Our paintings conservator has worked on some challenging projects! This painting is a nineteenth century American landscape that has suffered multiple tears in the course of its lifetime, probably due to the poor quality of the canvas. (It’s not in the CAM collection.) The canvas is thin and woven of fine fibers, but the weave itself is very irregular, with a loose open weave in some areas, and tighter, more closely packed threads in others. This, along with a tendency toward brittleness, has meant that the canvas supporting the paint layers is very prone to tears.
The back shows at least four, and possibly five, separate applications of different adhesives and patches. The most recent and maybe most drastic intervention is shown here. Someone stripped off all the patches on the back and glued the canvas to 1/8” Masonite™ board using a white craft glue. The glue was not spread evenly, and water in the aqueous glue caused the canvas to swell unevenly as well, so there were large loose blisters of canvas throughout.
Both the Masonite™ and the glue are much stronger than the canvas, so unfortunately there was only way to remove the painting safely. A layer of tissue paper was glued to the face of the painting using a conservation adhesive for protection, and the painting placed face down on a sheet of plastic. The Masonite™ was then carefully shaved away in layers, using scalpels and knives. As shown here, much of this work was done under the microscope in order to ensure the canvas was not damaged any further. While tedious, the removal always needed to be performed with painstaking attention. (This is one of those conservation procedures that calls on every bit of patience a conservator can muster.)
Once the board and remnants of adhesives are removed from the back of the painting, it will be lined to a new canvas support and stretched on a stretcher, a presentation much more in keeping with its original oil-on-canvas structure.
