I'm intending to PID my small apartment-sized oven range, but i also thought about ways to stabilize the temp in the oven. Sometimes I feel the IR radiation off the coils could be messing up some experiments, so I thought what if you placed a plate of steel on the coil at the bottom just above it like we do with the mold warming plates? If it were a 1/4" or thicker it might retain a little heat too and help stabilize while also blocking IR that way as well?
