The different color areas were also sampled as microfragments (approx. 1 mm<jats:sup>2<\/jats:sup>) that were studied as taken or mounted in epoxy resin to expose the different paint layers. The microfragments of paint layers and their cross sections were characterized by optical microscopy and scanning electron microscopy coupled with energy dispersive X-ray spectrometry. Furthermore, elemental analysis was obtained with spatially resolved confocal synchrotron radiation \u03bc-X-ray fluorescence spectrometry performed at ANKA synchrotron FLUO beamline. Occasionally, phase analysis by \u03bc-X-ray diffraction was also performed. Results from the different techniques allowed pigment identification and, in some cases, the evaluation of color changes due to degradation processes and, considering the Southern Portugal geology, the identification of their possible provenance. The pigments used were essentially yellow, brown and red ochres, smalt blue, copper green, and black earths, probably from local sources.<\/jats:p>","DOI":"10.1017\/s1431927611000195","type":"journal-article","created":{"date-parts":[[2011,9,5]],"date-time":"2011-09-05T09:43:28Z","timestamp":1315215808000},"page":"702-709","source":"Crossref","is-referenced-by-count":16,"title":["Study of Mural Paintings Using<i>In Situ<\/i>XRF, Confocal Synchrotron-\u03bc-XRF, \u03bc-XRD, Optical Microscopy, and SEM-EDS\u2014The Case of the Frescoes from Misericordia Church of Odemira"],"prefix":"10.1093","volume":"17","author":[{"given":"S.","family":"Valadas","sequence":"first","affiliation":[]},{"given":"A.","family":"Candeias","sequence":"additional","affiliation":[]},{"given":"J.","family":"Mir\u00e3o","sequence":"additional","affiliation":[]},{"given":"D.","family":"Tavares","sequence":"additional","affiliation":[]},{"given":"J.","family":"Coroado","sequence":"additional","affiliation":[]},{"given":"Rolf","family":"Simon","sequence":"additional","affiliation":[]},{"given":"A.S.","family":"Silva","sequence":"additional","affiliation":[]},{"given":"M.","family":"Gil","sequence":"additional","affiliation":[]},{"given":"A.","family":"Guilherme","sequence":"additional","affiliation":[]},{"given":"M.L.","family":"Carvalho","sequence":"additional","affiliation":[]}],"member":"286","published-online":{"date-parts":[[2011,9,5]]},"reference":[{"key":"S1431927611000195_ref007","doi-asserted-by":"crossref","first-page":"110","DOI":"10.1179\/sic.1956.015","article-title":"Cross-sections and chemical analysis of paint samples","volume":"2","author":"Plesters","year":"1956","journal-title":"Stud Conserv"},{"key":"S1431927611000195_ref002","volume-title":"The Pigment Compendium\u2014Optical Microscopy of Historical Pigments","author":"Eastaugh","year":"2005"},{"key":"S1431927611000195_ref009","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/MSF.587-588.1019"},{"key":"S1431927611000195_ref001","doi-asserted-by":"crossref","first-page":"952","DOI":"10.2533\/chimia.2001.952","article-title":"Imaging microspectroscopic, secondary ion mass spectrometric and electron microscopic studies on discoloured and partially discoloured smalt in cross-sections of 16th century paintings","volume":"55","author":"Boon","year":"2001","journal-title":"Chimia"},{"key":"S1431927611000195_ref006","first-page":"78","volume-title":"Pigments of English Medieval Wall Painting","author":"Howard","year":"2003"},{"key":"S1431927611000195_ref008","volume-title":"Artist's Pigments\u2014A Handbook of Their History and Characteristics","author":"Roy","year":"1993"},{"key":"S1431927611000195_ref003","first-page":"54","article-title":"Azurite and blue verditer","volume":"11","author":"Gettens","year":"1966","journal-title":"Stud Conserv"},{"key":"S1431927611000195_ref005","doi-asserted-by":"publisher","DOI":"10.1002\/xrs.1024"},{"key":"S1431927611000195_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/j.nima.2007.05.131"}],"container-title":["Microscopy and Microanalysis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1431927611000195","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,4,10]],"date-time":"2024-04-10T22:42:35Z","timestamp":1712788955000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/mam\/article\/17\/5\/702\/6920175"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9,5]]},"references-count":9,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2011,10]]}},"alternative-id":["S1431927611000195"],"URL":"https:\/\/doi.org\/10.1017\/s1431927611000195","relation":{},"ISSN":["1431-9276","1435-8115"],"issn-type":[{"value":"1431-9276","type":"print"},{"value":"1435-8115","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,9,5]]}}}
