The certification of FILIGRANA DE PORTUGAL allows the consumer to be unequivocally informed that they are in the presence of an artisanal production, with specific and distinctive characteristics that set it apart from other filigrees produced elsewhere in the world, associated with an important and ancient social and cultural legacy.
The technical characteristics that define artisanal production are detailed in the Specifications Notebook, a normative document that regulates this process. In addition to the techniques, most of which are ancestral and predominantly manual, the tools and utensils used are also indicated, some of which have undergone mechanical improvements over time, without ever compromising the artisanal nature of this art. In the same way, the Specifications Notebook allows for conditions of product innovation, combining the filigree technique with new forms of production and design, as long as the preservation of the product's identity and authenticity is ensured.
