I'm in a bind with this jar. I found it in the woods like this, with contents still inside. I don't know what is in it. Maybe apple butter? Anyhow, the lid is completely stuck. Nothing I've tried has worked. I'm about ready to get a Dremel tool and cut the lid off. But there's risk in damaging the jar. I know these aren't worth a lot. But it would be nice to have it to go with the larger 28 ounce har I have. Does anyone have ideas on how to unfreeze the lid?
