Jim,
Cerakote cures at 250F for 2 hours or 300F for 1 hour. There is a thermocoule hanging in the center at feedback to the controller for the two heating elements. Circled here.
I know I am getting 100% cure based on destructive testing of finished parts, that is to say Cerakote is really hard to destroy.
So both of my above scenarios work in terms of time against temp if I understand you correctly.
