Nancy Moskovitz asked in a comment about my framing of pastels against the glass. The largest painting I have done that way is 16 x 20 inches on board. Most are smaller. We (Gene and I) have been doing it for about three years I think. I have heard of several artists that do it and have not heard them say anything bad that happened. Some information I found online against it say that the artwork may stick to the glass and become moldy. I think that could happen with mats and spacers as well. The artwork could stick to the backing or mats. If it is going to happen, won't it just happen? If the glass breaks, the pastel is likely to be damaged in either case. We tape the boards, Pastelbord or mounted paper to the glass with clear artists tape.
Here are some pros:
- If the pastel is taped to the glass, no pastel dust is going to fall or be attracted to the glass to cause cloudiness.
- We put a foamcore backing, sealed with artists tape on the back. I use standard size frames so if the purchaser wants to change frames, they can heat the tape on the back, remove the backing, take out the sealed painting and glass and put it in another frame.
- Framing is easier, no pastel falling on the mat.
- No paintings coming loose from the mat and sliding down and damaging the painting.
- Less warping with no space in between the painting and glass.
We have not used this system with paper that isn't mounted. If I use paper, Gene cuts it to fit the frame and I mark the mat size on it and then the painting does not have to hang on the mat or backing. I think with a good backing this would work and not wrinkle anymore than a hanging piece. I still put a spacer at the bottom part of the mat to catch the pastel dust. I'm sure this is another no-no, but I had several paintings come loose from the mats in this hot weather in Texas that had to be framed again.
So lets hear from you and see if these methods are more accepted "these days" or if we should be doing it the way it has always been done.
