History of Aluminium

What is Aluminium?

To most people, aluminium is a light, silvery metal used to make a variety of products from airplanes and automobiles to pots and pans and baseball bats. Nearly everyone uses aluminium foil. However, it is much more than that. It is a chemical element-one of 90 naturally occurring elements on earth that serve as a building block in nature. As an element, aluminium has unique physical and chemical properties. It is the 3rd most abundant element in nature, representing about eight percent of the earth crust, or surface. Only oxygen and silicon are found in greater quantities. Aluminium is everywhere, it is
present in soils and clays, minerals and rocks and even in water- but not as a metal.  This is because aluminium is a very chemically active element. Because of its chemical
activity and particularly its affinity for oxygen, aluminium is not found in its free or metallic state in nature. Indeed, metallic aluminium was unknown until about 150 years ago. Instead, aluminium is always found chemically combined with other elements, particularly oxygen.

Aluminium Cookware Facts :

Aluminium cookware is light, durable, and great for cooking and conducts heat more efficiently than stainless steel. With proper care, it can last a lifetime.
More than half the cookware sold each year is made of aluminium. Ever since aluminium has been readily available, consumers, professional chefs and commercial food processors have welcomed it’s advantage for food preparation. Aluminium is light and strong, so even a large sturdy pan is easy to handle. It imparts no taste or odour to food, is durable and, best of all, and has excellent cooking characteristics.
It loses only about seven percent of the heat it receives, leaving 93 percent of the heat to cook your food. This means that aluminium cookware transfers heat very efficiently and evenly to the food inside, rather than to the air outside it.  Electrolytic reduction, invented in 1886, brought aluminium within reach of the average consumer and its first large volume use the tea kettle began in 1889. History tells us that the first aluminium frying pan in the United States was stamped from the sheet metal in 1890.
Most of the aluminium produced before 1900 was used to make cooking utensils. By 1914, automobiles became the largest aluminium market, but cookware still claim a sizeable percentage of all aluminium produced. Aluminium is used not only in family kitchens,
but also for vats, tanks and vessels used in making wine, brewing, preserving fruits and other food processing.The first use of Aluminium in the world as well as in India was to make utensils for cooking. Aluminium and food have gone together since and even before the modern aluminium industry began. Napolean III reportedly served his most honored guests at state banquets with plates made of aluminium, then a rare and precious metal. Less important guests had to eat from plates of pure gold.Gram for gram, aluminium
 conducts heat almost twice as well as copper and about nine times than stainless steel.With proper care, it can last a life time. New utensils should be washed before use to remove manufacturing oils. Exposed aluminium surfaces will not rust, but they can be scratched by sharp tools. They should be cleaned with non-abrasive pads and cleaners. Extreme, rapid temperature changes can damage cookware. Utensils should be allowed to cool before
washing. Acid or salty residues should be washed off soon after cooking and immediate drying helps preserve appearance.  Aluminium cookware is shaped from sheet metal or cast from molten metal. Then finishes are applied and handles are attached. Aluminium utensils come in various thickness or
gauges identified by number. The smaller the number, the thicker the aluminium, For example, 8 gauge aluminium is 0.125 inch thick, almost four times thicker than 20 gauge aluminium.
