The use of cellulose nitrate adhesives in conservation has been criticized and for this reason the stability of the adhesive currently in use has been investigated. The properties of artificially aged samples of the adhesive have been compared with those of artificially aged adhesive-grade cellulose nitrate. The results indicate that the degradation of cellulose nitrate is substantially retarded by the plasticizer in the adhesive. Samples of cellulose nitrate adhesive taken from joins in objects where the date of conservation work is known have been analyzed. The results have been compared with the analysis of the artificially aged samples and a relationship between natural and artificial aging of cellulose nitrate adhesive has been established. The results of this investigation indicate that cellulose nitrate adhesives are...

This phenomenon is called the Russell Effect after its discoverer. In conservation the technique can be used to compare the rate of oxidation of various materials. Three main applications are discussed: detection of watermarks, comparison of conservation treatments and the testing of materials for photograph storage. The effect is thought to be caused by evolution of hydrogen peroxide by materials.

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.

Some analytical techniques use sophisticated apparatus, others use more traditional simple equipment; useful data can be obtained from both types of analysis. The major types of instrumental analysis used in conservation studies are x-ray fluorescence, x-ray diffraction, EDX, gas and liquid chromotography, atomic absorption plasma emission and infra-red spectroscopy. Some of these techniques have made major advances in recent years, examples of the use of these techniques in conservation are described.

Building on the first edition of Conservation Science, this new edition incorporates analytical techniques and data processing methods that have emerged in the past decade and presents them alongside notable case studies for each class of material. An introductory chapter on analytical techniques provides a succinct overview to bring the reader up-to-speed with which type of material each technique is suitable for, the differing sampling techniques that can be employed, and the handling and processing of the resultant data. Subsequent chapters go on to cover all common heritage materials in turn, from natural substances such as wood and stone to modern plastics, detailing the up-to-date techniques for their analysis. With contributions by scientists working in the museum and heritage sector, this textbook will interest students, scientists involved in conservation, and conserv...

Three commercially available cards have been tested and their accuracy found to be similar to the recording thermohygrographs tested.

When a Daguerreotype is made an electrode of such a system, reduction takes only a few minutes. Many of the disadvantages of wet chemical methods are avoided.

The metal is usually present as either a uniform area of leaf or scattered onto the surface in flakes of various sizes. Little information is available on the composition of these particles. Those of yellow metal have been assumed to be gold and those of white metal have been assumed to be silver. When white metal and black particles appear together, the black areas are assumed to be tarnished silver. The aim of this investigation was to analyse these particles and, as far as possible, identify their alteration products. Seven prints and two fan paintings from the British Museum's collection were analysed (Table 1). The metal particles on the surface of one of these prints are shown in Fig. 1. There are huge numbers of these particles; on one print examined, it was estimated that there were tens of thousands. The removal of a few for research purposes presents a negligible aesthetic change. Nevertheless, the number of particles removed was kept as lowas possible, consistent with obtaining a representative sample.

This research project was carried out in order to determine optimal and practical treatment conditions. Light bleaching experiments on artificially aged modern papers and naturally aged 18 th century paper immersed in baths of filtered tap water, deionised water, sodium-based buffers, magnesium bicarbonate and calcium hydroxide at alkalinities ranging from pH 8 to pH 12 of have shown that, in general, solutions at a higher pH are more effective at removing discolouration than solutions at neutral pH values. Filtered tap water and deionised water were significantly less effective than any of the other solutions. Magnesium bicarbonate appeared particularly effective at removing discolouration in the dark as well as during light bleaching when compared to calcium hydroxide at neutral or mildly alkaline conditions. Treatments in calcium hydroxide at higher pH values (pH 10 to pH 12) were sometimes more effective than magnesium bicarbonate but this appeared to depend upon paper type and treatment time. Treatments in the sodiumbased buffers were generally the most effective, suggesting that borax may be an alternative to calcium hydroxide which can be laborious to keep at a stable pH for prolonged treatments. However, great care must be taken to fully rinse sodium tetraborate from the papers after treatment as colour reversion tests have shown that residual sodium tetraborate can lead to excessive discolouration. This report contains unpublished research. Its contents should not be published without the permission of the Keeper of the Department of Conservation, Documentation and Science.
