- Résumé
- Support for aged and deteriorating paintings has historically been provided by lining the painting with various adhesives and canvas; however, the introduced stresses and the reversibility of such a treatment is now better understood and approached with greater caution. Alternatively, a painting can be loose-lined with a solid support, such as Gatorfoam, without the use of adhesive. Gatorfoam is an inert polystyrene laminate board used in the field of conservation. Applied as a backing between the stretcher and the canvas, such a preparation would provide a stable support on which the painting can rest, reduce vibrations due to handling, and reduce the effects of varying humidity and temperature. Stiff lining supports have been shown to improve the ability of a painting to withstand deterioration factors and a backing would reduce exposure of the canvas, the most responsive element of a painting. Furthermore, the treatment is easily reversed with minimal stress on the painting. The application of Gatorfoam between the stretcher and the canvas is an invasive treatment, but justifiable in some circumstances. The qualities of the Gatorfoam backing treatment were compared with the routine practice of attaching a Coroplast sheet backing to the reverse of the painting structure, which offers similar benefits of reduced vibration during transport and decrease in the effects of fluctuating relative humidity and temperature. Sample paintings were prepared with a brittle surface coating in which natural cracking patterns developed. Coroplast backing boards were applied to one group of three canvases, Gatorfoam backing boards were applied to a second group of three canvases and the third group of three canvases remained untreated as a control. All sets of the canvases were cycled through extremes of relative humidity and were documented before, during and after the period of cycling. The success of a Gatorfoam backing to improve the longevity of a fragile painting was evaluated, although Reflectance Transform Imaging photography and subsequent image processing were not able to resolve the crack patterns in a way which facilitated comparison.
