In this paper some of the conservation interventions will be discussed, highlighting how the operations performed are ineffective in slowing down the degradation process, which is the primary purpose of this intervention. the lack of appropriate interventions and the use of unsuitable materials are highlighted. F.ex. the use of pvC binders must be avoided both because they cause pressure on the two glasses and prevent air from circulating inside, favouring condensation and halos, and also because pvC tends to release acid vapours.
