Re-firing

[dooarts]

Can re-firing (cone 5) solve a drip problem on the interior of a piece?

[Bill Kielb]

Anything is possible but refires for me rarely work out as the glaze and clay have transformed themselves in the first firing. That said, if you have nothing to lose ...... I occasionally have fixed something using lowfire glaze (cone04) when an aesthetic issue. I am assuming this is a cone six fired ware.

In my experience, I have found that re-firing will probably change the characteristics of the glaze outcome unless the glaze is pretty basic. Here are a couple of pix of a bowl that had a defect which I tried to repair. The second firing caused other problems, but you can see where the glaze is different in the 2nd firing.

It depends on the piece. Some clays and glazes take better to re-firing than others. Some glazes look better after they’ve been re-fired, some don’t. Some clays will bloat with re-firing, some you can fire multiple times with no trouble.

i refire more often than others might.  if there are several pieces i use a cone lower firing and that usually works.    read "usually" as not always.   sometimes i think it is placement in the kiln.  use cool spot if you have one.

I recall a "cup" piece by Ron Nagle that was glazed fired ~25 times.  

It depends on the firing temperature, the glazes, the clay body, and the heating & cooling rates, and sometimes the amount of cream in your neighbor's coffee two days after the firing.

When I see really radical glazes from gallery/ museum  potters  i.e. Brother Thomas, Chun Wen Wang,  I always suspect multiple firings.
