ItemNo Preview AvailableSpeckle and Conservation(International Seminars, 2008)The aim of this research is to demonstrate the usefulness of speckle, a trait of an expanded laser beam, for the non-destructive testing of artwork in both the imaging of subsurface structure and the quantitative detection of physical movement of canvas. Laser Speckle Contrast Method (LSCI) is a useful method for the viewing of subsurface layers and movement. By investigating the statistical properties of dynamic speckle it is possible to reveal drawings that are hidden beneath scattering layers such as the primary layer of paint or adhered paper. This is achieved by taking a series of speckle images captured in a short time frame and applying one of a number of post processing algorithms. We explore the limitations of this method when applied to various paper samples that have a sketch executed in various media beneath the top layer. The ability to resolve gray scale images was examined as well as looking at the dependence of the contrast of the revealed drawings to the temperature of the surface. Current work is being done on using LSCI to reveal indentations in artwork caused by the application process. The successful use of Electronic Speckle Pattern Interferometry (ESPI) both in the laboratory and in-situ for the detection of in-plane movement of painted canvas due to humidity fluctuations and the out-of-plane movement of paint as it dries has also been demonstrated. Canvas paintings can be very susceptible to movement due to changes of the environment. ESPI is a non-destructive technique yielding sensitive results that can detect displacement on a surface of less than the wavelength of the illuminating coherent light source. While ESPI has been successfully applied to the in-situ study of painted frescoes, previous studies have employed tensile testers as a support for painted canvas. We have shown a portable version of ESPI to be of use in tropical environment in the Philippines, Malaysia and Singapore with original artworks where variations in humidity occur and the samples have not undergone special preparation before analysis, revealing significant directional movements. Furthermore, a simple variation in the direction of beams paths permits the characterisation of out-of-plane movement, specifically as the height of paint shrinks due to the drying process. We have used ESPI to view the drying process of alkyd resin paints over the time period of 24 hours.

ItemPredicting the Past: A critical examination of current art history and conservation curricula.(AiA, 2016)This document is a critical analysis of the current status of art education in art history and art conservation as it relates to the concept of authenticity (as defined as “authorship”). It has been constructed by students and professionals from different specialities and continents. The headline problems, raised by current art history students, have been observed in several art history and conservation programmes by the Work Group, who suggest potential solutions. These are targeted at the Bachelors, Masters, and Doctoral levels.

ItemNo Preview AvailableBuilding evidence for use in criminal cases – standard practice and methodologies: a case study in Australia(AiA, 2014-05-07)In criminal and civil investigations relating to art fraud, the question of how evidence is gathered is as relevant as the question of what is gathered. The sensitive nature of the evidence also means that often the sharing of information between professionals, such as curators, gallerists and art historians is minimal and restricted. Sometimes art historical accounts provided as evidence can be difficult to verify against properly referenced data, while the materials analysis data can be open to various interpretations. In addition, assertions of art fraud have been met with action for libel. As a result, the lack of an integrated analytical and investigative methodology can hamper investigation, making conviction difficult. As an interdisciplinary study conservation is seen to provide ‘objective’ scientific data that can explicate and verify propositions about the source or history of an artwork. Drawing on work undertaken at the University of Melbourne’s Centre for Cultural Materials Conservation (CCMC) this paper discusses the development of standards, methodologies and guidelines for data collection to strengthen prosecution procedures and meet the evidentiary requirements of the courts, and explains why conservation provides the critical and objective procedures useful in bringing forward a successful prosecution for art fraud.

ItemAssessment of the effect of nitric oxide-based treatments on biofilm formation: A comparison with biocides used in paint formulations and the treatment of cultural heritage(Centre National de la Recherche Scientifique, 2013-10-22)Biocides are chemical substances used in the treatment of damaging biological growth. They are commonly added as ‘preservatives’ to paint formulations to prevent biofouling. They are also applied in the control of organisms responsible for the biodecay of cultural material. The demand for sustainable, low-toxic alternatives to conventional biocide use, requires a more sophisticated approach to biocidal systems (Denyer & Stewart 1998). We have investigated how the anti-bacterial properties of the free-radical molecule nitric oxide (NO•), when used in combination with commercial biocides, can enhance their efficacy.

ItemBuilding a legacy in contemporary art in Timor-Leste(Pulido & Nunes; ICOM-Committee for Conservation, 2014)Arte Moris is an artists' collective that was established in Dili after the destruction that resulted in the aftermath of the Popular Consultation. In 2012 a series of interviews were conducted with staff in Arts Moris. These interviews identified youth-oriented art programs as an effective framework for building cultural and educational product in a future Timor-Leste.

ItemEvidence and authenticity: the problem of cultural relativism in conservation decision-making(ICOFOM & ICOM-CC, 2019)Cultural materials conservation is, at its essence, concerned with knowledge transmission, with the construction of authenticity providing confidence in the security of this transmission. Discourse around cultural difference often problematizes attempts to provide singular approaches to conservation decision-making. Examining how an authentic record is constructed in diverse communities in Australia and Southeast Asia demonstrates the use of the same methodologies used to verify authenticity, thereby contesting cultural relativism as a useful construct in conservation decision-making.

ItemNo Preview AvailablePreserving the Past: How to ensure the development of the conservation profession in Australia is preserved for the future(AICCM, 2011-10-19)The first AICCM conference “Conservation in Australia”, which was held in Canberra in 1976 at the Australian National University, was organised by the few conservators located in Canberra. The intervening 35 years have seen changes in the organisation and conservation profession. This 2011 AICCM National Conference, “Conservation in Australia: Past, Present and Future”, now back in Canberra, will allow us to view where we have come from, and examine the challenges for the future development of the AICCM and Australian conservation profession.

ItemSimplicity in Complexity: Trends and Future Directions in Caring for Collections in Australia and Southeast Asia(National Heritage Board, 2019-11-29)Southeast Asia and Australia are characterised by diversity in culture and custom, language, history, climate, religion and belief, methods of government, and economic capacity. Such diversity poses particular challenges for universal approaches to museum development and management, and in particular for practices, policies, and procedures relating to the care of collections. Conversely, diversity provides fertile ground for regional approaches, provided that decisions result from targeted research, the sharing of knowledge and resources, and the development of protocols and procedures that reflect the diversity and acknowledge the various capacities, including in economics, in literacy and language, and in law across the region. In this lecture, Professor Robyn Sloggett examines some of the pressing issues in collections care that need to be addressed across Australia and Southeast Asia, and explores current trends, initiatives and future directions for the care of the rich, diverse, and very important collections that exist in the region.
