Thanks, Mr. Bud and Mr. Wadebevan, your interest pleases me. 
I hope the project approaches its final stage, but without the high temperature sensor I cannot the start the testing because the only reliable information about temperature in the chamber is the moment when steel loses its magnetism. This corresponds to some 1350°F for carbon steel 1060.
The kiln is designed for max. temperature 2350°F, but the working temperature I expect below 2000°F. Hardening of my favourite Sandvik knife steel 12C27 requires 1975°F.
For hardening of alloy steel 52100 temperature of some 1500°F should be sufficient. The temperature of 2000°F should allow forging of 52100 steel.
