mending bisque

Hi. I made a female figure type sculptural vase. During the bisque firing,
the breasts blew off. (Looks like there was an air pocket under one of the
breasts and I must have raised the temp too quickly). While I could turn it
into some kind of statement piece about gender identity, or women surviving
breast cancer, I'd rather just stick to my original intent (I call the piece,
"Flower Girl." Ha Ha). I spent quite a lot of time working on it and it's
the only thing like this I've ever done, so I'd really like to fix it if
possible. Does anyone know if I could re-attach the breasts with paper clay
and refire it? I know there was a thread about paper clay on this list not
too long ago, but at the time, I didn't really know what it was so skipped
the messages (the list is so prolific, I have to make decisions not to read
some stuff). Or, maybe I should fire it up to temperature, ^6, and then
attach the breasts with epoxy or something. Any suggestions? Thanks in
advance (I guess that's what TIA means?), Cathie in MD

Kathie Feild,
I have seen a product called "sparset" used to repair broken bisque, which
can then be fired up to cone 10. It is some kind of concrete product---don't
know where to obtain it, but maybe someone else does. But I do know it works.
You can even glaze over it. Good luck---reconstructive surgery is never easy!

Cathie,
I have had good success mending bisque with the following formula:
50 calcined epk
50 100 mesh Kyanite
wet this with a mixture of 1/2 liquid sodium silicate and 1/2 white
(Elmer's type) glue.
work this into a thick yogurt or soft Brie cosistency and apply to both
pieces and attach. This also works to patch cracks in bisque and can be
glazed over. I don't recommend it for functional ware.

Good luck

Linda Stauffer:

To mend bisque: Magic Mender by Marx is a wonderful product, but not
what you really want to add your broken bits back on. Try paper clay.
It really works. You can wet your bisqued pieces, add paper clay,
adhere the pieces back together, let dry, sand, and THEN a) either
rebisque OR b) glaze and fire. For more info and product ordering,
Rosette Gault has a website under paperclay.com.
