Anton Waldt: Possibilities for cleaning soot-damaged varnished surfaces on wood Back
Language: Original   -   Translation
Overview:  
Abstract: Fires are capable of causing hard-to-remove layers of soot on historic varnish surfaces on wooden objects, presenting restorers with object-specific challenges. Within this context, this study compares nine different cleaning media, including dry and wet cleaning media, as well as Nd:YAG laser cleaning. The aim was to use tests to determine which method and under which circumstances soot can be removed as effectively as possible while minimizing damage to the varnish surface. As part of a two-stage test approach, the methods were first tested on sample specimens and then on original veneer fragments from a cabinet from Schloss Fasanerie in Fulda. The efficacy of the methods was assessed using quantitative color and gloss measurements as well as macroscopic and microscopic observations. The results show that none of the methods offers an ideal balance between complete removal and preservation of the original substance. A triammonium citrate agar gel proved to be the most effective, followed by the Nd:YAG laser, but both caused damage to the lacquer surface. Warm water (37 °C) showed the best cleaning effectiveness among the cleaning media that did not damage the surface. The work underscores the need for an object-specific approach and provides an outlook on optimization potential and future research needs.
