ABSTRACT
In the recent years, according to a large number of conservation reports (Scherer 2009, Ziegenbalg 2008, Bracci 2008), stone consolidation has achieved good development and most of the new techniques have been applied to the field of heritage conservation, always according to the principle of protection with “minimum human intervention” and “no changes” in the historic condition. The treatment must be reversible, ensure the maximum durability and invert the degradation processes without changing the chemical and physical properties of the material (Agnew 2002).
