Phil...
 I have has success using an epoxie compound thaty had a copper substance
in it for continuity.
In fact as I recall Ford Motor made (or marketed) the product for precisly
this application. I doubt you
Will ever get the glass hot enough to melt the solder. Too much of a heat
sink. I haven't looked for the product recently but it may also be
available from the mass marketers.
 Good Luck

Subject: rear-window defroster-connection

Well, while waiting for some qlist BTDTs regarding resoldering a detached
electrical connector to the edge of the rear window (gulp, it happened to
the connector for the ground wire--on the right edge), I asked around
locally. One auto glass repair guy said he doesn't try to do it "any more"
because sometimes the window cracks (just replace the glass, he glibly
advised). An Audi repair shop claimed to have some limited success doing
the resoldering, but that their failures were not because the glass cracked
(just bad solder-joints, I guess).

So I'm inclined to give it a try myself in the near future (oh yeh, I'd
best  get my ohmmeter out first and verify that there is good continuity
from the power connctor all the way to the ground connection point.)

I have a 120W soldering gun and a 45W iron. Will probably use silver
solder, which I assume will require low(est) heat. I think the 45 watt iron
would be adequate (and safer), considering that the metal spade-connector
is quite small and the glass is not a great heat conductor. Any words of
warning or encouragement?
