When they can do transparent aluminum, I'm in!
edit: yes I know there's a ceramic material called ALON, which the manufacturer calls transparent aluminum because it contains aluminum oxynitride, but I don't think that's what Scotty meant. ALON is about 30-35% aluminum, same as the amount of lead in leaded crystal glass, which isn't "transparent lead".
Aluminium Oxide (Al~2~O~3~) can be crystal clear too, it's just Sapphire, I have a chunk of it on my wrist right now, looks pretty clear to me, and almost as hard as a diamond.
