What *is* cool about the process for ?transparent aluminum? is that it?s scalable. To
get
bigger pieces you just need a bigger press. Unfortunately it probably will never be as
cheap as large scale glass making which can be done on a continuous process.

Actually it actually *does* exist and is
reasonable to manufacture. Here?s the
article:

It?s basically a sintered process where the ceramic is formed (this particular one is
called spinel)
and the process is to put the powder in a press, raise the temperature and evacuate the
air.
The result is a clear crystal that has better properties than glass. The size of the
piece is only
limited by the size of the press.

THAT would be a big heated vacuum press
