantly supplement previous understanding of these paintings.

Abstract Following pilot testing of the effects of alkaline-based nanoparticles on modern parchment, the treatment was extended to historical parchment. This paper describes the application and impact of calcium hydroxide and calcium carbonate nanoparticles dispersed in (i) propan-2-ol and (ii) cyclohexane on a parchment book cover dated 1570. The cover showed signs of damage resulting from contact with iron gall inks and low pH values (∼4–5). Protocols for the damage assessment of collagen in parchment as developed in the IDAP project (Improved Damage Assessment of Parchment) were used to evaluate the impact of the conservation treatments on parchment. Preliminary results have shown that the application of calcium-based nanoparticles did not produce any adverse effects on the state of preservation of collagen. In addition, positive outcomes emerged: the pH was re-adjusted to a neutral value, a strengthening and consolidation effect was observed, and the nanoparticles exhibited a protective action upon artificial ageing of the treated parchment.
