Please read carefully the instructions and information
on the Patch Attach. I seem to remember students
using it occasionally, but that it was made for low
temp firing. Make sure it will withstand temps in
wood fire kiln.
You might do better to make a paper clay slip and
attach with that, and then re-bisque before the
wood firing.

I have used high fire mortar on things where the glaze will cover it after
it has been bisqued again.
For example, animal sculptures that will be glazed with copper matte and
rakued....It is groggy and turns a pale terra cotta color when bisqued.
It has to be bisqued before you can glaze it.
I have also used paper clay.

Noelle,
Should your piece not make it through the
firing all may not be lost.
I've used waterproof Epoxy Putty. I have
mixed mason stain into it to get a color match.
I get it at Ace Hardware.

I don't know what patch attach is.
What I would have done is snap off the loose arm. Dampen it and
reattach with a paper clay slip of the same clay body.
Then re bisque it. This usually holds for me. Then fire as desired.
A paper clay patching slip is using toilet paper dissolved overnight.
dry powder of clay body, a dash of corn syrup and vinegar. Another
dash of sodium silicate adds a little flavor. Dashes vary according
to volume of patch being mixed. I mix this concoction in a blender
and store in a plastic container.
