@rundocuri- It sounds like epoxy glue is the type you need. It definitely holds better than most types of glues, and is especially good for hard-to-glue materials like glass and metal.
Epoxy is easy to use, though it is important to keep in mind that most types dry very quickly. Once you thoroughly mix equal amounts of both the hardener and the resin, you only have one or two minutes before the bond begins to form. This is why you will need to have the items that you want to glue ready as soon as you mix the epoxy.
Another thing to consider when using epoxy is that it will be very difficult to remove from your skin if you get some on it. Be very careful with the mixed epoxy, or better yet, wear a pair of thin latex or cotton gloves while you work with this type of glue.
