Gr\u00e2ce \u00e0 une collaboration entre la HE Arc CR et le Laboratoire des technologies d’assemblage et de la corrosion du Laboratoire f\u00e9d\u00e9ral d’essai des mat\u00e9riaux et de recherche \u2013 Empa (D\u00fcsseldorf), l\u2019Universit\u00e9 de Florence, l\u2019Opificio delle Pietre Dure (Florence) et le Mus\u00e9e historique de Lausanne, nous avons pu r\u00e9unir des informations historiques sur l’apparence de la surface des objets, pr\u00e9ciser le niveau de nettoyage optimal \u00e0 atteindre, \u00e9tudier les diff\u00e9rentes formes de ternissement, comprendre les m\u00e9canismes du nettoyage \u00e9lectrolytique et d\u00e9velopper des m\u00e9thodes de traitement optimis\u00e9es.<\/p>\n\n\n\n
