Brandsläckningspulver och oljemålningar på duk -En intervjustudie om tillämpliga rengöringsmetoder

Abstract

In the autumn of 2018 during my internship I was cleaning a painting that had been exposed to fire. Beside the damage caused by fire and the degradation caused by age the painting was also covered in powder from a fire extinguisher. In contact with water the residue from the extinguisher turned into a soapy film over the paint layers. This soapy film was difficult to remove and had to be removed with wet cleaning methods. However the solvents used for removing the residue could also have a risk of transporting the residue even further into the paintlayers. When working with the painting I was looking for literature discussing how other conservators had dealt with this kind of cleaning and I realized there was quite a few literature discussing this matter. This realisation led to this bachelor thesis which goal is understand what kind of impact fire extinguishers may have on paintings and which methods that are used by other conservators in order to remove residue. In order to reach this goal a literature study was first carried out. Thereafter, interviews was made with professional paintings conservators. The conservators answered a set of made questions in order to explained their encounters with paintings covered in extinguisher residue. The result was then summarized and used in a final discussion.
