a screen on a kiln showing the internal thermocouple temperature reading is at 1226 degrees celsius
a screen on the external kiln controller, the thermocouple temperature reading is 1203 degrees celsius
here’s why witness cones can be so important - we’ve had temp discrepancies w internal/external thermocouples on this kiln and i was using a clear glaze which does NOT like going over cone 8 (1260 deg c) so i did not want to accidentally overfire the kiln
