Cast iron of the bust.
"To attend the birth of a work of foundry cause an intense emotion, made apparently revealing of a mystery whereas it acts, and that only imports, of this form of genius which conceals, in the event, the hand of the craftsman. (Jean de Bengy. "the adventure of fire and metal")
The collaboration of the sculptor with the founder is essential. The founder must as well as possible respect the work of the artist who will intervene with each stage, of the control of wax to polishing and the patina.
The sculptor created his model out of plaster and the founder perpetuate the work in metal.
Confidence, collaboration necessary between the various protagonists led Daniel Goupil to choose the Foundry of Coubertin, one of the workshops of control of the Foundation of Coubertin.
The foundation was born from the meeting of Jean Bernard (renovating of the Companions of France) and of Yvonne de Coubertin (heiress of the property).
One of their objectives is to allow a conservation of the techniques and savoir-faire while continuing a research on technical innovation.
At the Foundry of Coubertin, the sculptor finds experts with his listening, able to develop with him a reflexion on the realization of his work and the quality of the finished.
The Foundry of Coubertin(...) corresponds perfectly to the vocation of the Foundation of Coubertin, place of meeting of the hand and the spirit, the sculptor while being a perfect symbiosis.
