Abstracts:
Tapestry weaving has been used for millennia to create fabrics in which the design is integral to the structure, but the term ‘tapestry’ is also synonymous with woven pictorial hangings, the subject of this paper. Since the first tapestries were made, they have been cleaned and repaired. As the loss of warp and weft yarns affects both the image and the structure simultaneously, tapestry restoration and conservation techniques have sought to clarify the image as well as support the structure. This paper analyses the evolution of tapestry conservation techniques in western Europe and the United States from the universal use of reweaving to the range of treatments currently employed.

Here is a comprehensive study of the most notorious art forgeries in history: the artists who employed their talents in imitating the talents of others, the dealers who wittingly or unwittingly sold their wares, and the experts who exposed, or were taken in by, their duplicity. Calling upon his substantial professional knowledge and his personal interest in the subject, Sepp Schüller has turned the investigation of art forgeries into a field of lively speculation having artistic, social, and psychological implications.

Thesis: A Study of Ideological Division in the Field of Conservation-Restoration (2006)

Title: Heritage, Hermeneutics and Hegemony - A Study of Ideological Division in the Field of Conservation-Restoration
Author: Frank Hassard
University: Brunel University
Type of document: PhD
Year: 2006

Abstract
In recent times, the concept of ‘intangible heritage’ has gained credence within the international heritage community, reflecting wider concerns relating to the cultural impact of global economic, technological and political forces. For many, intangible heritage represents a vital living mediation of the material past (i.e. tangible heritage) which deepens its significance and meaning-conferring qualities. This thesis explores how in recent times, the intangible heritage became ‘separated’ from the tangible heritage in such a way as to bring about ideological division within the field of heritage preservation and a sense of discontinuity with the past – particularly relating to the practice of restoration and its patrimony of expertise. The thesis argues that this has been attributable to an ‘institutionalised’ conception of heritage based essentially on a historiography of materials located in the ideological site of the museum – the repository where tangible heritage is housed, organised, interpreted, conserved, restored and displayed in such ways as to confer meaning upon the material world. By drawing extensively upon evidence from the literature and engaging the conservation-restoration field, the thesis develops discussion around the emergence (and subsequent institutionalisation) of a relatively recent scientific paradigm of practice – ‘scientific restoration’ – largely shaped by this ‘museological’ vision of heritage. It also considers how the work of Cesare Brandi came to be instrumental in the formulation of this vision but argues that such conceptions have been predicated upon a misappropriation of his ideas and a misreading of historical heritage preservation ideologies that has done much to contribute to tensions evident within the heritage community. To this end, the thesis aims to redress this historical impasse by reconsidering the function of restoration – especially in terms of what is added to the historical document – and reconciling the competing claims of the tangible and intangible by developing the concept of ‘authentic process’.

Safe Handling of Plastics in a Museum Environment (2010)


Title: Safe Handling of Plastics in a Museum Environment
Author: Jia-sun Tsang
Citation: WAAC Newsletter 32(2), pp. 16-22
Year: 2010
Link: http://hdl.handle.net/10088/11186 (pdf, 3.64 Mb)


Abstract:
Research on the theory and mechanics of plastics degradation and conservation has made steady progress over the years, yet regarding the safe handling of plastics, current knowledge and practices are long overdue for an update. The purpose of this paper is to translate the science of plastics degradation into practical guidelines for the safe handling and conservation of plastics in a museum environment. The safety practices outlined here are based on an analysis of naturally aged plastics in museum collections, and are relevant to the specific problems faced by conservators, curators, and museum specialists who must handle and evaluate many types of plastic materials.


Advances in Raman mapping of works of art (2010)

Abstract

Raman mapping can provide molecular information to complement data derived from other analytical techniques in works of art and other objects of cultural significance. Raman mapping can be performed using a motorized microscope stage that moves a sample or an object point by point in two spatial directions. The method can be used both noninvasively in works of art that fit under a microscope objective and in microsamples when, for example, obtaining information on the samples' layering structure is necessary. This paper reports on the development of a Raman mapping approach based on a set of scanning mirrors that direct the laser beam in two spatial directions, vertically through the microscope head or through a horizontal exit on the Raman microspectrometer. The first configuration still has limitations in terms of the size of the work of art that can be analyzed, as it has to fit under the microscope objective, but considerably larger objects can be studied when using the scanning mirrors placed in the horizontal exit. In this paper, the advantages and limitations of these two Raman mapping approaches are compared and discussed on the basis of an example of a contemporary oil painting on canvas.

Abstract
The need to detect a broader range of pesticides and to develop more quantitative analyses has grown as the repatriation of Aboriginal objects has become more frequent and commonplace. This paper summarizes information from literature surveys and object testing that shows the extent and type of pesticide contamination on museum objects. Global objectives for assessing pesticide-contaminated cultural objects are outlined. The most recent developments in X-ray fluorescence spectrometry (a common methodology for detecting inorganic pesticide residues) and the detection of organic pesticide residues such as naphthalene, para-dichlorobenzene, and DDT amongst others are presented. Future steps include developing collaborations that can lead to providing meaningful toxicological assessments of the artifacts to the users along with handling guidelines or recommendations. Mitigation is currently being studied, but not by these authors, and remains an area for future research.

Article: A new reverse-engineering process for contextualizing and digitizing ancient technical objects (2008)


Title: Advanced Industrial Archaeology: A new reverse-engineering process for contextualizing and digitizing ancient technical objects
Authors: F. Laroche, A. Bernard, M. Cotte
Reference: Journal Virtual and Physical Prototyping 3, Special Issue n° 2, 2008, pp. 105-122
Link: archives-ouvertes.fr (pdf, 1.7 Mb)

Abstract:
Since virtual engineering has been introduced inside industries, time processes have been reduced and products are more adapted to customer needs. Nowadays, the DMU is the centre point for all teams: design, manufacturing, communication etc. However, physical mock-ups and prototypes are sometimes requested. Consequently, a back-and-forth action between the real and the virtual worlds is necessary. Our research team has developed a reverse-engineering methodology for capturing technical characteristics of industrial objects but also for capitalizing knowledge and know-how which are required for contextualizing life cycles. More precisely, we work with ancient industrial machines. It is what we call Advanced Industrial Archaeology. Thanks to the coupling of different kinds of 3D digitalization technologies and CAD software, we are able to re-design old industrial objects and old processes. To illustrate our proposal, we will describe one of the experiments we have done with a salt-washing machine which is nearly 100 years old: from the global 3D digitalization of the plant to precise parts design, we have rediscovered the enterprise process and understand its integration in the economic context.

From the Introduction:
The following remarks are based on a long-standing concern of mine and are related to several interventions in the field of industrial heritage. In view of the advent of new parameters - or the recent emphasis on certain trends - these reflections appear to me of the utmost urgency.
On the positive side, there has clearly been a potential increase in the conceptual and spatial field: be it the enlargement of Europe, the increased interdisciplinary and intercultural opportunities, endorsing the idea of the true interconnectedness of our universal heritage, as well as the realisation of the recently recognised status of immaterial heritage.
On the negative side, however, we must lament those ever-increasing, contemptible moves to cash in on culture in the wider sense, moves which reduce culture to a mere pretence, in which performance-mode takes over at the expense of critical discourse (this may well explain the casual approach to methodology which is so often the case); therefore the difficulty in constructing a complete picture, a comparative one, incorporating the requisite hierarchical order.
Without mentioning the worsening risks to climate and the environment, so much so in fact that water, which will figure prominently henceforth, is threatened in its essence, and will be the disputed prize of future conflicts.

Article: Embrittlement of Ancient Silver (2005)


Title: Embrittlement of Ancient Silver
Author: R.J.H. Wanhill

DOI: 10.1361/15477020522294

Abstract:
Ancient silver may become brittle and damaged owing to long-term corrosion and changes in the microstructure. Recognition and determination of corrosion-induced and microstructurally-induced embrittlement, and also their synergy, are important for restoration and conservation of ancient and historic silver. The types of embrittlement are described and illustrated, using examples of ancient and historic silver artefacts, including the famous Gundestrup Cauldron, a masterpiece of European Iron Age silverwork. In particular, the use of automated Electron BackScatter Diffraction (EBSD) enables improved analysis and assessment of corrosion-induced embrittlement. The knowledge obtained from detailed investigations is helpful not only in determining the best ways to restore and conserve embrittled silver objects, but also in defining the possible extent of the embrittlement problem. This is illustrated by a straightforward statistical analysis.
