Abstract

Herein we present a survey of reported work covering specific applications of liquid and supercritical carbon dioxide (scCO₂) in art conservation. CO₂ has been tested and applied in a wide range of materials, as well as in various steps of a conservation / restoration operation, such as cleaning, protection and consolidation, and it has been demonstrated that CO₂ has a great potential in replacing current conventional conservation processes. In this paper we will present some of the main results published in literature, concerning CO₂ applications for the conservation and restoration of paper, wood, waterlogged, ethnographic materials, stone and textiles.
