This is a firing schedule that I maintain in our group account at Insight-live. We have three electric kilns, each with thermocouples in various states of decay. How do I get the accurate firings I need for test bars? First, I program the steps of all our firings on the controllers. Second, when unloading a firing I note the position of the cones and the temperature the controller was programmed to go to. From that I extrapolate (by experience) what temperature I need to program to next time to get it perfect. I am doing this for a dozen different cones on three kilns.
