The conservator-restorer is responsible for preserving the artwork for future generations, thereby ensuring the great masters of immortality through the very aspect of their works. Each time the decision to restore them depends solely on their individual need. The restorer’s professional skill is distinguished not only by knowledge of techniques but also the different grasp of every type of style. Restoring is often mistaken for remaking or renovating, instead an appropriate conservation strategy is respectful and intently endeavors to maintain the aesthetics, quality and tactile values asclose as possible to the original. Last, restoration of a canvas or a panel should go beyond the intervention to ensure conservation as well. This means that the restoration aims at slowing downthe deterioration process of the material the object is made of. The criterion of a good restorer’swork should be the reversibility of the material.
