Principii de restaurare clasice și contemporane. Rămâne reversibilitatea o regulă de aur în teoria contemporană a restaurării?
Contemporary and classical restoration principles. Is reversibility stil a “golden rule” in the contemporary tehory of restoration?

Summary/Abstract: Reversibility has been one of the main principles of the ethics and practice of restoration, a declared ideal which has never been achieved in practice. It was argued from both scientific and restoration practice perspectives that it is impossible to achieve a complete reversibility. In this context new alternative notions were formulated, such as “removability” or “retreatability”. It was also proposed to discuss about this principle in terms of degrees of reversibility. By formulating and defining new notions such as “technical reversibility”, “visual reversibility” and “reversibility of the aesthetic effect”, the concept gained new theoretical dimensions.The analysis of “reversibility” was proposed to be undertaken for each phase of the restoration process. In the case of cleaning treatments for example, the issue was discussed in terms of reversibility versus controllability and selectivity. Also, problematizing the consolidation treatments, it was suggested the replacement of the term ”reversibility” with the notion “re-treatability” which implies two essential concepts: durability and physico-chemical stability.Some authors consider that the principle of reversibility is still a very important norm, while others discuss the replacement of the term with more appropriate ones. Piero Baglioni has launched the idea that durability and physico-chemical compatibility could be considered a new “golden rule” of the contemporary theory of conservation, while Christina Margariti firmly states that the reversibility concept has already been replaced with the notion of re-treatability.
