Actually, that is alumina, not aluminum.
Alumina is the basic ore. I'm speaking of far more exotic material
that was manufactured and designed by Sandia Labs. Throw a switch and it
the large sheet is now clear as glass - throw it in reverse and it is opaque.
Not Alumina:
Any of several forms of aluminum oxide, Al2O3, occurring naturally as corundum,
in a hydrated form in bauxite, and with various impurities as ruby, sapphire,
and emery, used in aluminum production and in abrasives, refractories,
ceramics, and electrical insulation. Also called aluminum oxide.
