I've had success using a hair dryer. If nothing else, call the 800 # on the bottle, those guys will be able to tell you exactly what to do, I betcha.
Now that I think on it a bit more, if there is a finish or something under the glue, might be able to pop it off with a knife. That has worked for me also, but something nice like one of your frames, I'd call the 800 # before I tried that.
I love the 800 #s, you can learn all sorts of things when you call. Have learned a lot about JB Weld too.

Some days, the supply of available curse words is insufficient to meet my demands.
.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
