I have never used E6000. I use GE silicone ll clear adhesive window/door/attic/basement. I also want to make hobbit and fairy houses with old bird houses or whatever I can find. Do you have any pictures to share? I have made glass flowers, glass sun catchers, and glass totems using the silicone adhesive. I have left a lot of them outside this winter and so far they are all holding up great in this years Iowa winter.
