The treatment of a longcase clock attributed to Jean-Pierre Latz: alternative approaches to the removal of copper corrosion products on Boulle-style marquetry
A longcase clock attributed to Jean-Pierre Latz from the collection of the Cleveland Museum of Art was treated at the J. Paul Getty Museum in 2012. The clock is dated to 1744 and is decorated with Boulle-style marquetry and elaborate gilt-bronze mounts. As part of the treatment, the tarnished brass...

Paul Getty Museum a restauré en 2012 un régulateur de parquet attribué à Jean-Pierre Latz actuellement dans la collection du Cleveland Museum of Art. Cette horloge à décor de marqueterie Boulle richement ornée de bronzes dorés est datée de 1744. Il était en particulier nécessaire de rendre leur éclat aux parties en laiton, devenues trop ternes en regard de la dorure des bronzes. L’utilisation d’un film de gel pelable appliqué sur une compresse à la colle protéique a démontré son efficacité dans l’élimination des produits de la corrosion du cuivre sur les éléments en laiton, sans altérer la marqueterie et ses gravures. Les recherches menées à cette occasion ont mis en lumière la fragilité de l’écaille de tortue ancienne en présence du milieu chaud et alcalin introduit par la compresse à la colle protéique. Des mesures de précaution ont pu être définies à cet égard. |
