What's the difference between aluminium and mellite?
Aluminium
Definition:
(n.) The metallic base of alumina. This metal is white, but with a bluish tinge, and is remarkable for its resistance to oxidation, and for its lightness, having a specific gravity of about 2.6. Atomic weight 27.08. Symbol Al.

Mellite
Definition:
(n.) A mineral of a honey color, found in brown coal, and partly the result of vegetable decomposition; honeystone. It is a mellitate of alumina.
