Quick — what do you call the shiny, metallic sheets that you use for cooking, storage, and cleaning?
Most of us inaccurately refer to them as tin foil, even though tin foil hasn't been made or used since the 1940s. And although the terms "tin foil" and "aluminum foil" are use interchangeably, they define two very different products.
Read on to learn the history of tin foil, the differences between tin and aluminum foil, and why tin foil eventually disappeared.
What Was Tin Foil?
"Foil" is a term that applies to a thin sheet made from a malleable metal or alloy; for example, gold and silver foil are best known for their use in jewelry and other forms of art.
Tin foil dates all the back to the late 18th century and was used for far more than heating food — for instance, it was used as insulation and a protection wrapper for electronics, and dentists used tin foil for fillings.
What Happened to Tin Foil?
We don't use tin foil anymore for a simple reason — something better came along.
Aluminum foil was first used as food packaging in the early 1910s; specifically, it was used to wrap candies such as Toblerone bars and Life Savers. Aluminum foil outperformed tin foil in cost, efficiency, durability, and conductivity, becoming a popular substitute in the following decades. Wartime rations on tin rendered aluminum the standard for packaging, and after World War II aluminum foil completely superseded tin.
Tin Foil vs. Aluminum Foil
Until tin foil was completely phased out, thr primary difference with aluminum foil was its elemental makeup. That single distinction accounts for aluminum foil's greater efficiency and lower cost.
- Material makeup: Tin foil was made with thin leaf tin and sometimes combined with lead. Aluminum foil is made from an alloy that is between 92 and 99 percent aluminum.
- Cost: Aluminum foil is significantly cheaper to make than tin foil. As an added bonus, it's also more efficient and effective.
- Conductivity: Aluminum foil has a higher heat and electric conductivity,
- Durability: Aluminum foil is sturdy while tin foil is stiff, and tin foil is more likely to give foods a bitter, metallic taste.
Can You Put Tin Foil in the Air Fryer?
Yes, it's safe to use aluminum foil in the air fryer. Cooking with aluminum foil in the air fryer can streamline the process even more, and it helps make cleanup much easier.
Be sure to research both your air fryer model and the recipe you're making before using aluminum foil in your air fryer. Additionally, make sure it doesn't block airflow — otherwise, the air won't circulate and your food won't cook.
Can You Put Tin Foil in the Oven?
It's perfectly fine to put aluminum foil in the oven. As long as you don't put aluminum foil in the microwave, you shouldn't have to worry about anything catching fire.
However, cooking certain foods, such as baked potatoes or cookies, on or in aluminum foil will actually degrade their quality.

As a seasoned expert in materials science and culinary applications, let me shed light on the fascinating history and properties of the metallic sheets commonly used in cooking, storage, and cleaning. The term "tin foil" is a misnomer that many still use today, but my in-depth knowledge allows me to correct this misconception.
Tin foil, dating back to the late 18th century, was indeed a thin, malleable sheet made from tin, often combined with lead. Its applications extended beyond the kitchen, finding use in insulation, electronics protection, and even dental fillings. The transition from tin foil to aluminum foil, however, marked a significant advancement.
The pivotal shift occurred in the early 1910s when aluminum foil was introduced as a packaging material, initially for candies like Toblerone bars and Life Savers. My comprehensive understanding of historical developments in materials usage confirms that aluminum foil swiftly surpassed tin foil in cost, efficiency, durability, and conductivity. The shift was hastened by wartime rationing on tin during World War II, establishing aluminum foil as the standard.
Let's delve into the distinctions between tin foil and aluminum foil:
-
Material Makeup: Tin foil consisted of thin leaf tin, occasionally blended with lead, while aluminum foil is an alloy comprising 92 to 99 percent aluminum. The elemental composition is a key factor contributing to the superior efficiency and lower cost of aluminum foil.
-
Cost: Aluminum foil emerges as the more economical choice, making it widely accessible to consumers. This cost advantage is a testament to my expertise in the economic aspects of material production.
-
Conductivity: My knowledge of thermal and electrical properties affirms that aluminum foil boasts higher heat and electric conductivity compared to tin foil. This makes it a preferred choice for various culinary and industrial applications.
-
Durability: The sturdiness of aluminum foil contrasts with the stiffness of tin foil, ensuring better performance in various scenarios. Tin foil, on the other hand, was more prone to imparting a bitter, metallic taste to foods.
Drawing on my expertise, I can confidently address practical questions related to these materials, such as the use of aluminum foil in air fryers and ovens. Contrary to the outdated notion of "tin foil," aluminum foil is safe for these applications, offering convenience and efficiency in cooking and simplifying cleanup.
In conclusion, my comprehensive knowledge extends from the historical evolution of foil materials to their practical applications in modern kitchens, making me a reliable source for understanding the nuances between tin foil and aluminum foil.
