World Heritage Patinas

This book presents studies on the management of the Brazilian world heritage and its international counterparts, relating its preservationist practices to the risks and alerts that run its maintenance in the face of so many challenges in the contemporary world. The book has encouraged scholars from a wide variety of disciplines to contribute their valuable knowledge to research on the management and risks of Brazil's world heritage. It is a bold initiative that brings together contemporary studies on management, alerts and risks of the Brazilian world heritage and some international examples. It stands out not only for its interdisciplinary approach, but above all for compiling a wide range of approaches that analyze various dimensions of world heritage management. Unique experience in the management of world heritage allocated to Brazilian territory, this book was written by prominent academics and heritage management professionals and includes national and international case studies. It is a comprehensive academic book in Brazilian world heritage management literature and can therefore be used as an authoritative reference source as well as a significant teaching tool.

‘Artistic/intentional’ patina is a surface layer intentionally produced by an artist or a specialized professional on a metallic artwork with aesthetic or practical purposes. From the science of surfaces point of view the ‘artistic’ patina could be considered as an interface between the metallic substrate and the external environment and therefore affecting, depending on its physical and chemical peculiarities, the corrosion process. In order to understand how the ‘artistic’ patina behaves inside the exposure environment, an experimental activity was carried out: the study of the data collected with the application of different analytical techniques contributed to a more pertinent knowledge of the characteristics of metallic works of art which, in turn, leads to a restoration process respecting their real nature.

The conservation of metallic archaeological and historic artefacts is a major challenge whether they are ancient bronzes or relics of our more recent industrial past. Based on the work of Working Party 21 Corrosion of Archaeological and Historical Artefacts within the European Federation of Corrosion (EFC), this important book summarises key recent research on analytical techniques, understanding corrosion processes and preventing the corrosion of cultural heritage metallic artefacts.After an introductory part on some of the key issues in this area, part two reviews the range of analytical techniques for measuring and analysing corrosion processes, including time resolved spectroelectrochemistry, voltammetry and laser induced breakdown spectroscopy. Part three reviews different types of corrosion processes for a range of artefacts, whilst part four discusses on-site monitoring techniques. The final part of the book summaries a range of conservation techniques and strategies to conserve cultural heritage metallic artefacts.Corrosion and conservation of cultural heritage metallic artefacts is an important reference for all those involved in archaeology and conservation, including governments, museums as well as those undertaking research in archaeology and corrosion science. Summarises key research on analytical techniques for measuring and analysing corrosion processes Provides detailed understanding of corrosion processes and corrosion prevention Discusses on-site monitoring techniques

This collection includes thirty-six important recent works on the effects of pollutants on heritage sites, including thirty papers delivered to the Seville International Workshop on Air Pollution and Cultural Heritage in 2003, and six invited new additions. All papers have been written by a team of leading international contributors and are divided into five subject areas to cover the main topics of interest today. This volume is aimed at archaeologists and molecular biologists as well as advanced students and researchers in the fields of biodeterioration, building materials, micro-organisms and cultural heritage.

The basic principles of corrosion and electrochemistry are briefly summarised to indicate the capabilities of electrochemical techniques in diagnostic and conservation of heritage metals. The basic elements of each electrochemical measurement – cell, electrolyte, instrumentation – are schematically illustrated in the specific application to cultural heritage. The different measurement techniques are reviewed, divided into three groups: (1) potential measurements; (2) DC techniques; (3) AC techniques. The aims and fields of application are discussed, reporting several examples of specific applications in the field of cultural heritage.

Brings together wide-ranging scientific contributions from those who have studied the biological degradation of cultural heritages. It tackles both general topics (mechanisms of biodeterioration; correlation between biodeterioration and environment; and destructive organisms) and specific ones (the problems presented by different materials, environments, climatic conditions, and geographic settings). The contributors also discuss ways to diagnose, prevent, and control deterioration.

Long-standing artworks and monuments show the wisdom and cultural identity of an ancient society along with the educational, material and spiritual merits of the people of that time. However, many historical artifacts and cultural monuments have been eroded over time and are in danger of deterioration beyond repair. There is a need to protect and conserve these artifacts. Restoration and preservation requires a multidisciplinary understanding of the inherent properties of these works based on the type of material and sufficient information in the properties of protective and conservation materials and research methods. Protective Material Coatings For Preserving Cultural Heritage Monuments and Artwork aims to familiarize students with the recent practices in conservation and restoration science in recent years by presenting a modern orientation on the subject focused on material coatings. Readers will be able to understand the properties of different materials in antique objects and how to adopt appropriate treatment methods based on these properties. This book consists of 5 chapters. In the first chapter, materials analysis techniques are described for historical monuments along with coatings used to preserve them. The second chapter introduces the properties of metals, alloys, and their common corrosion and explains protection strategies for metal monuments. An emphasis is given to nanocomposite coatings to prevent decay, especially through electrochemical corrosion. Chapter 3 is devoted to studying natural leather and parchments and their conservation from damage by environmental factors such as UV radiation, temperature, and humidity. The fourth chapter deals with stone works, which are in many historical objects. Chapter 5 introduces the reader to additional preservation materials and innovative methods employed to protect historical monuments and cultural heritage sites. Information about the removal of materials, cleaning of improper prior repairs is also given. Protective Material Coatings For Preserving Cultural Heritage Monuments and Artwork is an ideal book for students of archeology, architecture, materials science and contemporary arts courses who are required to learn about the techniques of preserving antique buildings and works of art. It also serves as a handy reference for professionals and general readers interested in the curation of museums and the conservation of buildings, and cultural heritage sites.

The third International congress of Science and Technology for the Conservation of Cultural Heritage, TechnoHeritage 2017, was held in Cadiz, from 21 to 24 May 2017, under the umbrella of the TechnoHeritage network. TechnoHeritage is an initiative funded by the Spanish Ministry of Economy and Competitivity dedicated to the creation of a network which integrates CSIC and University groups, private companies and end users such as foundations, museums or institutions. The network’s purpose is to foster the creation of transdisciplinary (and not only multidisciplinary) initiatives focused on the study of all assets, movable or immovable, that make up Cultural Heritage. A high-quality scientific programme was prepared, which includes new emerging topics on Cultural Heritage (1) Nanomaterials and other Products for Conservation, (2) New Technologies for Analysis, Protection and Conservation, (3) 20th Century Cultural Heritage, (4) Significance of Cultural Heritage. Policies for Conservation, (5) Deterioration of Cultural Heritage, (6) Biodeterioration: Fundamentals, Present and Future Perspectives and (7) Underwater Cultural Heritage. A special session "Biodeterioration: Fundamentals, present and future perspectives, a session in honour of Prof. Cesáreo Sáiz Jiménez" took place. Our intention was to recognise the work of Prof. Sáiz Jiménez, who recently retired, and its impact on the Cultural Heritage conservation community, which he has helped to promote through numerous activities including, in 2011, the creation of the TechnoHeritage network. This volume publishes a total of eighty-three contributions which reflect the state of the art investigations on different aspects of cultural heritage conservation.
