This series includes monographs, research results, and state-of-the-art reviews of conservation literature by Institute staff and others.Discusses the types and causes of stone biodeterioration in hot and humid climates, preventive and remedial methods, selection of chemical treatments, status of current research, and areas for further investigation.
This is a timely volume in view of the considerable interest currently shown in the preservation of our cultural heritage, and the extensive and growing literature on the subject. Unfortunately, the latter is to be found in a wide variety of published sources, some aimed at a very specific readership and therefore not all that accessible to those who need this resource. The present volume draws together a spectrum of biodeterioration work from across the world to provide an overview of the materials examined and the methodologies employed to elucidate the nature of the problems, as well as an extensive and current bibliographical resource on lichen biodeterioration. Biodeterioration of historical and culturally important stone substrata is a complex problem to be addressed. Easy, risk-free solutions are simply not available to be dealt with by other than a wide range of expertise. Successful resolution of this issue will inevitably require a multidisciplinary effort, where biologists work in close cooperation with ecologists, geologists, geochemists, crystallographers, cultural property conservators, archaeologists, anthropologists, and historians in order to recommend the most effective management scheme. The advantage of this approach is obvious: multidisciplinary management teams with good leadership can ask more appropriate questions while developing much more thoughtful and informed decisions.

This open access book offers a comprehensive overview of the role and potential of microorganisms in the degradation and preservation of cultural materials (e.g. stone, metals, graphic documents, textiles, paintings, glass, etc.). Microorganisms are a major cause of deterioration in cultural artefacts, both in the case of outdoor monuments and archaeological finds. This book covers the microorganisms involved in biodeterioration and control methods used to reduce their impact on cultural artefacts. Additionally, the reader will learn more about how microorganisms can be used for the preservation and protection of cultural artefacts through bio-based and eco-friendly materials. New avenues for developing methods and materials for the conservation of cultural artefacts are discussed, together with concrete advances in terms of sustainability, effectiveness and toxicity, making the book essential reading for anyone interested in microbiology and the preservation of cultural heritage.
This handbook is dedicated to the conservation of stone materials by the application of polymers. A short introduction on polymer chemistry is given to highlight their characteristics and properties. After the physical and chemical attributes of stone are summarised, the problems related to its degradation are discussed. Finally, the properties of the various polymers of potential value for stone restoration are reviewed and classified by schemes and tables, and pointers for the future are suggested.This handbook will be of great interest to those who share the author's enthusiasm for stone artworks and her dedication to their restoration and conservation.
Fungi-induced stains on paper are one of the most challenging forms of biodeterioration to study and to prevent; this is because they involve living organisms, and the ways in which fungi respond to changes in the environment and modifications of paper are unpredictable. Yet, there is a great desire among those who encounter fungi on documents, manuscripts, or artwork to remove fungi and clean the paper. This experience in most cases is particularly challenging. What are the reasons behind this challenge? This ground-breaking book attempts to answer this question, among others, by exploring the complex interfacial forces between paper, fungi, and their pigmented secretions which result in bio-stains on paper. Black fungi, collectively referred to as Dematiaceous fungi, were used in this study as a subset of pigment-producing fungi species. The focus is on two, under-studied aspects of the fungi infestation of paper, an interface of fungal pigments and paper, and the impact of light on the production of fungi bio-stains. The results of analytical testing included in this book elucidate the synergistic interactions between the environment, biological clocks of the microorganisms, and secretion of fungal pigments to paper. The black fungal pigment formation is explored in-depth in two scenarios: one that is ‘natural’, when the bio-stains of original artworks have occurred over time by chance, and another, induced by Aspergillus niger, in bio-simulation on known papers in a controlled environment. The findings are intended to provide guidance for preservation strategies, mitigating the biodeterioration of paper, and designing conservation treatment when applicable. The surface of artworks and artifacts is of great aesthetic and artistic importance; conversely, it plays a significant role in governing fungal attachments. In this book, the paper surface is characterized in detail and in correlation with chemical and physical alterations caused by fungal pigmentation. A broad range of analytical instruments was used for surface characterization, such as surface metrology profilometers, a confocal laser scanning microscope, and environmental scanning electron microscope; chemical microanalysis was carried out using X-ray energy dispersive spectroscopy. The novel, three-dimensional characterization of pigmented fungal inclusions and their interaction with paper matrix was studied with micro-X-ray-computed micro-tomography on the synchrotron ESRF. The proposed book is the first to explore the complexity of fungal–paper interactions with the intention to assist professionals working with cultural materials, especially paper-based materials, to make informed decisions when dealing with the fungi infestation of paper.
Examines the application of scientific methods to the study and conservation of art and cultural properties. This work addresses scientific topics of broad interest, cutting across the boundaries of traditional disciplines and attracting up to 250 leadingresearchers in the field.
The cleaning of a work of art often involves removing not only dirt and grime but also unwanted layers of varnish, gilding, and paint from the work's surface. The challenge for conservators lies in finding a cleaning agent that will act on one layer without affecting the layer being preserved and without leaving any harmful residues on the cleaned work. This book, which examines gel cleaning in the treatment of paintings and painted works of art, presents the methodologies, data, and results of a collaborative project of the Getty Conservation Institute and Winterthur Museum. Among the issues covered are the theory and application of gel cleaning systems, the detection of residues left on the surfaces of objects cleaned with these systems, research into solvent-gel and solvent residues, stability of surfactants during natural and artificial aging, and recommendations for formulating gels for specific cleaning tasks.
The book describes hazardous waste industries, sources of waste generation, characterization and treatment processes/ methods and technique and technology to deal with the treated waste as per the prescribed standard.

Stone is one of the oldest building materials, and its conservation ranks as one of the most challenging in the field. The use of alkoxysilanes in the conservation of stone can be traced as far back as 1861, when A. W. von Hoffman suggested their use for the deteriorating limestone on the Houses of Parliament in London. Alkoxysilane-based formulations have since become the material of choice for the consolidation of stone outdoors.^l This volume, the first to cover comprehensively alkoxysilanes in stone consolidation, synthesizes the subject's vast and extensive literature, which ranges from production of alkoxysilanes in the nineteenth century to the extensive contributions from sol-gel science in the 1980s and 90s. Included are a historical overview, an annotated bibliography, and discussions of the following topics: the chemistry and physics of alkoxysilanes and their gels; the influence of stone type; commercial and noncommercial formulations; practice; lab and field evaluation of service life; and recent developments. This book is designed for conservators, scientists, and preservation architects in the field of stone conservation and will also serve as an indispensable introduction to the subject for students of art conservation and historic preservation.
