Here's an off-the-wall method that I intend to use. I installed a digital controller on the small electric kiln I use for case coloring. It should hold the pot at the correct temp with no problem, and it's top loaded. It'll also be easy to shoot the temp with my infrared thermometer.

Regards
Ken

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
