Good for you, wish I could say the same thing lol! I've got 10 deeps and a 100 frames to put together, too bloody cold up here yet. I can get the pole barn warm enough to work, but I don't trust the glue to set right.
You'd be better off putting it in an inside pant or jacket pocket. Let your body warm it.If you must use the burner put in in a pan of water. Let the water heat in the pan and then drop the bottle of wood glue in.
