The study aims at clarifying how the different local structure, oxidation state and quantity of copper influenced colour. Analysis of high-resolution Cu-K edge X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS) spectra showed that copper is present as cuprite (Cu2O) in orange samples and as metallic copper in red and brown ones. These phases are responsible for both the colour and opacity of the samples. In addition, Cu1+ ions linked to the oxygen atoms of the glass framework were identified in ratios of about 60% and 30% of total copper in orange and red/brown samples, respectively. In blue and green samples, copper is dispersed in the glass matrix as a mixture of Cu1+ and Cu2+ ions, and no crystalline phases are visible. In this context, the Cu1+ and Cu2+ contents in glass were also quantified thanks to suitable standards, demonstrating that, when Cu2+ is the main chromophorous ion, colour intensity is directly correlated to its content in the glass. In particular, in green and blue samples, coloured by copper, Cu2+ content varies from 26% to 56% of total copper, and the higher contents of Cu2+ are shown by more intensely coloured samples. It should be stressed here that the green colour of the analysed tesserae is given by the physical interaction of blue colour, due to Cu2+ ions, and yellow colour, due to Pb antimonates used as opacifiers.", "publicationTitle": "Journal of Cultural Heritage", "publisher": "", "place": "", "date": "April 2012", "volume": "13", "issue": "2", "section": "", "partNumber": "", "partTitle": "", "pages": "137-144", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1016/j.culher.2011.08.002", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S1296207411000823", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1296-2074", "archive": "", "archiveLocation": "", "shortTitle": "The role of copper on colour of palaeo-Christian glass mosaic tesserae", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Colour", "type": 1 }, { "tag": "Copper", "type": 1 }, { "tag": "EMPA", "type": 1 }, { "tag": "Glass", "type": 1 }, { "tag": "Mosaic tesserae", "type": 1 }, { "tag": "XAS", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2012-10-17T20:44:22Z", "dateModified": "2012-10-17T20:44:22Z" } }, { "key": "HWE4JEJC", "version": 1, "library": { "type": "group", "id": 19621, "name": "Smithsonian Libraries American Art Resources", "links": { "alternate": { "href": "https://www.zotero.org/groups/smithsonian_libraries_american_art_resources", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/19621/items/HWE4JEJC", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/smithsonian_libraries_american_art_resources/items/HWE4JEJC", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/19621/items/T8Z35EPU", "type": "application/json" } }, "meta": { "createdByUser": { "id": 807462, "username": "trinambrown", "name": "Katrina Brown", "links": { "alternate": { "href": "https://www.zotero.org/trinambrown", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "HWE4JEJC", "version": 1, "parentItem": "T8Z35EPU", "itemType": "note", "note": "
