I use the Excalibur just fine, only I put a hole in the side for a probe thermometer (Taylor is fine) and baxk overnight at 125-130˚ Fahrenheit, at least 8 hours, and let cool a full day. Works for me every time. About the peeling backing, I have no idea, never happened for me. Someone else might know.

A few of the tapes seem to have sticky shed (unfortunately, I do not know what brand of tape they are, nor exactly how old they are; they are approx.. 30-40 years old). I baked one of the tapes on a pancake at about 133 degrees F for about 4 hours, then let it cool overnight. However, most of the backing peeled off the tape. Some of the magnetized oxide side of the tape flaked off, too (luckily this was a duplicate tape, so it will be ok!). Since this was the result of my experiment, I am thinking that I maybe did something wrong. Also, I was using an Excalibur brand food dehydrator to bake the tape.
