04 pyrometric cone broke rather than bend?

Recommended Posts

Is that an issue? I fired my baby Olympic kiln for the first time (bisque). Just had one mishap were I turned the dial the wrong way (off instead of upping it to medium) so it was off instead of on medium for an hour. It shut off within the window the manual gave...but noticed the cone broke instead of bending? Thanks from the newb!

Sometimes the mini cones have an unseen fault that causes them to break rather than bend smoothly. When that happens, it might turn the kiln off right then, or it might jam in the sitter mechanism and the kiln keeps firing. And firing. And firing... Always set the timer (if there is one) to slightly longer than anticipated (so it will turn the kiln off before too long if the cone fails), and be there when the firing is expected to end and turn it off when the witness cones in the kiln indicate it is done.
