Know-how

Molding and smelting

This stage requires a great amount of experience and know-how to assure the quality of this operation which begins with the production of a model called the « chief model ».

With the lost wax process, plaster is casted around this model. It is then unmold by cuting the plaster in two and reconstituted replacing the model by wax. The mold is heated and the wax flows out by an opening designed for this purpose.

The metal is then casted into the mold. After cooling. The mold is broken to free the bronze piece.

Very precise and of high quality, the lost wax process provides high definition in the smallest details.

Deburring and chiseling

To conclude the smelting work, the bronze piece is deburred to remove all imperfections.

The chiseling involves numerous houres of work and the skills of a highly trained profesional. It will give to the final work its polish and relief to the smallest details. Chiseler is an art craft which requires a minimum of three years of apprenticeship.

Gilt, silver-plating and patina

When all the different components of an object are ready, they go through an electrolysis process in baths containing water along with metal salts solutions as well as other chemical products. A low voltage current induces the dissociation of the molecules of metal salts and as result the laying of a gold or silver coating on the immerged pieces.

The work is not over yet and remains the finish with different recepies to give color to the gold or silver. The finish can also include the artificial aging of the piece.

Mounting and electrification

The different components of the object are then carefully assembled and eventualy electrified to the standards of the destination country.
