Download or read book Cellulose Nitrate in Conservation written by Charles M. Selwitz and published by Getty Publications. This book was released on 1988-04-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Evaluation of Cellulose Ethers for Conservation written by Robert L. Feller and published by Getty Publications. This book was released on 1991-03-21 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a three-year research program. It describes the chemical character of cellulose ethers as a general class of polymers and establishes an approximate ranking of the relative stability of each generic chemical subclass. Ranking the thermal stability of the polymers with respect to color change and loss in degree of polymerization led to the conclusion that as generic chemical classes, methylcellulose and carboxymethylcellulose appear to be the most stable of the cellulose ethers. Water-soluble ethylhydroxyethylcellulose apparently also possesses good stability. Of questionable long-term stability are hydroxyethylcellulose and hydroxy- propylcellulose. Ethylcellulose and organic-soluble ethylhydroxyethylcellulose proved to be of poor stability, potentially undergoing marked changes in twenty years or less under normal museum conditions. An important additional conclusion reached here, as well as in an earlier investigation, is that considerable variations in stability can occur within a generic chemical class from differences in the basic raw material, a natural product from plants, which is not a uniform, manufactured, chemical substance. Further variations can exist due to different manufacturing processes or commercial sources. Hence, commercial products must be evaluated individually to determine the most stable of a given generic type. Nonetheless, the authors believe the conclusions expressed here to be valid with regard to the relative stability of the generic chemical classes of cellulose ethers.

Download or read book Conservation Treatment Methodology written by Barbara Appelbaum and published by Routledge. This book was released on 2012-05-04 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Treatment Methodology presents a systematic approach to decision-making for conservation treatments. The methodology is applicable to all cultural property, independent of object type or material, and its use will enable conservators to be more confident in their treatment decisions. Conservation Treatment Methodology is illustrated with numerous examples that emphasize the equal importance of the physical and cultural aspects of objects for decision-making. The book also explains how the history of an object and the meaning that it holds for its owner or custodian contribute to determining its treatment. Conservation Treatment Methodology is an essential text for conservators, historic preservation specialists, and restorers, as well as students. Since it is not a technical manual about how to carry out treatments, the book will also be of value to art historians and museum personnel who work with conservators. "This book is unique in its overarching, multidisciplinary approach. The writing is not only clear, but entertaining and engaging." Dan Kushel, Distinguished Teaching Professor, Art Conservation Department, Buffalo New York) State College Barbara Appelbaum is one of the premier objects conservators in the United States and the author of Guide to Environmental Protection of Collections.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation of artefacts and heritage materials is an increasingly popular and fascinating area, spanning both historical and scientific disciplines. Materials come in many forms ranging from sunken ships to tapestries, from buildings to books. With this wide range of matrices and materials to analyse and preserve, an interdisciplinary approach is needed drawing upon skills from many areas of knowledge. Conservation Science: Heritage Materials links these fields of research together forming a comprehensive text book that discusses analytical aspects, wall paintings, organic and inorganic materials. It provides up to date information on subjects including research on decay and degradation and an understanding of the deterioration mechanisms of historic and artistic works. Also included are a number of case studies of particularly important finds including the upkeep of the Mary Rose and the preservation of the sail on Nelsons ship HMS Victory. This book provides an essential guide and reference source for those working in all areas of heritage conservation.
Download or read book Conservation Chemistry written by Ted Lister and published by Royal Society of Chemistry. This book was released on 2004 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into three sections, dealing with the conservation of plastics, stone and wood. It provides teaching and learning materials that deal with familiar chemistry in an unfamiliar context. it also helps to show how the chemical sciences play a part in many unexpected areas of life. Many people think of objects made of plastic as 'throwaway' and do not consider them as collectable items or ones that might be found in museums. In fact there are increasing numbers of plastic objects in museums as well as in private collections and many are increasing in value. To give just one example, some Barbi (TM) dolls can change hands for thousands of pounds. it is also a misconception that plastics do not decay easily - many of them do, and this raises issues about how best to preserve them. This section is set in a context of the collection, care, identification and display of objects in museums and by private collectors. The section on stone focuses on a case study. In order to prevent damage to a stone object, conservation scientists sometiems surround the object with filter paper soaked in pure water. This is called poulticing. Conservation scientists at the British Museum wanted to investigate the poulticing process to see how effective it was at removing salts and to find out whether previous treatment of the stone affected the efficiency of the removal process. The section on wood focuses on the Mary Rose, a wooden Tudor warship that sank off Portsmouth in 1545. In 1982, the hull was raised and since then has been undergoing conservation treatment in a former dry dock at Portsmouth. Over 19,000 artefacts were recovered. The material processed here looks at the chemistry of the decay processes and the methods used to conserve the wood of the Mary Rose's hull and some of the other materials involved.
