adding firebrick to fiber-lined kiln

Well, kind of a bummer, but when I added a sizeable firebrick to the
left side of the kiln and did another test of temperature drop when
shutting the kiln at 968 degrees, there was no discernable difference.
I'm disappointed, but I guess the firebrick additions will not make
enough of a difference. Oh well.

Thanks -- I definitely am going to plan on putting a brick inside on the
left. The right side has the thermocoupler and I'm afraid it will throw off
the controller, but maybe I'm wrong. For some reason, I thought it was not
OK to put anything on the outside, am I wrong?

No. You are correct.

Are you adding insulating firebrick or heavy firebrick? Heavier brick
may make more of a difference.

Check into redundant OT protection. Then you can leave the kiln on for
the complete cycle.
