When the leaves have cooled, they must be heated again.
Artisans alternate between heat and hammering until desired the size and shape are obtained.
The process causes oxidation and the objects become black.
Patterns are created on objects by the technique of regrowth in which drawings appear in relief after hammering on the inner side of the objects.
Details are then refined on the outside to complete the work.
Completed objects are then soaked in boiling sulfur water to remove traces of black residue, rubbed, immersed in a juice of tam and then rinsed.
Following the washing process, the finished products will be bright and shiny.
