Another option for you, find someone that has a kiln. I have an old
electric kiln that I got for free because it was old. I added a simple
thermocouple temperature gauge to it and it works great for annealing and
heat treating small parts. My next project is actually adding solid-state
relays and a PID controller so I can do some more precise temperature
control. If you do this, or use a modified oven, do be careful. There is
a reason that oven doors lock at high temperatures.
