Scientifiques, conservateurs et responsables de mus\u00e9e diss\u00e8quent le monde des contrefa\u00e7ons apr\u00e8s la r\u00e9cente controverse sur la peinture de l’avant-garde russe <\/strong><\/p>\n\n\n\n[\u2026]\n\n\n\n

La science n’est pas suffisante pour d\u00e9couvrir les faux fabriqu\u00e9s \u00e0 des fins criminelles<\/span><\/p>\n\n\n\n[\u2026]\n\n\n\n

\u00ab L’analyse par spectroscopie Raman peut s’av\u00e9rer tr\u00e8s utile dans certains cas pour \u00e9carter une hypoth\u00e8se ou la renforcer, puisqu’elles apportent des donn\u00e9es compl\u00e9mentaires sur la composition mol\u00e9culaire des pigments, charges, liants et vernis mais constituent un r\u00e9sultat partiel qui doit \u00eatre compl\u00e9t\u00e9 et contrast\u00e9 avec d’autres examens pour arriver \u00e0 un diagnostic qui aura besoin de la confirmation des historiens de l’art. Il s’agit d’un travail d’\u00e9quipe \u00bb, a d\u00e9clar\u00e9 Mireia Mestre, chef du d\u00e9partement Restauration et de Conservation du Mus\u00e9e National d’Art Catalan (MNAC).<\/p>\n\n\n\n

La science, bien qu’elle s’av\u00e8re d\u00e9terminante pour \u00e9tendre l’information sur les mat\u00e9riaux d’une \u0153uvre, n’est pas suffisante pour d\u00e9terminer son auteur ou d\u00e9couvrir des falsifications \u00e0 des fins d\u00e9lictueuses. Il existe d’autres possibilit\u00e9s. \u00ab Il est tr\u00e8s fr\u00e9quent que des \u0153uvres d’importants artistes aient \u00e9t\u00e9 copi\u00e9es par leurs contemporains sans aucune mauvaise foi et que des ann\u00e9es plus tard ces copies aient \u00e9t\u00e9 introduites sur le march\u00e9 de l’art, se transformant en falsifications. Dans ce cas l’analyse avec des rayons X et r\u00e9flectographie sont tr\u00e8s utiles, parce que les copies ne pr\u00e9sentent pas le processus cr\u00e9atif pr\u00e9alable sous-jacent, ce que ces examens font appara\u00eetre \u00bb, explique Mestre.<\/p>\n\n\n\n[\u2026]\n\n\n\n

\u00ab En cette p\u00e9riode de crise apparaissent sur le march\u00e9 des \u0153uvres, qui n’ont pratiquement jamais fait partie d’exposition historique. Il peut y avoir des pi\u00e8ces tr\u00e8s int\u00e9ressantes, mais il faut \u00eatre tr\u00e8s prudents et plus encore dans le cas d\u2019une \u00e9poque aussi contest\u00e9e et pol\u00e9mique que l’avant-garde russe \u00bb a d\u00e9clar\u00e9 Rosario Peir\u00f3, responsable des collections du Mus\u00e9e Reina Sofia \u00e0 Madrid. Le Reine est tr\u00e8s prudent au moment d’acheter des \u0153uvres qui ont un pedigree r\u00e9cent et pr\u00e9f\u00e8rent disposer d’une documentation qui se rapporte directement \u00e0 la p\u00e9riode, au-del\u00e0 du mat\u00e9riaux, puisque sur le march\u00e9 noir, on peut acqu\u00e9rir des toiles, des pigments et m\u00eame des brosses de n’importe quelle \u00e9poque.<\/p>\n\n\n\n
