Chemical and mineralogical study of a Yamur from the Thirteen Century Gomez-Moron, María Auxiliadora Ortiz Calderón, María del Rocío Ortiz Calderón, Pilar Martín Ramírez, José María Baglioni, Raniero Bouzas Abad, Ana Patrimonio arqueológico Conservación (Patrimonio) Análisis mineralógico Química Yamur Metal The aims of this research were the chemical and mineralogical study of a Yamur from the thirteen Century and the study of their conservation degree in order to facilitate the restoration. The Yamur was located in the upper part of the dome of the Conceptionists Convent in Los Pedroches (Cordoba, Spain). The restoration project was carrying out in the Andalusian Institute of Cultural Heritage (IAPH), according to the silver restoration protocol under the commission of the Andalusian Culture Ministry. The Characterization was carry out by Optical Microscopy (OM), X-ray Diffraction (XRD), Inductively Coupled Plasma (ICP) and Scanning Electron Microscopy coupled to energy dispersive X-ray spectroscopy (SEM-EDX). The spheres are made of brass (copper and zinc alloy) with mi nor proportion of lead. This composition decreases the melting point and allowes the work of the piece. The sphere brass corrosion is due to the presence of cuprite and paramelaconite while the illite found in the deposits could have a soil origin. 2012 2016-07-18T09:01:08Z info:eu-repo/semantics/conferenceObject 978-973-88109-9-0 http://hdl.handle.net/11532/300320 eng https://guiadigital.iaph.es/bien/inmueble/20903 http://certo.inoe.ro/watch/images/proceedings.pdf © Instituto Andaluz del Patrimonio Histórico https://creativecommons.org/licenses/by-sa/4.0/deed.es application/pdf Pedroche Córdoba Bucharest: The National Institute of Research and Development for Optoelectronics (INOE) : The National VillageMuseum "Dimitrie Gusti" Balkan Symposium on Archaeometry "The Unknown Face of the Artwork" (3th. 2012.
