what kind of kiln do you have? Every kiln is different, even among similar make and model. The thing is, your cabs didn't look over or underfired. I don't think overfiring is causing your problem.

What I meant to say was that only you will know what schedule works best with your kiln and the pieces you are making. Keep a notebook and record schedules as well as comments about the outcomes. You will know what works best by doing that.
