The 1.5 mm thick brass slab comes from Auvergne. It is mass worked, to coerce the matter and see how it reacts. Thus, it is heated and arched to get a 24 cm high rectangle without any weld. The two 4 cm high legs are the only parts welded with silver, a jewellery technique. Finally, we perform a circular brushing with 3 different brushes to give the brass a special texture, in our workshop in Béarn.
