Luckily we have a separate kiln room. We usually load in the
afternoons, start the kiln around 7:00 AM, let it fire all day ,
it shuts itself off by 3:00 to 3:30, cools down over night, and
we open it up the next day. It is still hot at that time.
Really be careful about firing overnight, I was told bluntly by
my maintanance supervisor, DO NOT DO THIS.
