The tube hammering technique consists of several stages to transform the tube into a piece with the desired pattern. First, flatten both ends of the tube and use two clamps at each corner to hold it together.

Once you secure the tube, you heat it to make it smooth. This is done using heating tools, such as a blowtorch. The heat helps make the metal in the tube more malleable and easier to work with.

Once the tube is hot and in a suitable state for forming, the hammering process begins. To achieve this, we use a small punch with a medium-sized tip. They gently hit the tube with the punch, following the chosen or previously designed pattern.

During the hammering process, it is important to consider the rigidity of the metal. The torch can overheat the metal if it becomes too stiff to work with. Reheating involves applying heat to the metal to soften it and make it more malleable once more.

As the pattern grows, you can add a texture to the metal. Instead of using a medium-sized awl, one uses a fine point awl to create this. With this tool, you hit the metal in a specific way to make it look how you want it to.

The process of hammering and reheating is repeated until the final result is reached. With patience and skill, they can transform the tube into a unique copper eco-friendly bracelet with a personalized design.
