Cette  œuvre  d\u2019une  grande  richesse appartenait à la collection d\u2019orfèvrerie religieuse du baron Adolphe de Rothschild qu\u2019il légua au Musée du Louvre à sa mort, en 1901. L\u2019étude historique et technique du baiser de paix nous fait voyager à travers les époques et l\u2019univers des orfèvres-émailleurs du Saint-Empire romain germanique au XVe siècle, jusqu\u2019au XIXe siècle, en France, dans le milieu des grands collectionneurs parisiens. Remaniée aux goûts des époques (XIXe) et des pays qu\u2019elle a traversés, cette œuvre questionne sur la notion « d\u2019authenticité ».  Jamais restaurée depuis son entrée au Musée du Louvre, cette pièce d\u2019orfèvrerie, témoin des grands édifices  gothiques  médiévaux,  présentait  des  altérations  rendant  difficile  sa  compréhension  et  la lisibilité  de  ses  décors,  notamment le  relief  de  saint  Georges  présenté  au  cœur  de  l\u2019édicule.  Le caractère  composite  de  l\u2019objet,  sa  morphologie  et  l\u2019impossibilité  de  démonter  le  groupe  central rendaient complexe le nettoyage de ses surfaces ternies. Ces problématiques ont orienté notre choix de  sujet  technico-scientifique  vers  le  nettoyage  électrochimique  de  l\u2019argent  terni  couplé  à  un complexant. La technique électrochimique a pu être appliquée au baiser de paix permettant ainsi de retrouver  une  uniformité  visuelle  des  surfaces  et  des  décors,  dont  les  subtilités  et  les  multiples nuances colorées sont désormais lisibles."}],"tag":300},{"ind2":" ","ind1":" ","subfield":[{"code":7,"content":"ba0yba0y"},{"code":"a","content":"This  thesis  is  about  the  study  and  conservation-restoration  of  a  silver  and gilt-silver  pax garnished with a scene of an encrusted enameled Saint George slaying the dragon made from gold and decorated with fine pearls. This very precious object belonged to the religious silverware collection of Baron Adolphe de Rothschild, who bequeathed it to the Louvre Museum before he died, in 1901. The  historical  and  technical  study  of  this  pax  takes  us  for  a  journey  through  the 15th  to  the  19th century in goldsmith\u2019s and enameller\u2019s workshops, from the Holy Roman Empire to France and its world of Parisian collectors. It has been modified in the 19th century to suit the shifting aesthetic taste, thus leading us to the examination of the notion of « authenticity ». Never restored since its entry into the  Louvre  Museum,  this  piece  of  silverware,  which  bears  witness  for  the  great  medieval  Gothic buildings, showed deteriorations which led to uneasy understanding of the scene of Saint George and its decorations. Its composite materials, morphology  and the impossibility of dismantling the central group made it complicated to clean the tarnished surfaces. These issues led us to choose a scientific subject dealing with the electrochemical cleaning of tarnished silver coupled with a stripping reagent. The electrochemical technique was successfully applied to the pax and allowed to bring back visual uniformity to the surfaces and decorations which subtleties and multiple colour shades are now legible."}],"tag":300},{"ind2":0,"ind1":" ","subfield":[{"code":"b","content":"Mémoire de master recherche 2e année"},{"code":"c","content":"Conservation-restauration du patrimoine, spécialité arts du
