    Speckle and Conservation
    Miles, E ; Roberts, A ; Tse, N ; Sloggett, R (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.

    Authenticity, Instagram and the artist archive: Contemporary approaches to building a secure artist record in Indonesia
    O'Donnell, E ; Sloggett, R ; Tse, N ; Bridgland, J (ICOM CC, 2021-05-17)
    The circulation of counterfeit paintings in In- donesia’s art centres remains, as it does across the globe, a sensitive issue that distorts the cul- tural narrative and threatens the intellectual property of artists and their legacy. This paper focuses on contemporary Indonesian artist Heri Dono and the methods which he has adopted to protect his intellectual property in response to counterfeit paintings on the market bearing his signature. In 2015, Dono established a personal archive at his studio in Yogyakarta in which he has documented his artistic production since 1979. In 2017, in parallel with the development of the archive, the Studio Kalahan Instagram account began publishing images of counterfeit paintings in Dono’s signature style. Informed by interviews with Dono and other contem- porary Indonesian artists, this research aims to understand issues surrounding the veracity and legacy of the physical and digital archive and in- tegrated ways of building a secure artist record.

    Authentication in a legal framework: Methodologies that underscore art authentication in practice
    Morden, A ; Sloggett, R ; TSE, NA ; Bridgland, J (International Council of Museums, 2014-09-14)
    The ideal of art authentication in practice stems not solely from a need to protect market interests, but from a need to protect the interests of artists and the integrity of their artistic legacies (Spencer 2004). This paper looks at the legal context for the methodologies that underscore art authentication in practice, and the legal framework that should preposition the gathering of evidence, external to a court proceeding. Essentially, it seeks to explore the question: Should the potential for litigious action bind the process of art authentication to a legal evidence-based framework? This paper is presented with regard to the investigations of the oeuvre of the contemporary Australian artist Howard Arkley (1951–1999), currently being undertaken as part of the author’s PhD thesis at the University of Melbourne, Australia.
