But I realized I didn't have a clue what the first test showed me. Pyrometric cones are not straight forward. The point at which a cone bends depends not just on temperature, but ramping speed, and hold time. So after studying the Orton website I choose the my cones.
I'm specifically testing my kiln with a full ramp up to 1550.
|Full ramp, no hold time|
|Full ramp, 30 minutes hold time|
|Full ramp, 1 hour hold|
