A primary function of the leafâs waxy cuticle is to reduce water loss through the leaves, which is particularly important in arid deserts with little rainfall or Mediterranean climates with seasonal rainfall.
The first plant designed for rolling aluminum foil was opened in 1910. Aluminum foil replaced tin foil, when the Dr. Lauber, Neher & Cie., Emmishofen aluminum foil rolling plant in Kreuzlingen, Switzerland, was opened by J.G. Neher & Sons.
Aluminium was first isolated by Hans Christian Oersted in 1825 who reacted aluminium chloride (AlCl 3) with potassium amalgam (an alloy of potassium and mercury). Heating the resulting aluminium amalgam under reduced pressure caused the mercury to boil away leaving an impure sample of aluminium metal.
