Oxidation of aluminum, formation of a thin layer of aluminum oxide.
Aluminium is a very reactive metal, but it's reactivity is masked by the thin film of aluminium oxide that covers the surface. Anything that is acid will dissolve this film and leave the surface bright and shiny. Green vegetables contain a variety of acids that can do this.
because you can't see they don't shine
Plant shine also called leaf shine is made out of milk. It is rubbed on the leaves or poured in the soil, and mayonnaise can also be used.
which material does not loses its shine. Is gold
Oxidation of aluminum, formation of a thin layer of aluminum oxide.
Aluminium reacts easily with air, forming a skin of aluminium oxide which prevents further reaction.
due to refraction of light..
Aluminium utensils have thin oxide layer around them which can be dissolved by acids. Green leafy vegetables contain a variety of acids which can easily do it.
the mineral of the half gold rock is the aluminium it makes the rock have its shine in the inside and then it spreads out in the outside yep that is all...:-D
It will end up a little lighter than your natural color but will loose shine and can fall out.
The question isn't clear since the word "lustre" means "shine". If the question is, "Does the element aluminum lustre?", then the answer is yes, because metals in general are shiny.
Most metals lose their shine as they react with gases in the atmosphere or in a liquid.. The surface layer may react to fom an oxide, hydrated oxides, sulfide, sulfates, carbonates. Generally ths process makes the surface dull and it may get pitted. The process is called corrosion when it is iron rusting and tarnishing when it is silver forming black silver sulfide or copper forming a mixture of greenish products, "patina" whose composition depends on the location.Some metals do not lose their shine. Common examples are gold and platinum which are used as jewellery. Aluminium still looks shiny but there is thin layer of aluminium oxide which prevents the reactive aluminium metal from corroding.

The light waves will bounce off of the thin layer of metal and shine on another object.
Sulfur gas (and other gases) can cause silver to oxidize (loose electrons). The silver looses it's shine and becomes tarnished.
Loose or corroded ground connection on the right headlight assembly.
