Analisi critica di metodologie tradizionali nel restauro di dipinti murali

In recognizing the significance of the extraordinary results achieved in the testing of materials and innovative technologies in the field of restoration this paper wants to focus on the importance of a closer examination of the effectiveness of traditional methods and materials as a starting point for a more informed interventive conservation. We describe below the cases of some treatments where the characteristics of procedural choices adopted in previous restorations have been approached and verified: a critical analysis of the maintenance procedures executed in the past has allowed to discern the operative solutions and the materials still efficient and to present them again with few corrections avoiding an uncritical, common use of new products that are sometimes very invasive. This study compares the methods of extrados strengthening and of tying of the light vaults and of the detached plaster in use from the seventeenth century until the middle of last century.
