This book presents a review of research on the use of epoxy resins as consolidants for sculpture and buildings. It deals with both the methods and materials used by conservators, focusing on a detailed chemistry of the materials as well as the practical methods of application. Epoxy resins have been widely used as structural adhesives to repair cracks in commercial and historic buildings, but the application of this technology to the stabilization of fragile stone has generally failed. However, the proper formulation of epoxy systems with solvents has solved problems of viscosity, penetration, crust formation, and discoloration, leading to two different schools of treatment detailed in the publication. Conservators in Europe have concentrated on the treatment of statuary and isolated sections of structures, with alcohol solutions of the resins maintained in contact with the surface for a period of time in order to get deep penetration. In the United States, treatment has focused on stabilizing entire structures or major portions of buildings by spraying them with acetone solutions of epoxy resins. The various techniques of application are discussed and evaluated. The book seeks to provide an expanded inventory of these different techniques allowing the conservator to make informed judgments.

This handbook is dedicated to the conservation of stone materials by the application of polymers. A short introduction on polymer chemistry is given to highlight their characteristics and properties. After the physical and chemical attributes of stone are summarised, the problems related to its degradation are discussed. Finally, the properties of the various polymers of potential value for stone restoration are reviewed and classified by schemes and tables, and pointers for the future are suggested.This handbook will be of great interest to those who share the author's enthusiasm for stone artworks and her dedication to their restoration and conservation.

First published in 1996, this volume has been substantially updated to reflect new research in the conservation of stone monuments, sculpture, and archaeological sites.

Stone is one of the oldest building materials, and its conservation ranks as one of the most challenging in the field. The use of alkoxysilanes in the conservation of stone can be traced as far back as 1861, when A. W. von Hoffman suggested their use for the deteriorating limestone on the Houses of Parliament in London. Alkoxysilane-based formulations have since become the material of choice for the consolidation of stone outdoors.^l This volume, the first to cover comprehensively alkoxysilanes in stone consolidation, synthesizes the subject's vast and extensive literature, which ranges from production of alkoxysilanes in the nineteenth century to the extensive contributions from sol-gel science in the 1980s and 90s. Included are a historical overview, an annotated bibliography, and discussions of the following topics: the chemistry and physics of alkoxysilanes and their gels; the influence of stone type; commercial and noncommercial formulations; practice; lab and field evaluation of service life; and recent developments. This book is designed for conservators, scientists, and preservation architects in the field of stone conservation and will also serve as an indispensable introduction to the subject for students of art conservation and historic preservation.

Winner of the RIBA Book Award, this important and timely publication brings together contributions from leading stone conservation practitioners. It discusses the philosophical principles on which stone conservation is founded and the need to understand the full history and development of a building before starting work. Other topics covered in this book include consolidation, cleaning, and the replacement of stone; conservation of different stone types, including limestone, sandstone, and marble; problems of dealing with polychrome stone; and finally, issues relating to church monuments and graveyards, taking account of the need for good maintenance and health and safety requirements. The book is illustrated with the authors' own examples of stone conservation in practice. Architects, surveyors and craftsmen involved in the conservation of stone structures will find this both a practical and useful reference work.

This series presents current research being conducted under the auspices of the Getty Conservation Institute.An overview of research from 1984 to 1994, including environmental controls in museums, the use of protective materials and analyses in the conservation of cultural objects and archaeological sites, and the use of new technologies for monitoring, documentation, and analysis.

How historical preservation efforts to protect architectural monuments arose in the twentieth century. The twentieth century was highly destructive, but from its landscapes of ruins was born a new architectural type: the cultural monument. In the wake of World War I, an international movement arose which aimed to protect architectural monuments in large numbers, and regardless of style, hoping not only to keep them safe from future conflicts but also to make them worthy of protection from more quotidian forms of destruction. An evolving group—including architects, intellectuals, art historians, archaeologists, curators, and lawyers—grew out of the new diplomacy of the League of Nations. During and after World War II, it became affiliated with the Allied Military Government and was eventually absorbed by the UN as UNESCO. By the 1970s, this organization had begun granting World Heritage status to a global register of significant sites—from buildings to bridges, shrines to city centers, ruins to colossi. Examining key episodes in the history of this preservation effort—including projects for the Parthenon, the Cathedral of St-Lô, the temples of Abu Simbel, and the Bamyian Buddahs —Lucia Allais demonstrates how the group deployed the notion of culture to shape architectural sites, and how architecture in turn shaped the very idea of global culture. Designs of Destruction emphasizes how the technical project of ensuring various buildings’ longevity jolted preservation into establishing a transnational set of codes, values, and practices. At the same time, this paradoxically helped integrate technologies of destruction—from bombs to bulldozers—into cultural governance. Designs of Destruction not only offers a fascinating narrative of cultural diplomacy, based on extensive archival findings; it also contributes an important new chapter in the intellectual history of modernity by showing the manifold ways architectural form is charged with concretizing abstract ideas and ideals, even in its destruction.
