This photograph shows one of the panels from the Drawing Room during cleaning. The upper area of the panel has been cleaned. The cleaning method proved effective for removing both surface grime and excess consolidant that had wicked through the cracked paint surface during the consolidation process. A filling material called Gesso di Bologna was used to compensate for any areas of lost paint. The gesso was sanded to match the level and gradations of the original paint layer before being inpainted to match the surrounding design.
