E6000 is an industrial-strength glue made from a clear drying, flexible epoxy that works well on wood, metal, glass, ceramics, rubber, vinyl, leather and (most) plastic. It dries very clear, though can form air bubbles if you're trying to use it as a sealant. It can be hard to get the exact perfect amount of glue, and can goop out the side a little if you're trying to glue back together a broken vase.
