Thanks for looking.  Here are 4 shots of the crystal.  The question is - can
this be glued?  I went to the local (rural town) glass shop and they said they
were not aware of “glass glue” but they had an epoxy they used to glue metal
parts to glass.  Text at the bottom of each shot:

There are several glues listed for glass - pretty inexpensive in a small tube.
Anybody have experience -  I don't want this to come apart as the table below is
glass and I already put a tiny chip in it with this “incident"

Ed,

To be successful in sticking the pieces together AND doing it imperceptibly
you'll need to find a glue that matches or approximates the refractive index of
the crystal. Crystal is usually "lead glass", and I *assume* most have a
*similar* index of refraction. Hopefully the glues you're researching will say
something about that.

Good thought.  The chandelier is a random sort of jumble, so I don’t know that
it will ever be noticed, but I will look for that.

  Here's what I did when faced with the same situation.
  I used the UV glue and its been holding 15 years or more
  http://users.snowcrest.net/kitty/sgrandstaff/images/house/crystal.jpg
  Having more glueline is why I think it held.

  But I also have some pretty similar crystals stashed somewhere. I will 
dig if an exact match is not mandatory?

You'll be wishing it was a white linen table cloth.

I've tried to glue glass, and the frustration level was pretty high.

If you want to glue, and the glass shop has no clue, you might do well with UV
curing gel. The local nail salon will have this, and the light to cure it, too.

I believe it is a generally a UV polymerized methyl-acrylate. The clearcoat gel
is actually what the repair tech used last time I had a chipped windscreen. Yes,
it really was the nail polish prep. As good a match as the previous repair with
the windshield specific stuff-- not perfect, but not very noticeable. The nail
gel cures with UV-A, wavelengths in the ballpark of 360 to 400nm (near visible
UV-A to the shortest visible blue), which, conveniently enough, most glasses are
fairly transparent to.

What is the worst result? It doesn't do it and you need to soak the thing in
acetone for a while to clean it and start over?
Cleaning/prep would be acetone and light brush for loose debris.

Great idea.  

One of the more sophisticated guitar repair shops does something similar.  The
nut is the part of the guitar up near the tuning machines that the strings pass
over onto the fretboard. The depth of the nut slots is pretty critical to how
the guitar plays, and if you get them too deep, then you start over as there has
been no quick, permanent fix.  These guys pioneered the use of dentist teeth
filling material with the UV light to fill in the too-deep slot and then start
over.

Never thought I would say this, but “of to the nail salon, honey”

It's fairly common, in a big antique centre (multi dealer type)
that "someone" will have a bowl full of chandelier bits, at least here
in the UK.

"If you want to glue, and the glass shop has no clue, you might do well with UV
curing gel. The local nail salon will have this, and the light to cure it,
too.....What is the worst result? It doesn't do it and you need to soak the

Well, no.  The worst result would be that continued exposure to UV would cause
the adhesive to crosslink, becoming insoluble and irreversible, and also
changing the color of the glue line to something glaringly apparent. Or
continued exposure to UV (or just additional time to allow reactions to go to
completion) could cause the glue line to become weak and brittle, allowing the
crystal to drop off in response to a little jar, knocking another divot out of
the table underneath. And, if I remember correctly, sometimes you can get both
weakness/brittleness and irreversability/insolubility in the same repair, for
that little fillip of ironic bitterness.

Thirty years ago, when I was young and enthusiastic, I paid attention to a wide
range of conservation literature, and to the best of my memory these were all
problems commonly encountered with the first generation of new "permanent "
adhesives that had been accepted by the early conservators. I don't know the
current state of play, but if you decide to go with glass adhesives on the
original crystal, then research very thoroughly, and do the research in recent
professional conservation literature, not in hobby or do-it-yourself sources,
not in thinly disguised manufacturer's hype. I'm not saying that adhesives are
the wrong way to go, because I am decades behind on developments. But myinstinct
is that it would be better to drill a new hole in the old crystal, or get an
entirely new crystal.
