Abstract Historic books are important vehicles for understanding the evolution of human civilisation. To preserve these precious historical materials, unremitting research and exploration has been carried out for thousands of years. The introduction of new concepts and technologies has led conservators to uphold different perspectives on traditional techniques and skills. “Book beating” (chuishu 捶书) is a very special, necessary step in the traditional conservation of ancient Chinese books. However, there is a lack of consensus about how the beating technique affects the structure and long-term stability of paper. In this article, we briefly introduce the origins and basic steps of book beating as well as the precautions required, taking into account the perspectives of conservators on book beating. We then discuss the similarities and differences between book beating and “beat paper”. Analysing a number of characteristics such as the beating strength, paper thickness, and tensile strength of the paper with or without the beating we will explore the pros and cons of book beating. Finally, we put forward some ideas for future research to provide theoretical guidance and support for the conservation of ancient books.

Abstract Valuable books and archival documents are stored in protective packaging, most frequently made of cardboard, in the depositories of archives, libraries, museums or galleries. As part of preventive conservation, the cardboard could theoretically be treated during production with suitable substances delaying ignition or decelerating flaming combustion. This work describes a study of the short-term and long-term effectiveness of selected inorganic additive flame retardants and their influence on the properties of cardboards. Substances containing silicon, boron or hydroxide anions were tested on Prolux solid cardboard and Klug corrugated cardboard. Parameters such as the linear burning rate, oxygen index, heat release rate, weight loss during heating, pH of an aqueous extract, and total colour difference were evaluated. A mixture of mica and bentonite Cloisite-Na+ in a solution of Tylose MH6000 was found to be most useful for this purpose. This mixture doubled the time to ignition of Klug cardboard; in measurements of the linear burning rate, it caused early flame self-extinction for both kinds of cardboard and, simultaneously, had no observable detrimental effect on the stability of the treated cardboard.

Abstract Research over the past three decades has demonstrated that certain plastics in cultural materials are inherently unstable, displaying short lifespans and accelerating the degradation of neighbouring collection materials. Knowledge of the conservation of plastics is increasingly common in museum settings. However, less information is available on conserving plastics found in paper-based collections, and even less guidance on the materials and deterioration of plastic components found in book and document bindings. As plastics have been present in popular bookbinding materials since the mid-twentieth century, collection care professions require knowledge and methods for preserving these materials entering book collections. The aim of this paper is to determine strategies for the care of post-1950s books containing plastic. Collection surveys were conducted to determine the materials, structures, and degradation patterns of non-published books found in archive and archive-like settings at the South Australian Museum, the Art Gallery of New South Wales, and the Grimwade Centre for Cultural Materials Conservation at the University of Melbourne. A methodology combining condition reporting and infrared spectroscopy identified six plastic polymers in 35 binding styles that are summarised as 10 binding types. Recommendations are made for the use of preventive storage strategies responding to four categories of damage.

Abstract This research project examines the effects of X-rays on cellulose and some moulds frequently found on paper. The aim was to identify applications for X-ray irradiation that can be used as a disinfection method for archival material. The question was if X-rays are suitable as an alternative to gamma radiation and if they are less harmful. For this purpose, the minimum X-ray dose required to reduce the microbial count to a harmless level was determined. The material-altering effect was examined on samples treated with X-rays and gamma radiation. Spectrophotometric measurements showed that there is no noticeable colour change with either type of radiation. The determination of the molecular weight distribution, in turn, showed that the molar mass of the cellulose is considerably reduced with both treatment methods. Using mechanical tests, however, it could be demonstrated that this has no significant influence on the tensile strength. The examination of the oxidation behaviour also showed no significant difference between the differently treated samples. The studies demonstrated that both methods have an almost identical effect on cellulose. Thus, X-ray treatment is primarily a supplement to the known disinfection methods and is particularly suitable for objects that would not withstand treatment with alcohol.

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.
