The addition of mordants changed the original colour of the dyes as well as potential patterns corresponding to ΔL*, Δa*, and Δb* such that the variation of lightfastness ranges from 0.25–0.70 units of Blue Wool Equivalence (BWE). Disregarding the effect of mordants, MFT showed that all dyes have lightfastness equivalent to BW3, indicating that they belong in the category of ‘high sensitivity to light’. All dye-mordant combinations vary in lightfastness, such that even the least lightfast dye will have a mordant combination that is more lightfast than the most lightfast dye combined with a mordant that renders it less lightfast. The effect of mordants varies by dye: while one dye may demonstrate a difference in lightfastness of 0.56 units of BWE between the least and most lightfast mordant combination, another may show little or no difference (as low as 0.07 units of BWE). Overall, alum based mordants tend to produce the least lightfast combinations, followed by tin and iron, with copper and chromium producing the most lightfast combinations. This paper shows that there are no simplistic patterns of lightfastness between mordant-dye combinations with these 14 natural dyes. Identifying both dye and mordant is useful to better estimate the lightfastness of a dyed textile.","PeriodicalId":21990,"journal":{"name":"Studies in Conservation","volume":"68 1","pages":"575 - 589"},"PeriodicalIF":0.8,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48466777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They consist of organic molecules such as oils, waxes, gums, sugars, polysaccharides, and proteins that can support the growth of various microorganisms. In this study, in order to identify the microbial community possibly involved in deterioration of paintings in the storeroom of Mouze Makhsus, culturable bacteria and fungi colonizing the paintings were isolated. The identification of isolated bacteria and fungi was performed through morphological analyses and either PCR amplification and DNA sequencing of 16srRNA gene, for bacteria, and ITS genomic region, for fungi. Based on the obtained 16S rRNA gene sequence of bacteria and ITS region sequence of fungi, a phylogenetic tree was constructed using the Neighbor-Joining method. The study also evaluated, in vitro, the cellulolytic activity of the bacterial and fungal isolates. The results highlighted the diverse array of microbial groups colonizing the sampled paintings. Culture-based analyses revealed 27 isolates of bacteria and fungi. Detected fungi fell in seven genera including Aspergillus, Penicillium, Cladosporium, Alternaria, Curvularia, Chaetomium, and Trametes. The majority of isolated bacteria belong to Bacillus genus, whereas to a lesser extent Staphylococcus, Micrococcus, Paenibacillus, Arthrobacter, Heyndrickxia, Priestia, and Rathayibacter were isolated. Qualitative and quantitative assessment of cellulolytic enzyme production showed that the fungal isolates present important cellulolytic activity, and they are potentially dangerous to the paintings.","PeriodicalId":21990,"journal":{"name":"Studies in Conservation","volume":"68 1","pages":"720 - 730"},"PeriodicalIF":0.8,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41501005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The painter’s colour palette was identified in another paper. The panel is now investigated from a technical perspective, discussing aspects related to the support, preparatory system, and paint layer build-up. The research is based on the visual inspection of the painting’s surface with complementary imaging techniques and on the analysis of the materials from the preparatory layers with microscopic and spectroscopic techniques. The characterisation of the painting technique revealed an ingenious use of colour that is based on the understanding of the optical and handling properties of oil paint. This knowledge is illustrated by the painter’s ability to exploit and combine a range of different oil painting techniques, such as glazing, scumbling, wet-in-wet, or wet-in-dry painting; by his formulation of a wide variety of pigment mixtures; and by his use of diverse and often complex layering systems - some quite unconventional for Portuguese painting practice. The material and technical originality of this painting clearly reflects Nunes’ international Roman experience and his desire to update the Portuguese mainstream practice of his time.","PeriodicalId":21990,"journal":{"name":"Studies in Conservation","volume":"68 1","pages":"747 - 759"},"PeriodicalIF":0.8,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49187506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, conservation has evolved from being material- to value-based, developing living heritage, people-centred and people-culture-nature approaches. As conservation interventions on objects, monuments and sites can affect an associated living culture and vice versa, conservators have a responsibility not only to understand tangible and intangible values, but also the local community and practitioners and bearers of tradition, by considering forms of ‘usage’ and ‘interaction’ with objects/monuments, identifying them before practical conservation starts. Whilst often constraining practice, living heritage can enrich professional work by encouraging participation and creativity through generating new, and adapting existing, approaches. This paper examines some (practical) implications of living heritage for conservation practice, by considering the Patan Durbar Square in Nepal, and the emphasis placed on continued use and community connection, to help conservators assume their social responsibilities and increase awareness of this issue.","PeriodicalId":21990,"journal":{"name":"Studies in Conservation","volume":"67 1","pages":"96 - 104"},"PeriodicalIF":0.8,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46098738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
