Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. 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 so chemically reactive that native specimens are rare and limited to extreme reducing environments. 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.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."
Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[69] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."
The -ium suffix conformed to the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium (all of which Davy isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802. The -um suffix is consistent with the universal spelling alumina for the oxide (as opposed to aluminia), as lanthana is the oxide of lanthanum, and magnesia, ceria, and thoria are the oxides of magnesium, cerium, and thorium respectively.
The aluminum spelling is used in the Webster's Dictionary of 1828. In his advertising handbill for his new electrolytic method of producing the metal in 1892, Charles Martin Hall used the -um spelling, despite his constant use of the -ium spelling in all the patents[58] he filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easier-to-pronounce word with one fewer syllable, or that the spelling on the flyer was a mistake.[citation needed] Hall's domination of production of the metal ensured that aluminum became the standard English spelling in North America.
- Q:It looked so good and I can't remember how I linked on to itI want to make it for my quot;mounds lovingquot; 32 yrold sonI sure hope somebody remembers! Merry Christmas!!!
- a good diet has lean protein like chicken, turkey, cheese nuts fiber are in things like bread and pasta great snacks are a few slices of turkey or chicken and a slice of cheese apple and cheddar cheese(apple has good soluble fiber) fiber one cereal and dessert bars are great sources of fiberI love the honey cluster kind and original with some honey.
- Q:I'm buying a sheet of sterling silver, and I'm not sure what gauge i should getI was thinking of getting gauge 30, which is .25 mm, but I'm not sure if it will be durable enoughI'm going to be cutting the silver sheet into fairly small pieces, putting them through a test, and then I'm going to look at how much they tarnishedIs 30 gauge silver as flimsy as household aluminum foil, or will it hold it's shape if bent in half?
- 30 gauge is a heavy thick sheet of silverIt will hold it's shape.
- Q:Do I put them in hot or cold water??? I am going to cook them in a turkey deep fryer tonight and have to make a lot of themI know that I will have to dry them off before cooking but I also heard that if you cut up appl;e ahead of time you add a little sprite to a spritzer and spritz them to keep them from turning brown Thanks for your help.
- Put them in cold water and refrigerateIf you add some sugar to the water, that will help them brown when you fry themJust make sure you don't store them in aluminum, or cover them with aluminum foil-it will turn the potatoes a purply black-not harmful but very unappetizing.
- Q:I have blonde hair so this should work but I need to know how many packs of kool~aid I should use and how much water I should mix it withI have tried this three times but it always comes out as soon as I rinse itI'm only doing one streak of hair and I'm doing it purple by mixing blue and redHow much water and how many packs of kool~aid should I use for the best results?
- okay, first you put one pack of kool-aid into a bowl and add one drop of conditioner and one drop of water and mix it upthen apply to your hairthen take aluminum foil and cover the piece leave it in for at least six hours and take it out and rinse it, it should stay in for about a week or so:)
- Q:I know or at least I have heard you not to use water on cast iron skilletsI have also heard not to wash at all to preserve the flavorBut this sounds A bit absurd to meSo if not water what do you use.
- Was his diet layed out for him by a nutritionist/dietician? If so, he needs to go back and let them know that he feels hungry all the timeThey can suggest alternatives that will increase satiety (feeling satisfied) that will not jeapordize his blood sugar controlThis is very important, because he will not be able to adhere to his diet very long if he's always hungry.
- Q:what's a better more eco-friendly alternative instead of plastic sandwich bags?
- no its not,.its not even eco friendly,.
- Q:Difficult math question- how to solve?
- Rice, peas pinto beans, corn and green beans will make a good meal.

- Q:2007 frontier nismo 2x4 crew cab v6
- You could take them to court and try to convince the judge they are not doing everything they can to accommodate handicapped peopleHowever they would just have to show they are doing the best they can to keep the elevator operational.
- Q:My husband and are taking our 4 kids camping in the pop-up in 3 weeksWe will have a microwave and propane stove top and of course a campfireI have breakfast covered, but would like ideas for make ahead lunch and dinners that can be served or re-heated with little effort I will be preparing and cooking them at home a day or 2 before we leaveMy kids are 2,4,5, and a 7 month old who won't need the foodAny ideas, recipes, or web site links would be great thanks.
- I would screw them back in and leave emOtherwise you will have holes in shingles and woodTar would probably seal it but that's just something that could screw upBut still tar it good under the head of bolt and over top.
