Point taken - I believe you are referring to the solar furnaces beloved of American Science Fair students. Someone (apologies but having started to write this I can't navigate away from the page to find who it was - see below) mentioned having a go at lighting a fire with one of these mirrors and I took it they wouldn't be carrying a bag full of them and a parabolic frame to hang 'em on..?
"...but these come pre-polished to a high enough standard that you can see your face in them from 30 feet away (the black line reflected in this one is a curtain track on the ceiling 6ft above the desktop), have a nifty hole in the middle either for sighting through (signalling) or mounting on a stick (shaving if you're male / make up and general gazing at yourself if female).
Should we ever get any sun, I'm going to have a stab at firelighting with them too."

Nice mirror mate, Belzebob made me one quite similar except it has an edge on it too as a spare blade. (Also so I can look sharp )
