- Résumé
- This study was proposed by Anne-Stéphanie Etienne and Eric Hagan at the Canadian Conservation Institute to contribute toward their larger research on the lightfastness of wood and developing a system to improve wood fill treatment. This study specifically selected hard woods that could be used as fills for mahogany objects and determined their lightfastness by artificially aging samples and measuring their subsequent colour change. All woods were uncoated, with the exception of one sample which was finished with a pigmented shellac coating. Samples were aged in the Q-SUN Xenon Test Chamber at Queen’s University for 504 hours. Colour changes were measured with the Spectrophotometer CM 700d using the CIE L*a*b* colour system. All samples were found to lighten over time, with light-to-orange woods experiencing the smallest overall colour changes and the earliest plateaus in colour change. None of the dark woods sampled here reached a plateau during this experiment; however, several of the dark woods were found to be the most lightfast. The best performing sample was the finished African mahogany. It was both the most lightfast and the most resilient to colour change. These results aide in the larger goal of determining feasibility of using different aged or ‘pre-faded’ woods as gap filling materials.
