I just opened my kiln after doing a bisque fire. Two of the sculptural
pieces lost a few small parts. Is there anything I can use to re-attach
the pieces so I can glaze fire them? I've heard something about "magic
mender" I have a big show coming up on the 14 and don't have time to
remake these pieces!!! Any advice would be appreciated.

Hi Linda,

On an earlier post from mel jacobson, he mentioned using a product called
Trowleze, an air-setting, high temp. bonding mortar made by National
Refractories and Minerals, for just such situations. I found it at
Continental Clay in Minneapolis, MN--but I'm sure other pottery suppliers
either carry it--or something similar. It's worked extremely well for me
for bisque repair and I also used it to replace a bad element holder in my
L & L Kiln.

Regards,

Hi Linda,

One thing to do is to "glue" them together with "magic mender" and then
rebisque them before glaze firing. Or you can glaze and fire the pieces
separately, then epoxy them onto the piece and touch up the connections with
enamels (Testors hobby enamels look like glaze), but you may have to fill in
the "seams" with epoxy paste (PC-11) first. Magic mender has worked pretty
well for me (not always), but do it carefully -- you can sand off excess after
firing.
Hope this helps.

Linda,

it may be too early to say for certain, but I have used paper slip to reattach a
broken bisque piece for one of my students. She couldn't face loosing the piece
and there wasn't time to redo it, so...

I took a small cup full of slip made from our clay body. Then I took a cup full
of water and added a large handfull of toilet paper (yep, straight from the roll
in the restroom). Wet the paper in the water and mixed to a pulp with a
mixer/blender. Then, I added the paper pulp to the clay slip, about half and
half. Mixed thoroughly.

Soak the two areas that need to be mended in water for a minute of two. Brushed
the edges of both bisqued pieces with this paper slip. Added a small coil of
fresh clay and stuck them together. Covered the mend with a coat of the paper
slip on both sides (inside and out).

Bisque fired the piece again and the mend seems to be holding. The trick is
just to get the glaze on without breaking it off again (I doubt it is a strong
bond). But once the glaze melts over it it should be fairly well attached. We
are glazing and firing next week, so I don't know for sure how it works, but so
far so good.

the archie bray foundation sells a bisque patch material
but I will let you in on the secret

it is fiberfax cement

works great
the only problem is that the cement is real refractory so if you glaze over it
you get this white line

Linda,
I have had some luck with a material known as Cera-Fix. When I was
teaching at a local HS my supplier had invented this stuff. Like anything
you will have to try it and see if it works for you. My opinion is if it is
broken it will never be the same, and it is hard to find something that will
really be strong, but sometimes there is no choice and it is easier than
reconstructing the whole piece. I believe he has a web page listed at the
Ceramics Web in the links section as Botega Industries. It is located where
I live in Palmdale, CA. If it doesn't work please don't hold me responsible.
I think his number is 805-947-3516 ask for Les Kinzel, tell him Craig sent
you.
Good Luck,
Craig

Try paper clay & rebisque. It works! Lana R.

Linda:

I had wonderful results with mending goblet stems that had popped off
during the bisque fire by mixing elmer's glue, powdered glaze (that
matured at the same temp of the glaze fire) and paper clay. I used the
concoction to adhere the pieces together, then applied additional
paper clay over the joining cracks. The results were unbelievable. You
couldn't even see the cracks because the paper clay had bridged the
gaps.

Hope this helps...

Linda:

I failed to explain why my technique worked.... After the concoction
dried, the Elmer's glue held the pieces together while I glazed the
goblets.... (and later burned out) the paper clay helped bond the
pieces, and the powdered glaze melted in the subsequent firing and
internally bonded the pieces permanently. The paper clay made a smooth
covering over the cracks so they didn't show thru the final glaze.
Like I said, the results were that you couldn't tell the pieces had
ever been apart.

Good luck.

Tena
