Anodizing is basically an electrolytic process that is used to increase the thickness of oxide layer on a metal surface.
The anodizing process is very simple. First, submerge your pan in a chemical bath, for example sulfuric acid can be used. Then apply a low electrical charge on it.
As a result, an oxide acid is produced from the layer and forms the surface. When it is cooled the exterior part becomes anodized and much harder. Even harder than stainless steel.
Due to it’s stronger and more chip resistant ability, this material is used in different types of cookware. Also it is easy to clean and does not leach any aluminium into your food.
So experts urge using anodized aluminium cookware.
Cookware made from hard anodized aluminium has long life span as well compared to the regular aluminium. That is why anodized aluminium cookware is becoming popular day by day.
Hard anodized aluminium cookware is not completely non-stick. In order to clean it, you can use dish soap. Better if you do not use harsh cleaning products.
To prevent scratches it is important to store your cookware perfectly. Using a pot rack or, in-cabinet-slide-out racks are best ways to store your cookware properly.
Do not put anodized vessels on top or, inside of other pots and pans. As it’s extremely hard outer shell can cause damage to them. It can be used on the stove top as well as in the oven.
