Over the past twenty years there has been a significant increase in underwater activities such as scuba diving which, coupled with the adventure andromance always associated with shipwrecks, has led to rapid developments in the discovery and excavation of shipwrecked material. These shipwrecks are invaluable archaeological 'time capsules', which in themajoriety of cases have come to an equilibrium with their environment. As soon as artefacts on the wreck site are moved, this equilibrium is disturbed, and the artefacts may commence to deteriorate, sometimes in a rapid and devastating fashion. In fact excavation without having conservation facilities available is vandalism--the artefacts are much safer being left on the sea bed. Such famous shipwrecks as the Mary Rose (1545), the Wasa (1628) and the Batabia (1629) have not only brought the world's attention to these unique finds, but have also produced tremendous conservation problems. The treatment of a 30 metre waterlogged wooden hull or large cast iron cannon is still causing headaches to conservators.
During the 1960s, an important find of a group of Viking ships occasioned the building of a new conservation plant of large proportions. This, coupled with a dissatisfaction with previous conservation methods led to the adoption of new methods for caring for waterlogged wooden remains. The methodologies developed are described in this book. English, with Danish Resume.
This is a Foreword by an archaeologist, not a conservator, but as Brad Rodgers says, “Conservation has been steadily pulled from archaeology by the forces of specialization”(p. 3),andhewantstoremedythatsituationthroughthismanual. He seesthisworkasa“calltoactionforthenon-professionalconservator,”permitting “curators, conservators, and archaeologists to identify artifacts that need prof- sional attention and, allow these professionals to stabilize most artifacts in their own laboratories with minimal intervention, using simple non-toxic procedures” (p. 5). It is the mission of Brad’s manual to “bring conservation back into arch- ology” (p. 6). The degree of success of that goal depends on the degree to which archaeologists pay attention to, and put to use, what Brad has to say, because as he says, “The conservationist/archaeologist is responsible to make preparation for an artifact’s care even before it is excavated and after its storage into the foreseeable future”. . . a tremendous responsibility” (p. 10). The manual is a combination of highly technical as well as common sense methods of conserving wood, iron and other metals, ceramics, glass and stone, organicsandcomposits—afarbetterguidetoartifactconservationthanwasava- able to me when I ?rst faced that archaeological challenge at colonial Brunswick Town, North Carolina in 1958—a challenge still being faced by archaeologists today. The stage of conservation in 1958 is in dramatic contrast to the procedures Brad describes in this manual—conservation has indeed made great progress.

The impetus for this book was the desire to systematically organize the extant literature on the conservation of cultural property made of wood, from its beginnings before the Christian Era to the year 2000. Various published reviews and monographs, including Holzkonservierung (Wood Conserva tion) published by the senior author in 1988, have appeared over the years, especially in English and in German. They have provided exemplary treat merit of individual areas or aspects of wood conservation, but a comprehen sive, up-to-date exposition of historic and current developments has been lacking. The diverse professional fields of the authors, as well as their insights into methods of conservation and restoration of wood artifacts in Europe, North America, and Asia provided a solid basis for the success of this under taking. One of the goals during the examination of the literature was that not only well-known conservators and scientists from countries that are leaders in wood conservation should be represented, but that less well-known, often not as readily accessible contributions should also be included. Only in this manner was it possible to draw a comprehensive picture of the national and international state of wood conservation. The Art and Archaeology Technical Abstracts (AATA) of the Getty Institute were very helpful in our efforts to evaluate as many publications as possible.

Waterlogged archaeological sites in Florida contain tools, art objects, dietary items, human skeletal remains, and glimpses of past environments that do not survive the ravages of time at typical terrestrial sites. Unfortunately, archaeological wet sites are invisible since their preservation depends upon their entombment in oxygen-free, organic deposits. As a result, they are often destroyed accidentally during draining, dredging, and development projects. These sites and the objects they contain are an important part of Florida's heritage. They provide an opportunity to learn how the state's earliest residents used available resources to make their lives more comfortable and how they expressed themselves artistically. Without the wood carvings from water-saturated sites, it would be easy to think of early Floridians as culturally impoverished because Florida does not have stone suitable for creating sculptures. This book compiles in one volume detailed accounts of such famous sites as Key Marco, Little Salt Spring, Windover, Ft. Center, and others. The book discusses wet site environments and explains the kinds of physical, chemical, and structural components required to ensure that the proper conditions for site formation are present and prevail through time. The book also talks about how to preserve artifacts that have been entombed in anaerobic deposits and the importance of classes of objects, such as wooden carvings, dietary items, human skeletal remains, to our better understanding of past cultures. Until now this information has been scattered in obscure documents and articles, thus diminishing its importance. Our ancestors may not have been Indians, but they contributed to the state's heritage for more than 10,000 years. Once disturbed by ambitious dredging and draining projects, their story is gone forever; it cannot be transplanted to another location.
Despite the perception that artworks are timeless and unchanging, they are actually subject to biological attack from a variety of sources--from bacteria to fungi to insects. This groundbreaking volume, which publishes the proceedings of a conference held at The Metropolitan Museum of Art in 2002, explores how the development of these organisms can be arrested while preserving both the work of art and the health of the conservator.The richly illustrated text, containing the writings of over 40 scientists and conservators, is divided into sections on stone and mural paintings, paper, textiles, wood and archaeological materials, treatment and prevention, and special topics. The artworks and cultural properties discussed include, among many others, Paleolithic cave paintings, Tiffany drawings, huts built by early Antarctic explorers, and a collection of toothbrushes taken from Auschwitz victims.
This volume highlights recent research efforts in the conservation and investigation of works of art on wood. Through eleven case studies it showcases different experimental methods ranging from X-ray analysis of objects to the study of cross-sections made from micro-samples. New research focusing on the technical study, treatment and assessment of works of art on wood in its many forms is featured in this edited volume. Technical studies include the attribution and investigations of a triptych by Hans Memling and a sculpture from workshop of Michel and Gregor Erhart, decorated Syrian rooms, and investigations of finely carved Gothic wooden objects. Synchrotron-based methods are presented for studying the alteration of 19th c. verdigris in Norway, and multi-analytical methods are employed for the investigations of 16th to 19th c. East Asian lacquer from the Kunsthistorisches Museum in Vienna. Novel methods for the cleaning of gilded surfaces using gels and emulsions are shown, as are innovative strategies for the consolidation for waterlogged wood, providing key data for the assessment of risks and benefits of new methods, and the short and long-term effects on gilding layers and archaeological wood. The book clearly shows how collaboration between engineers, physicists, biologists and chemists and conservators of different types of materials can lead to new research in conservation science. This book is crucial reading for conservators and conservation scientists, as well as for technical art historians, providing key methodological case studies of polychromy from different temporal and geographical contexts.
