Have you ever had an over-fire because the shelf was too close to the
Kiln Sitter tube, and the shelf expanded and interfered with the
bending of the cone?

No, I've never over fired because the shelf expanded. I once over fired a
bisque load because I didn't watch the placement of the shelf in the kiln
and it was positioned right next to the sitter. When the little cone in
the sitter melted, bent, the kiln sitter tripped, it got caught on the
shelf and the kiln switch didn't fall or shut off. The kiln kept firing
and by the time I figured it out (no timer on this kiln, and no
controller either) I had something like ^6 unfired pots. I still have a
few of those pots, and consider the whole experience part of my
education. Usually, an education ends up costing and it's usually not
I think it's a corollary of Murphy's Law that a kiln shelf ends up right
at the level of the sitter.
