Raman Spectroscopy In Cultural Heritage Preservation

This book addresses the application of Raman spectroscopic techniques to a range of diverse problems which arise in the study, conservation and restoration of artefacts and sites closely related to our cultural heritage as well as in authentication. These themes are naturally wider than what at first might be considered as artworks and archaeological artefacts and the topics include pigments, paintings, ceramics, glass, sculpture and patination / corrosion, textiles, industrial archaeology, the degradation and preservation of biomaterials, mummies and human skeletal remains. An interesting feature is the inclusion of modern case studies which describe specific problems and approaches to the Raman spectral analysis of items important to our cultural heritage. The text is prefaced with an introduction to the important parameters used in nondestructive Raman measurements and also highlights some future applications based upon novel miniaturised instrumentation for in-field studies and potential screening work which will identify specimens which would repay further studies in the laboratory. An attempt is made to give a snapshot of the state-of-the-art evolution since the beginning of the technique (1970s) and to point out potential further development. The book is co-edited by three international experts with many years' experience in the application of Raman spectroscopy to artworks, archaeological artefacts and in the investigation of materials and sites for cultural heritage preservation and each editor has undertaken to write individual chapters and different topics personally. The adopted approach is designed to convey the sort of information which has become available from the adoption of analytical Raman spectroscopy to different problems in the field of cultural heritage preservation through the spectral interrogation of artefacts and how the interpretation of the spectral data can assist museum curators, archaeologists and cultural heritage historians in the preservation and conservation of ancient materials and sites : a particular advantage in this respect is the ability of Raman spectroscopy to determine –generally in a strictly noninvasive procedure - at the laboratory or on-site with mobile instruments, the presence of both organic and inorganic components in a particular specimen together nondestructively without any chemical and mechanical pretreatment being undertaken, which is an essential requirement for rare and valuable samples . An important aside from this work is the means of spectral identification of ongoing biodeterioration and biological colonisation in specimens in storage and the effects of environmental deterioration such as humidity and temperature upon their integrity.

Conservation Science is a rather innovative application of instrumental analysis with steadily increasing importance. Although the first attempts for preserving material from the cultural heritage on a scientific basis are found in the 19th century pioneer chemistry years, only the use of sophisticated physicochemical techniques results in effective identification and deterioration studies of monuments and objects, and in reliable intervention procedures. This volume allows to gain solid knowledge and improved skills on the ways separation schemes and diagnostic methodologies are applied in the safeguarding and authentication of tangible works of art; as well as on the modes of implementing novel safeguarding practices built on well-established principles – such as the use of laser in the decontamination of objects. All techniques are covered at a state-of-the-art level; while selected applications permit addressing major groups of materials and artefacts. Conservation Science is nowadays taught at master’s level in all developed countries, and museum laboratories increasingly adopt scientific approaches in their restoration initiatives. The book is intended as a valuable tool for students and professionals active in these frames. In addition, it provides an indispensable manual for participants in the specialized intensive courses, which are systematically offered by the authors under the auspices of the relevant European network.

Ten years after the first volume, this book highlights the important contribution Raman spectroscopy makes as a non-destructive method for characterising the chemical composition of objects with archaeological and historical importance. The original book was ground-breaking in its concept, but the past ten years have seen some advancement into new areas, consolidation of some of the older ones and novel applications involving portable instrumentation, on site in museums and in the field. This new volume maintains the topic at the cutting edge, the Editors have approached prominent contributors to provide case-studies sorted into themes. Starting with a Foreword from the British Museum Director of Scientific Research and an Introduction from the Editors, which offer general background information and theoretical context, the contributions then provide global perspectives on this powerful analytical tool. Aimed at scientists involved in conservation, conservators and curators who want to better understand their collections at a material level and researchers of cultural heritage.

With the maturation of laser technology in diagnostic and conservation applications, conservation scientists, archeologists, art historians, researchers, and advanced science-oriented students now have the tools necessary for preserving the future of our past-our cultural heritage. Presenting recent developments in the field, Lasers in the Preservation of Cultural Heritage: Principles and Applications addresses the basic concepts of laser applications and supplies case studies of analytical, structural diagnostic, and laser cleaning applications. The book provides a comprehensive presentation of the fundamental principles and applications of modern laser technology in the analysis of composition, diagnostics of structural integrity, and conservation of artworks and antiquities. Beginning with an introduction to the basic techniques used in art conservation and archeology, the book describes the fundamental aspects of laser-matter interactions, emphasizing laser diagnostics and laser processing applications. The next few chapters focus on laser-based spectroscopic techniques for the analysis of the composition of materials in art and archaeology, including laser-induced breakdown, Raman, and laser-induced fluorescence spectroscopic techniques. The book proceeds to highlight nondestructive diagnostic techniques, laser processing applications, laser applications for the cleaning of paintings and stone, and methods for the removal of encrustations. It concludes with case studies for the conservation of materials like parchment, paper, metal, ivory, and wood, and includes conservation approaches for modern paintings. Bridging science with art, Lasers in the Preservation of Cultural Heritage presents a systematic overview of the fundamentals and applications of laser techniques in artwork conservation and archeological science.

Laser techniques offer possibilities for the examination and conservation of artwork, and for the prevention of cultural heritage. This collection of peer reviewed papers from the 8th International Conference on Lasers in the Conservation of Artworks, Sibiu, Romania, September 21-25, 2009, addresses various aspects of cultural heritage preservation

Spectroscopic methods such as Raman are used to investigate the structure and dynamics of matter. They are essential for the study of the different types of mineral or organic materials produced at the Earths surface or interior. As a result of technological improvements in gratings, detectors, filters and personal computers in the last decade, many micro-Raman spectrometers have become plug-and-play instruments, very easy to use and available at a lower cost than the early Raman microprobes. Thus, many laboratories in Earth Sciences and Cultural Heritage are equipped with these new spectrometers. Commercial, portable Raman spectrometers working in the field have also contributed to the spread of Raman spectroscopy. Poor levels of education in terms of Raman spectroscopy in undergraduate courses in Earth Sciences make it difficult for individuals to obtain information of the highest quality relevant to Earth sciences and Cultural Heritage. This volume is, therefore, timely. Four main topics are addressed: Theory; Methodology, including the instrumentation; Experimental aspects; and Application.

With contributions by scientists working in the museum and heritage sector, this textbook provides an overview of the analytical techniques and data processing methods used in modern conservation science. Each chapter deals with one of the common types of conservation materials in turn and provides case study examples of the techniques employed. It will interest students, scientists involved in conservation, and conservators who want to develop their understanding of their collections at a material level.
