One should also keep n mind that the ink is a mess, and should be removed and disposed of in an appropriate non-polluting way; that the Al is _thin_ and will pit and corrode very easily (from salt air, as well as food drippings); it will also very easily lose what little polish it may have when you wipe the surface clean. I wouldn't say the sheets are tempered, but they do not readily bend more than once on a given line - and watch out for the resulting very sharp edges!
Every once in a while, the Georgia Tech parabolic design comes due for a mention. They made plans available for a spirally developed 'Fresnel mirror' that seems to be practical if you have an ample source of flat reflector material such as the printing plates. (I suppose it's on a web site, now?)
