Cellulose Nitrate in Conservation

  • Categories: Art

This report attempts to isolate and separately examine each of the factors known to lead to cellulose nitrate decomposition, and then relate their contribution to the instability of the polymer when it is used as a bonding agent for ceramics and as a lacquer for metal objects. These factors include deterioration caused by heat, radiation, or acid impurities, or through the loss of plasticizer. There is, moreover, decomposition caused autocatalytically by the initial breakdown products. In particular, the publication examines new information on chemical changes under ambient conditions that has been developed recently through advances in analytical procedures such as chemiluminescence, X-ray scanning spectroscopy (ESCA), and more sophisticated viscometry. This new information will be added to the large body of data, collected over the past 150 years, on the instability of cellulose nitrate under more severe conditions.

Epoxy Resins in Stone Conservation

  • Categories: Art

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 p...

Inert Gases in the Control of Museum Insect Pests

  • Categories: Art

A serious problem facing museum professionals is the protection of collections from damage due to insects. This book describes successful insect eradication procedures developed at the Getty Conservation Institute and elsewhere, whereby objects are held in an atmosphere of either nitrogen or argon containing less than 1000 ppm of oxygen—a process known as anoxia—or in an atmosphere of more than 60 percent carbon dioxide. Techniques, materials, and operating parameters are described in detail. The book also discusses adoption of this preservation technology, presenting the development of these methods and instructions for building and upgrading treatment systems, as well as recent case histories. The Research in Conservation reference series presents the findings of research conducted by the Getty Conservation Institute and its individual and institutional research partners, as well as state-of-the-art reviews of conservation literature. Each volume covers a topic of current interest to conservators and conservation scientists.

6th International Conference on the Conservation of Earthen Architecture

  • Categories: Art

On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.

Alkoxysilanes and the Consolidation of Stone

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 sci...
