Part 6/7:
With the kiln temperature decreasing to about 920°F, Ryan recognized the implications—widespread heat radiation was still being observed. They decided to turn off the heating elements to allow for a more stable cooling and temperature comparison. As they continued to monitor the cooling process, they were able to gather readings that better reflected empirical data without the interference of actively heated elements.
In their final checks, the Williamson probe's readings fluctuated around 883°F when the elements turned off, and a signal strength of 1.05 suggested an improvement as they closed the kiln door again.
