Interesting! I wonder if they reformed them into parabolic form? I didn't check the math yet, but with a long focal length - say 12" - not much curve is needed.
In the mean time, my oven - with a focal length of 10" - is ready to test. Unfortunately it's raining here today & corrugated paperboard & white glue do notta lika the raina!
