Transparent aluminium is also referred to as aluminium oxynitride. It is a see-through ceramic of polycrystalline that is made from a structure of oxygen, nitrogen, and aluminium. This impressive material looks completely see-through and is incredibly strong. Transparent aluminium is four times as hard as fused silica glass, three times harder than steel, and a whopping 85% harder than sapphire.
Not only is transparent aluminium very tough, but it also has an extremely high melting point and can remain solid up to 1200 degrees Celsius. This means it can be used for products which need to withstand super high heats while also being see-through. Transparent aluminium is also resistant to damage caused by oxidation and radiation and offers good resistance to corrosion.
We actually live/reside in a enclosed eco system
We have a firmament above us
preventing the waters above coming into 'our space'
and the air we breathe and the gas in the sky, escaping
