    Editorial [AICCM Bulletin, vol.43 no.2]
    Tse, N (Taylor & Francis, 2022)
    Dialogues around universal ‘best’ practices in conservation are challenging as are demarkations between the East and West, Europe and Asia, and the global north and south. Institutions, networks of care and materials conservation professionals have thereby struggled with ‘a long-standing epistemological debate about the nature of knowledge and expertise between dominant positivist and alternative non-positivist approaches’ (Beebeejaun et al. Citation2013, p. 2). What works in various geographical contexts is poised against an inherent tension between object centred and scientific processes, to those that are value based and socially situated alongside differences in institutional cultures, developmental histories and disciplinary leader’s foci.

    Editorial [AICCM Bulletin, 41(2)]
    Tse, N (Taylor & Francis, 2020-04-02)
    Papers in this volume focus on geographic locations drawn from Indonesia, Singapore, Taiwan, and the Eastern borders of Australia. In these parts of the world, we all know that there is a long record of active use and conservation of material culture through traditional systems, while the professionalised practice of conservation engendered by its existence, has a relatively recent history.

    Fundamentals of Painting Conservation and Decision Making = พื้นฐานของการอนุรักษ์ภาพ จิตรกรรมและ การตัดสินใจในการอนุรักษ์
    Tse, N ; Poonthongdeewatthana, O (Thailand Academy of Social Sciences, Office of the Permanent Secretary, Ministry of Higher Education, Science, and Innovation, 2023-09-01)
    What is the nature of paintings and paper conservation? The act of conservation asserts values, voice and legitimacy. This leads to questions around what knowledge is important, who gets to decide what is important to conserve, and what form this takes. What is appropriate in localised contexts is often positioned within the aims of heritage and identity, and object-centred practice and scientific processes.

    Justice and Housing
    Halliday, D ; Meyer, M (Wiley, 2024)
    This article surveys various topics that link questions about housing with considerations of economic justice. Housing has received increasing attention from philosophers within the last decade. In political philosophy, some aspects of a topic attract more attention than others. Presently, philosophical reflection focuses on the value of a home; homelessness; gentrification; segregation; and spatial justice, with a substantial body of literature developing on these interconnected themes. We highlight some of the recent contributions to the field of housing justice while also identifying areas that have received less attention. Specifically, we emphasize the importance of further philosophical exploration into how macroeconomic factors, like fiscal and monetary policy, impact housing justice. Additionally, we advocate for normative approaches that underscore justice issues not readily addressed by frameworks prioritizing human flourishing or relational equality.

    Identification of cellulose nitrate based adhesive repairs in archaeological pottery of the University of Melbourne's Middle Eastern archaeological pottery collection using portable FTIR-ATR spectroscopy and PCA
    Noake, E ; Lau, D ; Nel, P (BMC, 2017-01-19)
    A previous study of the Cypriot pottery collection housed in the Ian Potter Museum of Art at the University of Melbourne found approximately two-thirds of adhesive repairs are primarily composed of cellulose nitrate (CN). This is of concern as CN has a limited lifespan (6–20 years), which has implications for the strategic management of the collection. To gain a greater understanding of the prevalence of CN based adhesive repairs in the archaeological context, the original FTIR-ATR spectroscopic survey was extended to incorporate the University’s Middle Eastern archaeological pottery collection. Micro-samples were removed from artefacts using acetone swabs. Analysis of adhesive FTIR spectra identified CN to be present not only as the primary polymer in approximately one-tenth of repairs, but also as a secondary polymer in poly(vinyl acetate) (PVAc) and acrylic adhesive formulations, observed as a weak peak at ~1656 cm−1. CN’s secondary presence in PVAc adhesive formulations is demonstrated using principal component analysis (PCA) and the diphenylamine spot test for CN. Re-analysis of adhesive IR spectra from the Cypriot pottery collection found CN to be present as a secondary polymer in this collection as well. It is concluded a combined methodology of collecting and identifying FTIR-ATR spectra of adhesive repairs from archaeological pottery collections followed by PCA analysis bring to light adhesive formulations which can inform the management of pottery collections.

    Tea: An Alternative Adsorbent for the Preservation of Cellulose Triacetate Film
    Nel, P ; Bell, J ; Newnham, M (Australian Institute for the Conversation of Cultural Material Inc, 2017)
    Cellulose triacetate (CTA) film, the main film base of the Twentieth Century, is inherently unstable, affected by autocatalytic deterioration through hydrolysis. The release of, and subsequent exposure to, acetic acid known as ‘vinegar syndrome’ accelerates deterioration, placing all cellulose acetate materials at risk or actively deteriorating. Preservation techniques rely on cold storage to slow deterioration or microenvironments with adsorbent materials to remove corrosives and/or pollutants. However, commercially available adsorbents can be expensive and difficult to access. This research investigated the potential for tea and tea waste to act as an alternative, low cost, accessible adsorbent for the preservation of CTA film. Adsorption capabilities of various tea varieties and treatments were compared with activated charcoal, silica gel and molecular sieves. Testing established tea as an effective adsorbent of water and acetic acid vapour, with an aversion to adsorption of the plasticiser dibutyl-phthalate. Use of tea waste also involves additional cost, sustainability and accessibility benefits along with lessened corrosive potential. These findings support tea as a potentially viable alternative adsorbent for the preservation of CTA film, requiring further research into optimum application systems.

    A preliminary investigation into the influence of archaeological material on the yellowing of polyethylene storage bags
    Thompson, K ; Nel, P (Routledge, 2021)
    Concerns around the degradation of plastics have been part of conservation discourse for decades. The spotlight is usually on art and objects, and conservation and display materials, however it could be argued that a significant volume of the plastics in museums is associated with storage bags. This study asked whether the condition of plastic storage bags might be influenced by what is stored inside them. If specific materials can be identified as more likely to affect plastic degradation, museums may have a lead-indicator for efficiently monitoring storage risks. This case study developed a methodology for applying multivariate analysis to collected data to answer this question. A subset of polyethylene self-seal bags used to pack archaeological material from the ‘Casselden Place’ assemblage at Museums Victoria was evaluated. Objective data were combined with subjective assessment of bag degradation features gathered during a collection survey and interrogated using multivariate statistical analysis. Results indicate (1) different levels of yellowing are associated with particular plastic bag stocks and (2) ceramic, slate and tile finds are more likely than other materials to be contained within yellower bags. The research points to future enquiry and demonstrates this methodology shows promise for extension to other large cultural datasets.

    Surveys of Plastics in Post-1950 Non-published Book Collections
    Chu, C ; Barrett, M ; Bunn, S ; Zilio, F ; Bell, J ; Nel, P (De Gruyter, 2023-03-03)
    Research over the past three decades has demonstrated that certain plastics in cultural materials are inherently unstable, displaying short lifespans and accelerating the degradation of neighbouring collection materials. Knowledge of the conservation of plastics is increasingly common in museum settings. However, less information is available on conserving plastics found in paper-based collections, and even less guidance on the materials and deterioration of plastic components found in book and document bindings. As plastics have been present in popular bookbinding materials since the mid-twentieth century, collection care professions require knowledge and methods for preserving these materials entering book collections. The aim of this paper is to determine strategies for the care of post-1950s books containing plastic. Collection surveys were conducted to determine the materials, structures, and degradation patterns of non-published books found in archive and archive-like settings at the South Australian Museum, the Art Gallery of New South Wales, and the Grimwade Centre for Cultural Materials Conservation at the University of Melbourne. A methodology combining condition reporting and infrared spectroscopy identified six plastic polymers in 35 binding styles that are summarised as 10 binding types. Recommendations are made for the use of preventive storage strategies responding to four categories of damage.
