Taking it to mean that you are writing about sealing the voids between
the lead came and the glass, you will be forever doing it using
regular glazing compound if you are trying to neatly stuff it in the
cracks one-by-one. Take a look at
http://www.inlandcraft.com/howto/page24.htm and see if this looks more
practical. There are several different brands of cement available from
your friendly local "stained glass" studio but the method is similar
for any of them. This is roughly the method I learned in a leaded
glass class I took: manually smear regular glazing compound over the
panel's seams and use a stiff brush to force it into the cracks and
then use the whiting and another brush to scrub everything clean.


John, after re-reading the web page above, and looking at the window
again, it is clear to me that cement was used initially. Unfortunately,

May be hardened putty. Here is a good "how-to":

the windows were installed by nailing in a nail flange (I hope I used the
right term for the sheet metal that goes around a window and then nailed
to the wood), then the nail flange was covered with brick. The only way I
can see to remove the windows is to remove the brick around the window
and pull the nails out, or cut the window out with a saws-all. Neither of
these options is going to happen grin.

A question for you though, can I use the stained glass cement in a very
thick mixture to brush it into the cracks? After it dries, what would you
suggest I use to clean the windows to get the cement residue off, and
make the joints look clean.

Thanks.
