What glue to use

[Halfathumb]

I'm trying to glue on a ceramic knob to a glass butter dish. I've used epoxy but it failed in a relatively short period of time.

Any suggestions for a better glue or another type of knob that adheres to glass?

I have 2P 10 that I'm considering using.

E-6000 is designed to glue non-porous to non-porous surfaces.  It is like silicon adhesive on steroids.  It is widely used in the cheap gemstone jewelry business to glue glass "gemstones" to  metal findings.

It is a styrene based adhesive, and like silicone adhesive it remains slightly flexible. 

If you are gluing a large surface, then make long beads of adhesive.  The glue requires air to cure.  If you close off all the air only the  perimeter will cure.

You can find it at Lowes and most hobby stores and amazon.com.

are you sure it was the epoxy that failed? Maybe there was some contamination on one or the other or the pieces to be glued.

I cleaned both surfaces thoroughly. I think it failed because both surfaces are so smooth

You could drill a hole in the glass cover and use a mechanical fastener.  You will need a special bit for that and I have had better luck using a Dremel bit:

I don't think I should experiment drilling a hole in this butter dish, plus LOML said "NO". I'm an obedient servant.

I've drilled glass doors for knobs using a special bit used for glass. The bit looks like a spade bit as it is flat. No point , shaped some what like an oval or a spear. Hardware stores and box stores will carry them. I use a drill press when possible and kerosene for a lubricant.
Place a piece of thick cardboard on the table. Next tape a piece of shirt cardboard or similar over the drill spot. You only need a small square of this cardboard. The bit wants to skate over glass and the cardboard helps to alleviate this. If the hole is small, less than 3/8" then drill slowly  til you score the glass, then stop and remove the cardboard. Keep drilling slowly and paint a lubricant on the bit. I use kerosene but I think almost any lubricant will do. Only drill til the bit penetrates the other side. Stop, turn the glass over and finish drilling.
To be safe, when done drilling , loosen the chuck and let the bit slide out. The bit will fall out as you lift the glass off the table.
If you have to drill larger holes, make a dam from clay or plumbers putty. The dam is filled with a lubricant. 
Practice on a scrap piece of glass. Your trash can has jars or something made of glass to practice on. 
Wear eye and hand protection to be safe.

If you have a Dremel, you can grind a hole.

Cooler; Thanks for the link. I'm not going to get a Dremel thill I'm sure I'll have other uses for it. What other applications in ww do you use it?

I was thinking about the glue they use to glue rear view mirrors on cars.
