This is a big 46″ parabolic mirror with a 1M focal length. The lens can reach about 2700F max collection. Not 100% sure about those figures yet as a mount is still needed and the mirror flexes a bit. Superheating steel wool creates surface nanoparticles when the wool turns bluish in color.
TRUE MIRROR, NOT MYLAR.
