Zusammenfassung: The treatment of soot-damaged surfaces is a challenging task in the conservation and restoration of artworks due to the properties of soot. This thesis investigates the effectiveness of the polysaccharide gel ´gellan gum´ and its modifications as a cleaning method for such objects. This is done by first examining the history, causes and chemical characteristics of soot damage and analyzing the challenges it poses for conservators. Based on this information, multiple samples are coated with a soot layer to closely emulate naturally occurring soot damage. Various gellan gum gels, some of which have been modified with complexing agents and surfactants, are then applied to the unaged and naturally aged samples in varying concentrations and exposure times. Subsequently, analytical methods such as spectrophotometry are used to determine the effectiveness of the procedure. The results indicate that none of the gels tested are universally effective for various types of soot damage, which warrants further research into specific cleaning methods for soot compositions and aging stages of soot layers.
