Authors:Aive Viljus; Mart Viljus Abstract: This article deals with archaeological find material with a low silver content and the problems of conserving such material. The aim of the research was to find the most suitable method for the conservation of poorly preserved early post-medieval period coins with varying composition. For this, first, the composition of both the metal and the corrosion products of the archaeological coins were analysed, after which comparative experiments of different cleaning methods were carried out in order to find out the least harmful and most efficient method. A test was also performed to determine the necessity and efficiency of stabilizing the surface of the coins after cleaning. PubDate: Wed, 20 Feb 2013 14:55:18 +010
Authors:Emma Marie Payne Abstract: New imaging techniques are increasingly being used within cultural heritage. This paper explores potential uses of such technologies within conservation and implications of their use on object preservation and accessibility. Study of their effects on objects is crucial because their employment is becoming irreplaceable; for example, polynomial texture mapping (PTM) has revealed previously undetectable surface features. In such cases, it is necessary to continue to use the technique to monitor object condition.3D laser scanning, PTM, and CT scanning are investigated. Case studies are explored to investigate their current role in cultural heritage. The appropriateness of this role and whether it should be expanded is addressed by analysing advantages and disadvantages of the techniques, their feasibility, and risks caused to object preservation and accessibility.The results indicate that the technologies present some advantages over standard digital photography; PTM in particular is found to be an extremely useful, affordable technique. A more established role within conservation, especially for condition assessments, could be worthwhile. Use of the imaging techniques to create models for exhibition can also be advantageous; however, care must be taken to ensure that such models are used to enhance accessibility to original objects and not to replace them.

Authors:Tracey Sweek; Julie R Anderson, Satoko Tanimoto Abstract: Excavation of a 2000 year old Amun Temple at Dangeil in Sudan. Under the directorship of Drs Salah Mohammed Ahmed of the National Corporation for Antiquities and Museums, Khartoum and Julie R Anderson of the British Museum, London an excavation of the temple commenced in 2000. Dangeil is located to the south of the 5th Nile cataract in Sudan. In 2008, a preliminary visit was organised to intiate a conservation programme and trials to the architectural fabric of the temple. The materials used in the temple's construction include mud brick, fired brick, lime plaster and sandstone. During the subsequent seasons following 2008 adjustments and evaluations of the previous year's completed trials have been assessed. This case study outlines the progress of the site to date.

Authors:Titika Malkogeorgou Abstract: This paper is an anthropological study on conservation and museum practice, interrogating the negotiative value of conservation. It is asking who’s worth consulting when dealing with the preservation of complex museum objects, when a source community is a legitimate contributor to object conservation, and what are the ethical considerations posed for conservators confronted with such cases. Conservation is capable of bringing together more disciplines in the care of objects and creates a process of re-evaluation through technical analysis and treatment. I will discuss this process and what it may mean for the secular museum through the case study of a copper alloy Tibetan Buddha sculpture at the Victoria and Albert Museum. The debate around the object ultimate involved conservators, curators, heads of departments, local Buddhist representative, the director, and the museum trustees to decide on the extent of the intervention. This is a case study which challenges the character of the object, it reveals the object’s affective value and how the object’s meaning may change according to context and people. It questions the role of the conservator, the relevance of source communities and how the host institution influences conservation as it follows changes in concept and approach to museum objects.
