Is it necessary to be home the whole time the kiln is running? Can I run it when I'm asleep?

We recommend that you fire the kiln while you are home, especially toward the end of the firing. You can program a delayed fire on digital kilns so that the kiln starts at a time that will suit your schedule. You can fire the kiln at night, but you should set your alarm to wake you up near the end of the firing. The kiln should always be monitored especially before the expected shut-off time.
