What's the best way to glue glass "gems" on glass jars or bowls?

There are several ways you can go. If your work stays inside, then Locktite is the best. If it goes outside, then glass glue is the best. Here is a link that will help.

hot gun

Use clear silicone. I've tried E6000 and hot glue. The beads fall off with hot glue and the E6000 works but takes awhile to keep the beads in place.

. Clear Gorilla glue. Works like a charm...just to sure the glass is clean first..

Hot glue gun is the only way I know of, that is how my sister did it with a bowling ball, it came out really nice.

I use silicone adhesive, especially if items will be outside.
