JD18-JH Update: 15th Firing Test
I’ve currently performed seventeen ^11-12 firings with my new kiln, and the elements look and read great, showing no signs of getting tired.
After my 15th firing, I did a test run by programming a 350deg/hr. rise to Cone 9. The kiln managed the programmed ramp to the calculated temperature –no problem.
*As a reference, with my older kiln using the standard run of holders, I was averaging 25-30 high-temperature firings, and noticed signs of element fatigue by my 15th firing. Keep in mind, that I’m doing some pretty harsh firings, so others may get better life.
But an extreme test is often the best test.
