Oxidation is a chemical process that produces the transformation of a body as a consequence of the action of oxygen or an oxidant, which is that element or material that oxidizes, such is the case of oxygen which is considered an oxidant par excellence.
Whenever an element comes into contact with oxygen, with air, basically, its oxidation is generated, however, mostly that occurs with the metallic elements that are exposed to direct contact with both oxygen and water as well.
So the oxidation process generates rust. Rust It is precisely a compound that is obtained by combining an element that is metal with oxygen. Meanwhile, the oxide is easy to recognize at sight because on the object in which this transformation was carried out, a layer of brown and reddish color can be seen. Any metal that is exposed to air or humidity undergoes this process and the aforementioned coloration in its appearance is certainly characteristic.
A clear example is obtained from observing the typical iron garden chairs that surely someone has seen in the grandmother's house or in some other old house ... the passage of time and that exposure to air and different climatic conditions through the years will generate the rust of those chairs.
It should be noted that in recent years, that natural oxidation that iron undergoes has become a hyper-demanded trend at the behest of decoration. Most people who like to acquire antiques especially look for iron pieces to be presented with that oxide because it gives them a unique aesthetic that is linked to the history of the piece and also guarantees its authenticity in terms of antiquity.
