I recently had new kitchen cabinets installed. I used some very nice
pulls, frosted glass with brass bases. Everyone who comes over and opens a
cabinet seems to linger their fingers over the pulls, remarking that they
feel so nice.
The problem is that some of the glass parts have pulled free of the brass
bases. I repaired some using epoxy, but they don't seem to hold up. I put
one in my pocket yesterday to take to Lowes to see if they still carried
them (they don't) and it broke. Pulled the glass right off the knob! This
made me wonder if the reason they aren't holding up is that the epoxy is
shrinking (or maybe expanding) during curing and stressing the glass so
that any little bump breaks it. I know that hide glue was used for this
property to make some types of decorated plate glass. You paint on the
glue and as it dries, it shrinks and pulls a bit of glass from the surface.
Does epoxy change size during curing? And if so, is there another option
for gluing glass to brass for my knobs? It looks like it's going to be
near impossible to get more knobs, and I don't really want to replace all
of the kitchen knobs after only 2 years, so I'm eager to find a repair
option.

Yes, epoxy does shrink a little as it cures. I believe you'll find most
glues will as they give up whatever it is that makes them runny.
Perhaps you could use something that remains slightly flexible.
Silicone adhesive comes to mind or 3M 5200 which is waterproof marine
sealant. It is hard to release if you ever want to. 5200 is white,
though and this might be a problem if any of it would show.
g'luck.

Epoxy ? I bet it's coming off the brass, not the glass.
Try a polyurethane, like one of the Sikkaflexs
John - I can only speak to one epoxy because it's all I use - West System.
I've used it on boats to fill bolt holes (mixed with micorblaoons) and to
epoxy in where I've replaced bad wood. I've never seen this stuff shrink at
all.

Epoxy will shrink, but there are different types, you'd have to experiment.
Without seeing what you're talking about, it's difficult to see how to fix.
I might suggest the Gorilla Glue I thinks a polyurethane type glue, you
activate it with a little water and it will expand so use it sparingly, but
the shit is tough!

Epoxy may or not shrink, but it definitely does not expand with temperature
like brass. Using eposy for this application is a big mistake.

Mine, either. (Right, Steve?) ;)

Forget epoxy, it won't do the job.
You need an adhesive like 3M-5200 or SikaFlex292.
5200 is available in small tubes at marine chandleries like West Marine.
Home Depot also has 10.5 Oz, caulking cartridges but that sounds like
way too much.
Putty the glass back onto the brass and let cure at least a week, then
reinstall.
5200 is a PITA to work with, but you can't beat it for a job like this.
Wear throw away gloves or you will be sorry.

Yep. Epoxy and brass just don't play well together - at least in my
experience.
