Environment and biota safeguard in the cultural heritage field

Abstract

In the past the unsuitable choices made when choosing products to be used for conservation actions related to artefacts of historic-artistic interest were mainly due to wrong assessments. More specifically this means: insufficient determination of the structure-aspect relation which characterises the original materials that make up the artefacts; insufficient knowledge of the behaviour of new materials due to natural ageing processes which might impoverish them or deprive them of specific qualities; lack of interest in measuring the medium-long term effects and interactions of the artefacts-products-environment system. The latter is sometimes capable of triggering new and more serious factors leading to the deterioration of the artefact sometimes causing even greater damage. In particular this study refers to the aspects related to the potential danger deriving from products used for the different types of conservation interventions on stone materials.
