Aluminium ( /ˌæljuːˈmɪniəm/ AL-ew-MIN-ee-əm) or aluminum (American English;
/ˌəlˈuːmɪnəm/ ə-LOO-mi-nəm) is a silvery white member of the boron group of chemical elements. It has the symbol Al, and its atomic number is 13. It is not soluble in water under normal circumstances.
Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is too reactive chemically to occur natively. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite.
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

music: hagel / lyrics: lodmalm
reptile sleep
the fix runs deep
alone with mirrors
a blank reflection stains the glass
liquid eyes
late goodbyes
calling from a distant waste that you can't find
and now when all is said and done
nowhere left to run
bittersweet aluminium - left in my mouth
diamond dreams
tainted past
it comes together - all together - it won't last
exiled waves
heartbeat lost
set the world on fire now at any cost
