Almost every museum in the world is confronted with plastics in their collections. Research initiatives and knowledge concerning the conservation of heritage objects made of plastics have proliferated over the last twenty-five years, necessitating this up-to-date, comprehensive resource. Intended as a highly practical guide for the conservation community, this authoritative book offers information essential to understanding plastics, polymers, and rubber/elastomers and their behaviors in the cultural heritage context. Numerous graphs, diagrams, and illustrations allow readers to compare the mechanical, physical, thermal, and optical properties of these substances during conservation. Aimed at the hands-on museum practitioner, this book will assist professionals in choosing the appropriate materials for cleaning, adhering, and consolidating plastic objects-with the result that collections will benefit from a longer lifespan. Complementing the main chapters, fifty-six illustrated "fact sheets" summarize, at a glance, the properties of those plastics most commonly found in museum collections. Six informative case studies present real-world examples of current conservation approaches to works of art and design made of plastics and rubber/elastomers. Under the expert authorship of Thea B. van Oosten, conservation scientist, educator, and internationally regarded authority on the behavior and properties of plastics, this instructive volume is destined to become an invaluable resource for the field.

Reviewing the analytical strategies used in the study of cultural heritage assets such as movable artworks and archaeological items, and immovable objects like mural paintings, archaeological sites and historical buildings, this book pays particular attention to analytical methodology. It is not always necessary to use new and sophisticated instrumentation, what is important is how the instruments are used to obtain reliable, reproducible and repetitive results in view of the problems to be solved. The book considers the influence of the environment on the conservation state including degradation and how modern analytical methods have improved the analysis of materials. It emphasizes multi-method approaches on a range of materials, an approach that is of keen interest to those working in conservation practice. Primarily aimed at final year undergraduate study and masters level students, it would also be useful as supplementary reading for postgraduates and academics who require analytical techniques to enhance their research.

A family business frequently involves enough drama to fill a book - this one in fact.Pearl Sets the Pace tells the story of two landmark companies and a mighty dynasty. It begins in 1883, with the arrival of German brew master Otto Koehler in the bustling city of San Antonio, Texas. He establishes himself as one of the founders of a firm that eventually becomes the Pearl Brewery. In 1914, his murder at the hands of a disgruntled mistress becomes front-page news across the nation. Emma, his grieving (but tough-as-nails) widow, assumes leadership of the company and keeps it afloat during the dark days of Prohibition. In 1941, Margaret Koehler, one of Emma's granddaughters, marries David Earl Pace. After World War II, the young couple formulate a secret recipe for Mexican salsa. Like mad scientists, they experiment in their home kitchen and try out their concoctions on friends. From such humble beginnings grew a mighty enterprise, a real-world manifestation of the American Dream. By the early 1990s, Dave and Margaret's picante sauce was the top-selling Mexican food condiment in the world. Their descendants sold the business to the Campbell Soup Company for $1.1 billion. Through murders and mistresses, Depression and divorces, booms and busts, a passion for product sustained the Koehler-Pace clan. To make something, not simply for their neighbors to buy, but also something that would become integral to their daily lives. That became their defining principle. Yes, it defined them, but it also characterized their city. Can anyone really imagine San Antonio without beer and picante sauce? This is the story of a proud, complicated, and interwoven family and the two great enterprises they wrangled. But it is also the story of a unique Texas city and the people it breeds. It's a business story, a family story, and a story of a thriving, modern city; it is also our story.

Whether antiquities should be returned to the countries where they were found is one of the most urgent and controversial issues in the art world today, and it has pitted museums, private collectors, and dealers against source countries, archaeologists, and academics. Maintaining that the acquisition of undocumented antiquities by museums encourages the looting of archaeological sites, countries such as Italy, Greece, Egypt, Turkey, and China have claimed ancient artifacts as state property, called for their return from museums around the world, and passed laws against their future export. But in "Who Owns Antiquity?," one of the world's leading museum directors vigorously challenges this nationalistic position, arguing that it is damaging and often disingenuous. "Antiquities," James Cuno argues, "are the cultural property of all humankind," "evidence of the world's ancient past and not that of a particular modern nation. They comprise antiquity, and antiquity knows no borders."

Cuno argues that nationalistic retention and reclamation policies impede common access to this common heritage and encourage a dubious and dangerous politicization of antiquities--and of culture itself. Antiquities need to be protected from looting but also from nationalistic identity politics. To do this, Cuno calls for measures to broaden rather than restrict international access to antiquities. He advocates restoration of the system under which source countries would share newly discovered artifacts in exchange for archaeological help, and he argues that museums should again be allowed reasonable ways to acquire undocumented antiquities. Cuno explains how partage broadened access to our ancient heritage and helped create national museums in Cairo, Baghdad, and Kabul. The first extended defense of the side of museums in the struggle over antiquities, "Who Owns Antiquity?" is sure to be as important as it is controversial.

Science and art are increasingly interconnected in the activities of the study and conservation of works of art. Science plays a key role in cultural heritage, from developing new analytical techniques for studying the art, to investigating new ways of preserving the materials for the future. For example, high resolution multispectral examination of paintings allows art historians to view underdrawings barely visible before, while the use of non-invasive and micro-sampling analytical techniques allow scientists to identify pigments and binders that help art conservators in their work. It also allows curators to understand more about how the artwork was originally painted. Through a series of case studies written by scientists together with art historians, archaeologists and conservators, Science and Art: The Painted Surface demonstrates how the cooperation between science and humanities can lead to an increased understanding of the history of art and to better techniques in conservation. The examples used in the book cover paintings from ancient history, Renaissance, modern, and contemporary art, belonging to the artistic expressions of world regions from the Far East to America and Europe. Topics covered include the study of polychrome surfaces from pre-Columbian and medieval manuscripts, the revelation of hidden images below the surface of Van Gogh paintings and conservation of acrylic paints in contemporary art. Presented in an easily readable form for a large audience, the book guides readers into new areas uncovered by the link between science and art. The book features contributions from leading institutions across the globe including the Metropolitan Museum of Art, New York; Art Institute of Chicago; Getty Conservation Institute; Opificio delle Pietre Dure, Firenze; National Gallery of London; Tate Britain; Warsaw Academy of Fine Art and the National Gallery of Denmark as well as a chapter covering the Thangka paintings by Nobel Prize winner Richard Ernst.
