There is a difference between strength and tenacity. Glass is very hard, but brittle. Aluminum is soft, but strong.
While I do not doubt that aluminum is strong. It's a question of how strong is the transparent aluminum. Is it strong enough to contain a million liters of water without failure?
I'm just asking, because I personally do not know how strong it actually is.
Do you know the answer to my question I posed? 🙂
