Power outage near the end of firing

Recommended Posts

So, yesterday afternoon the power went out while the kiln was bisque firing. I saw the temp when it was over 1600, on the way to ^06. I see today the ^07 has not moved, but I think it probably stopped at about ^08, so I think I can adjust to that. My question is about the clay gases releasing, because the vent stopped when the kiln stopped. The kiln was closed and unvented until early this morning when I was able to restart the vent. Do you think there is a problem with the clay not being vented on the decline temps. Any thoughts? Thank you!

The power outage was widespread. Maybe re-fire on faster schedule since it is basically already cooked.

With further reading, I see that carbonaceous materials burn out between 500°F–1450°, which leads me to believe that if the pieces are hard enough, the impurities should be burned out and the clay should be ok for glazing.

Glaze it up and move on.
