Blackening

Blackening

Metal blackening is an old technology used to protect metals against corrosion and weathering. If done correctly, this process can perfectly protect the metal and its appearance.

Blackening of metals is usually done using chemical preparations that contain different types of acids. These acids are used to remove loose particles from the surface of the metal and thus give the metal a shine.

The next step is to clean the surface and remove the old coating. This is done using various techniques such as rubbing, polishing or using sandpaper. Then the surface is soaked in a special solution that contains acid and iron oxide. This process is called oxidation.

When oxidation is complete, the surface is washed and wiped with clean water. The surface is then treated with another product containing various lead compounds to prevent further corrosion damage.

Finally, the metal is polished again and is ready for use. Metal blackening is therefore a useful process that protects the metal from damage and gives it a durable shine.
