I've been reading about the topic on the net, and it seems that there are very different opinions on subject.
I was wondering if someone had a more scientific approach to the matter.
Some say that you should open at 130F, and I think that is a little strange because that means that if you make a cup,
you have to mind the temperature of you coffee, and other hot things you may consume of you pottery.
If you open the kiln at 150f and hear crackling, isn't that a coincidence. I mean if the kiln are outside and it is freezing, I see how it might play a role.
