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.
Ah yes, but can you make in sheets 60 feet by 10 feet by 1 inch
thick and
withstand the pressure of 18,000 cu ft of water? :)
THAT would be a big heated vacuum press
But where will you get the whale?
