Emission Systems For Cars And Trucks Cheapest Parts On the Web

I have three decorative knobs on my bathroom cabinets. The part that fastens to the cabinet doors is metal. The decorative part is glass. The glass part seats in a recess in the metal part.

Recently, one of the cabinet doors was stuck and a family member pulled the knob too hard and the glass separated from the metal. After I fixed the door (I trimmed one end), I glued the glass and metal together--twice!--and each time it lasted no more than a day.

I haven't tried any epoxies yet, but I tried one glue (I forget its name) and, since I had it lying around the house, the "all glass" Super Glue (Super Glue's website seems to indicate that this is best for "glass on metal" too, and I can't tell if they even make a "glass on metal" glue or epoxy).

Can you suggest something that you think would work? Thanks so very much.
