A patina layer is a thin layer that forms on the surface of certain materials after a while. Consider metal, wood or stone. This is a natural process where the material reacts to air, moisture or other environmental factors. This processing gives the materials a 'used' appearance. This is a sought-after feature in industries such as art and design.
How does a patina layer form?
Through a combination of chemical reactions and oxidation on the surface of the material, a patina layer is created. This patina layer varies in colour and texture from one material to another. Copper, for example, gets a green patina layer. Iron and steel, on the other hand, take on a rusty patina. The formation of this layer is a gradual process. The speed of this is affected by several factors, such as weather conditions.
Besides its unique look, a patina layer can also serve as protection. For example, it prevents discolouration or surface degradation. This will extend the life of the material.
Maintaining a patina layer
Depending on the type of material, the maintenance of a patina layer varies. You can also choose to retain the patina layer to get that lived-in look. When it comes to maintenance, it is important to choose the right cleaning agents suitable for the material.
