My two worst disasters were caused by gallery people. They were both encaustic paintings on cradled birch panels with no frames around them. One of them, a tiny 5x7 inch piece, suffered a big dent on one coiner that was not repairable. It was one of my favorite paintings, so it is now in my "Permanent Collection"! The gallery who wrecked this one, with which I no longer do business, would not take any responsibility for it. Another one that was 36x48 inches, was taken out of a different gallery without my OK and displayed at another location. It fell off their rickety display and landed on a sculpture which poked a hole all the way through the birch paneling. This gallery which I also no longer work with, took no responsibility for what happened and sheepishly pointed at our contract where it says I had to insure my own pieces. Obviously, I could have sued them for negligence and likely won, despite their insurance clause, but chose not to. Fortunately on this painting due to the nature of the materials, it was a pretty easy fix. I glued a piece of birch paneling fitted perfectly into the opening on the back side and just worked a bit of fresh encaustic paint/wax into the damaged area. The repair on the front was undetectable and will last for many centuries if the painting is well cared for. If you looked closely on the back you might notice that the section in the cradling where the repair was done, is thicker than the others. Other than that it was invisible.
Encaustics are the easiest medium I have ever used when it comes to fixing damage unless it is on the edge or corner of an unframed, cradled panel. If an edge or corner is damaged on a cradled birch panel, the only relatively easy fix that can hide the damage, requires a frame with a deep rabbet. I have dropped a few framed pieces myself but the paintings were not damaged. Fortunately all unframed pieces dropped by me, ended up with no unfixable damage to the painting.
