e6000 glue is the ultimate glue, everybody looking for this e6000 glue.
E6000 is used to attach jewelry findings to your glass. Jewelry findings can be bails, ear wires, jump rings, or whatever you are trying to attach. The large tube will go a long way, as you only need a little of the adhesive to secure the piece.
Put a small amount of E6000 on the piece. Use enough glue so that some of it squeezes out from under the bail. This will form a nice lock around your finding. Use firm pressure as it is pressed it down. Clean up any adhesive that might have spilled elsewhere on your glass.
You can find that e6000 glue at online store easily, but local shop near you maybe doesn't have this power glue.
