This past weekend I fired my gas kiln and noticed that one of the wedge =
bricks in the roof (roman arch kiln) was hanging down and apparently had =
broken. I pushed the brick up, used paperclay to patch around the seams =
and hold the brick up. The patch held beautifully and is incredibly =
strong. I have used paperclay in the past for patching soft bricks in =
the kiln. Just wanted to pass this on. Barbara

Barbara,
What was the clay body in your paper clay?

fiberglass would be a fine toxic substitute for paper which was said
worked fine.

Thanks. What temp? I am wondering if fiberglass would be a good
fiber substitute for brick patching purposes.

I fire to cone 10, but the porcelain patch can probably go higher. I forgot
to mention something. In this particular batch of paperclay, I had added
some ceramic fiber to the mix. However, in the past I've used straight
paperclay (no ceramic fiber) for patching. I accessed the information about
the ceramic fiber from Graham Hay's website. Barbara

Thanks Barbara. This makes sense. A more refractory mix (compared to
a porcelain body) could be mixed for a wood fired kiln. Have
bookmarked Graham's webpage.
Thanks again,

Hi Barbara,
I would not recommend using a porcelain body to repair kiln bricks - too
much flux involved - better to use kaolin and grog - or ground up soft fire
brick instead of grog.
I do think the paper will help but I would recommend you make some up with
kaolin.

At Paragon we are finding that a mixture of powdered
firebrick and kiln cement makes a good patch. Add just
enough cement to hold the powdered firebrick together.
You can obtain the powder from any kiln manufacturer. It is
a byproduct from cutting firebricks.
