Book Description
Conservation treatments, while focused on preserving the physical form of a ceramic vessel, may inadvertently have a negative impact on other information stored in preserved organic residues that may remain on or in the object. This research investigates the effect of common conservation treatments on the preservation of organic residues in order to better understand how conservation treatments commonly used in the field and laboratory can affect the integrity of organic residues in archaeological ceramic sherds. Olive oil, an organic residue that is frequently found in the archaeological record of the Near East, was applied in an experimental setting to the surface of archaeological ceramic sherds. The sherds then underwent various conservation treatments, such as mechanical cleaning, soaking in water over various periods of time, and acid cleaning. Residue retention was quantified by organic extraction followed by gas chromatography-mass spectrometry (GC-MS) analysis. The results suggest that increasing the soaking time of a sherd in water decreases the amount of residue retained, and the addition of mechanical cleaning further reduces residue retention. The data gathered from this study can assist in predicting the condition of organic residues on ceramics based on previous conservation treatments and shed light on the integrity of organic residues on previously conserved objects.

Book Description
Annotation "Over the years, archaeologists have developed a number of techniques for conserving historical artifacts for future generations. Along with these techniques, researchers have developed a series of ethical principles for treating materials in a way that allows them to be not only observed and analyzed for the present, but also re-studied in the future. Conservation techniques used up to now, however, have provided artifacts only a limited lifespan, and in some cases they do not work well with waterlogged materials. Within the past few years, archaeological chemistry and concerns of longevity testing have become central issues in the development of conservation treatment strategies." "Working with Dow Corning Corporation, Texas A&M's Archaeological Preservation Research Lab (APRL), and the Conservation Research Lab (CRL), Smith and his colleagues in AS&M's Nautical Archaeology Program set out to develop a series of chemistries and techniques that would provide successful and affordable treatment strategies for organic materials. In this ground-breaking description of the processes and materials that were developed, Smith explains these techniques in ways that will allow museums and historical societies to conserve more stable artifacts for traveling exhibits and interactive displays and will allow researchers to conserve new discoveries without sacrificing important information." "Beyond the advantages offered by polymer replacement (Passivation Polymer) technologies, Smith considers a concept seldom addressed in conservation: artistry. Variance in equipment, relative humidity, laboratory layout, intended results, and level of expertise all affect researchers' ability to obtain consistent and aesthetically correct samples and require a willingness to explore treatment parameters and combinations of polymers." "Smith prescribes an effective layout for day-to-day conservation of small organic artifacts and then examines some of the mechanical techniques used to process various organic materials from marine and land sites. He concludes with an exploration of new tools and technologies that can help conservators devise more effective conservation strategies, including CT scans and Computer Aided Design images and stereolithography." "All archaeologists, conservators, and museologists working with perishable artifacts will benefit from the careful explication of these new processes, and those wishing to incorporate some or all of them will find the step-by-step instructions for doing so."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Organic residues include a broad range of materials that can be analyzed at a macro-, micro- or molecular level. They represent the carbon-based remains (in combination with H, N, O, P and S) of fungi, plants, animals and humans. Organic residue analysis is a relatively new technique to archaeology. The chapters of this volume bring together scholars from across the globe and attest to the diverse range of analytical methods, material types, spatio-temporal cultural units and research questions to which organic residue analysis has been applied. They are partly the proceedings of a symposium on this subject, held on 31 March 2005 in Salt Lake City (Utah) during the 70th Annual Meeting of the Society for American Archaeology, and partly the result of invitations to contribute forwarded to many active in this field.

Book Description
This document provides guidance for good practice in the recovery, analysis and publication of organic residues from archaeological sites. It has been written for a range of archaeological professionals, including local authority archaeology officers, archaeological units and consultants, project managers, museum curators, conservators and pottery specialists, with the aim of ensuring that approaches are suitable, cost-effective and informative. The objectives of the guidelines are to: * inform practicing archaeologists of the principles and potential applications of organic residue analysis (ORA) * provide clear and coherent guidance on organic residues recovery, sampling and analysis * demonstrate the research potential of the approach The Supporting Information document contains further detail on terms and concepts used in ORA and analytical techniques used to identify organic residues, together with guidance on where future research themes involving ORA might usefully be targeted. A thematically organised bibliography and details of where to access literature relating to ORA is also included. It also incorporates a short section on reporting, publishing and digital archiving, and guidance for museum curators and conservators in archiving ceramics with potential to be used for ORA.

Book Description
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.
