The price of the foil has been reduced to a great extent. Aluminium foil gained significant importance when the first rolling plant for aluminium foil opened at Switzerland. The manufacturing plant was opened by Dr. Lauber, Cie, Emmishoen and Neher. Aluminium is no longer considered a precious metal, but the evolution of the aluminium metal reveals the importance of the product and its service to the modern world, which cannot be ignored.
He's always happy to share his passion for history. Use the contact form if you want to get in touch with him. One of the most innovative uses of aluminum foil came in the early s. The aluminum Christmas tree debuted—complete with foil-covered branches and decorations. Aluminum foil has a shiny side and a matte side. The shiny side is produced when the aluminum is rolled during the final pass.
It is difficult to produce rollers with a gap fine enough to roll a single sheet of foil. For the final pass, two sheets are rolled at the same time, doubling the thickness of the roll. When the sheets are later separated, the two inside surfaces are matte, and the two outside surfaces are shiny. Aluminum foil is also used to make aseptic packaging. This type of packaging enables storage of perishable goods without refrigeration.

Members Area. Buyer's Guide. Quick Read The origin of aluminum foil can be traced by to the early s. Take-Away Facts An early commercial use of aluminum foil One of the first commercial uses of aluminum foil came in Foil leg bands were used to identify racing pigeons. Billions of containers are produced each year Approximately 7 billion aluminum foil containers are produced annually.
This production rate nets to containers produced every second. The first actual aluminum extraction occurred in Danish physicist Hans Christian Oersted used to isolate aluminum for the first time. Well, so the story goes — his process probably led to a too impure extraction.
Many scientific minds would dedicate themselves to creating superior versions of the aluminum extraction process from this point onwards. Friedrich Wohler, a German chemist, managed to take the process to its next stage of evolution. By he was extracting pure aluminum powder, then by , he successfully created small balls of aluminum in a solidified melted form.
This would significantly advance the field, and other scientists would launch their work off his process for years to come. His was also commercially successful for the first time — from the process's perfection in until , his aluminum production scaled up to around 45 tonnes a year.
When aluminum first hit the markets in , it made quite an impression on the general public. It resembled silver in its appearance, was expensive and lightweight, and could be molded to make jewelry and art.
Shortly after, in , the first book we believe about the metal, titled "aluminum," was compiled by the Tissier brothers. Their process led to The demand for the metal was booming during this period. The factory responded to the need — it scaled from The factory was initially called the Pittsburgh Reduction Company, but it would eventually be renamed the Aluminum Company of America in Alcoa is still in business and trades on the New York Stock Exchange.
Surprisingly though, one of the most significant breakthroughs in the manufacturing of aluminum was still yet to come. In , Carl Joseph Bayer, a chemist from Austria, managed to extract alumina from an alkaline solution known as aluminum oxide. This process is known as the Bayer process , and it remains the technique used in the production of nearly 90 percent of all aluminum around the world. The effect of these developments and the general scaling of production could be seen in the falling price of aluminum over the ensuing years.
So in around years, aluminum went from mystery metal to replacing tin as the dominant kitchen foil! The 19th century was a period of transition from tin foil to aluminum foil for processes worldwide.
Robert Victor Neher created a continuous rolling process in and managed to patent it in the same year. He then opened an aluminum rolling plant in Kreuzlingen, Switzerland. Establishing the plant in Europe's heart offered various companies a chance to shift their current packaging methods.
In , the Tobler Company used aluminum foil to wrap its famous triangular chocolate bar, Toblerone. Another surprising use of aluminum was discovered by Richard S. Reynolds, the creator of Reynolds Wrap. He set up the U. Foil Company in to supply wrappers to candy and tobacco companies. Until that point, like most others, the company relied on tin for their unique wraps.
When the price of aluminum decreased in the s, the company quickly shifted to using this lightweight and non-corrosive material.
The fact that it could be rolled into thinner sheets than other existing alternatives was a big boon for Reynolds. Once the shift to aluminum began, there was no slowing it down. By , Reynolds began using aluminum foil to pack materials for the first time. In , another interesting development occurred within Reynolds' brand when an employee supposedly used an extra roll of aluminum foil to save his thanksgiving dinner after being unable to find a pan for the turkey.
When the trick worked, the company expanded its aluminum push even further. The rest, as they say, is history — aluminum foil is dominant in cooking, and you can still buy aluminum bakeware at the supermarket today.
For all the advancements and fine properties, the Second World War was the primary reason factories' production shifted from tin to aluminum. During this period, Japan had control over 70 percent of the world's tin supply, which directly conflicted with America's needs.
Once this boom began at the local level, there was no turning back. Aluminum advancements continued to develop well into the second half of the 20th century, with new applications popping up everywhere. You'll certainly recognize a few — sealed TV dinners, cartons, and blister packs. The rise of tin foil hats in connection to conspiracy theories added to the demise of the material.
As tin is an okay electrical conductor and weakly magnetic, some believe it can stop "mind-reading" waves from escaping or "mind-controlling" waves from getting to your brain. A MIT study tested tin's successor aluminum's ability to block radio waves and found that for some frequencies aluminum amplified the waves!
Frequencies between 1. It makes you think! Also, I haven't seen a study on tin-based hats yet
