Hi All-
We have a fairly new Skutt KM 1027 electric kiln with automatic controller.
We've only fired maybe 6 times, and we're having some problems. We just
did a bisque fire, set to ^04, slow - took about 11 hours and 45 minutes.
We put a cone pack on each of the four shelves. The top one came out
perfect - ^05 slumped, ^04 half-bent, ^03 just starting to bend. The
middle two shelves over-fired: all 3 cones bent more than half-way. On
the bottom shelf, ^05 barely started to bend - it underfired. Has anyone
else experienced this? We loaded the shelves pretty evenly. Should we be
loading differently? Any suggestions or ideas?
Thanks...

I have the same kiln. Here's the advice my dealer gave me. He said if I'm
within 1 cone top to bottom, I'm doing well. He suggested a 10 minute hold
time at the end of the firing to even things out. I found this to work
fine for small to medium size pieces. I have since increased the hold to
45 minutes with larger pieces however. I am firing ^6 porcelain with an
Amaco clear glaze with superb (and consistant) results.
