broken bisqued rim

I just bisqued fired a very large bowl with an elaborate rim. Part of the lower rim decoration broke off. Is there any way that I can re-attach it before I glaze fire it? I would appreciate any suggestions.

Dear Ronnie Breezer,
Fire the shard unglazed but glaze the pot except for the fractured
surface. Put wax resist on that before you apply the glaze.
Then use the shard to effect a repair but make sure you put an
interfacing of Carat Gold leaf across the fractured surface to
emphasise the union. If you wish to get greater contrast, blackfire
the shard. Use a super glue or Araldite as your adhesive.
Best regards,

Try using paper clay slip to "glue" the broken piece back onto the body and
then bisque fire again. You can glaze and fire normally afterwards. This
has worked for me. Be sure and make your slip from the same clay body.

An additional step that has worked well for me. Got the tip from either
Clayart or one of the magazines, add some powdered bisque of the same cla=
y
to the paper slip.

I didn't see the original post, but I have
some success using Amaco's majolica
gloss under glazes on the broken surface
of both the pot and the part that is to be
attached - and then do a bisque firing.=20
That assumes that you can get a good=20
fit for that bisque. After the firing, you
can use a bonding agent to fill in the cracks,=20
and then put an underglaze over the whole=20
area and either rebisque and then glaze fire
or try your luck with a glaze firing at that=20
point. If it is not an important or time=20

to repair it than to just make another.
