Thanks All.
I suck at trying to see colors in "glowing" metal. I cheated and modified an Aim glass/pottery kiln with a digital controller for heat treating & tempering. Furnace is rated for cone 10 (1305°C / 2381°F). The controller ia a PID w/ K type thermocouple. Controller cost $35.
Used kilns are available. A broken one can easily be repaired.
I also have a pi based controller that I built on another kiln for investment casting (burning out wax from molds) that allow different ramp temps for different times.
These are charts were provided by AI & google. They talk about pre & post heat... what is that??
It is also wise to pack the metal in a charcoal mixture or stainless foil to mitigate decarburization & scale.
If anyone else heat treats using a furnace please share your tips!
Bone vs willow charcoal?
Mix of ?
Thanks in advance!
