Obvious colour changes in the papers and loss of colour in the inks and in pink/red pigments where display mounts have protected the edges prompted materials analysis, microfading and an investigation of their history. The decisions made for their display are discussed in the context of Tate’s lighting policy, currently being reviewed to cover all types of material in a growing collection of modern materials, and changing attitudes to the display or not of preserved colour beneath earlier mounts and frames. The materials van Gogh used were very typical of his known choices at the dates of making. The use of two formulations with geranium lakes based on Eosin Y, both sensitive to light, were identified in a gouache by this artist for the first time.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"46 1","pages":"3 - 22"},"PeriodicalIF":0.8,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48732663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Iran, due to the prevalence of both modernity and nationalism at the beginning of the twentieth century, a period of extensive restoration of historic buildings was begun. The aim of this study is to identify the implicit principles of that restoration, and it is argued that it had its own characteristics due to the unfamiliarity in Iran with European approaches to conservation. Case studies were used to provide data for analysis to identify the principles and themes guiding the restoration. These included effecting the ‘perfection or completeness of the architectural work’, ‘decoration and beautification’, ‘harmony’, and restoration that exemplified ‘traditional art’ and ‘traditional proficiency’, all of which indicate a similarity with the characteristics of ‘stylistic restoration’, the purpose of which, according to Viollet-le-Duc, was to reinstate a building in a complete and ideal condition. This approach is interpreted as being in accordance with the prevalence of nationalism both in Europe and Iran, but where modern principles such as readability and minimal intervention were disregarded in the Iranian approach to such restorations.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"46 1","pages":"37 - 49"},"PeriodicalIF":0.8,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49495602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these artefacts have always been associated with the beliefs, spirituality and philosophy of the Ashanti people and they are numinous or sacred objects venerated by both the museum's staff and its visitors. This article explores the phenomenon of numinosity surrounding selected objects in the collections and the impact this has on their preservation. It uses qualitative tools to explore case studies, including their detailed study, and interviews with people knowledgeable about their use and sacred status. A major finding the authors report is that numinous artefacts in the museum were not created as aesthetic objects but primarily for religious and utilitarian purposes that correlate with the devotion of the people involved. Their numinosity was also found to contribute to their preservation by protecting them from handling and use by visitors and museum personnel. The article is offered as a contribution to the literature both to stimulate similar research and widen the interests of those involved in the care of cultural heritage by situating such artefacts in cultural traditions that are arguably left largely outside the field of museology and yet are still to be fully explored in most parts of Africa.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"45 1","pages":"223 - 235"},"PeriodicalIF":0.8,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45615576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Giving weight to the term ‘treatment skills’, this article acknowledges the function of conservation treatment skills as a core conservation competency. It examines the nature of commentary that has sought to demonstrate that this competency has been reduced by a lack of focus on treatment skills in conservation education and, in turn, that this affects student skills and employability. It assesses the evidence on which this discourse has been developed, and in doing so considers the provocative and consequential nature of the discourse as it relates to conservation students and recent graduates. The article concludes that conservation, as a maturing discipline and profession, is defined by a technical, social and intellectual pluralism, and that this is more realistically the challenge for conservation education to advance in the twenty-first century.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"45 1","pages":"157 - 172"},"PeriodicalIF":0.8,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60417663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kemp","doi":"10.1080/19455224.2022.2130548","DOIUrl":"https://doi.org/10.1080/19455224.2022.2130548","url":null,"abstract":"The final issue of the 2022 volume of the journal begins with three articles that in their own ways address the perennial question of what kinds of skills educators should emphasise in their curricula for teaching conservation. Robyn Sloggett’s article, ‘Conservation skills’, takes the bull by the horns to wrangle out the differences between what educational institutions can and do provide and what employers and other agencies involved in conservation might be expected to contribute towards. Against the notion that graduates somehow lack core competencies in ‘treatment skills’—as has variously been suggested in recent years—Sloggett argues that contemporary conservation skills have been reconfigured by a technical, social and intellectual pluralism, and embedding this in the curriculum is the real challenge for conservation education to advance in the twenty-first century. Sloggett’s argument is followed by Salvador Muñoz Viñas’, ‘Conservation science, conservation practice and the conservator’s knowledge: a naïve exploration’, in which he suggests that in making decisions about treatments conservators draw on a reservoir of tacit knowledge which can only be developed in the workplace rather than in an educational setting. He argues that even where conservation is made more ‘factual’ through science such an approach is always redundant in the decisionmaking that conservators typically execute when caring for something. To illustrate this he presents a case study and navigates 42 treatmentrelated questions to demonstrate how science proves insufficient in answering any of them. He concludes that it is the tacit build up of experience, primed in training but developed in the workplace, that allows the conservator to answer such questions and concomitantly moves the individual along the novice-to-expert axis. That skills and know-how are best developed in the workplace is further corroborated by Grace Barrand and Marcelle Scott’s contribution, ‘Targeting specialist skills through Work-Integrated Learning: a case study in frames conservation at the Art Gallery of New South Wales’. Progression along the novice-to-expert axis is played out across Barrand’s structured mentorship at AGNSW where her skills were actively developed in a series of tasks designed by staff in the frames conservation department. Using a Work-Integrated Learning approach over 12 months they targeted developing Barrand’s cognitive skills such as muscle memory and pattern recognition to consolidate and improve her professional competencies. The positive results suggest support for Sloggett’s argument for more structured input from industry and offer an industry relevant training model for others to adapt to address any gaps they see in the skillset of their new employees.

However, due to historic or aesthetic value, PVC-P book covers in paper-based collections cannot always be removed or replaced. There is currently a gap in the literature addressing strategies for storing PVC-P associated with paper materials. Prompted by a case study of the Chinese artist Yang Zhichao’s Chinese Bible (2009)—a performance installation artwork of 3000 notebooks including approximately 1000 notebooks with PVC-P covers—three potential interleaving materials (Mylar®, Hollytex® and buffered tissue) were tested to simulate use during long-term storage. Notebooks and PVC-P book covers were purchased and assembled to model stacked storage conditions, and thermally aged at 70°C and 50% relative humidity for 130 days. Before and after ageing, samples were analysed using visual examination techniques, ATR-FTIR spectroscopy, colourimetry and weighing. It was found that all three interleaving materials lowered the probability of ink offsetting. However, cover deformation and a blotchy surface haze were more commonly observed in interleaved samples compared to non-interleaved samples. More research is necessary to identify a suitable strategy to manage PVC-P degradation in close contact storage with paper materials. This study contributes to a better understanding of the storage of plastic-covered books that may be found in libraries and archives, highlighting the complexity of conserving plastic and paper composite materials.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"45 1","pages":"204 - 222"},"PeriodicalIF":0.8,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44280214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are both theoretical and practical problems with any such belief including things like the limits of inductive knowledge, the unrepresentativeness of samples and the disjunction of reality inherent to the scientific paradigm. Perhaps more importantly, there are many areas in conservation practice that fall beyond the purview of science as they can only be successfully approached by resorting to a kind of knowledge (or intuition, or skill) that is unique to conservators. The relevance of this knowledge can be demonstrated by carefully examining the questions that a practising conservator needs to answer when performing a conservation treatment.","PeriodicalId":43004,"journal":{"name":"Journal of the Institute of Conservation","volume":"45 1","pages":"173 - 189"},"PeriodicalIF":0.8,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44303317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
