A single opener takes from 10 to 12 weeks to make at the foundry. The artist and his craftsmen (Michel Audiard’s art foundry obtained the “Living Heritage Company” label in 2007) attach great importance to capturing all the details of the hand in metal for eternity. The object is made from tin or bronze and then silver-plated, black nickel-plated or gilded with 24-carat fine gold.… But in reality, we can imagine all kinds of creations since these artworks are unique pieces and our craftsmen have mastered all the finest goldsmith skills (casting, chiselling, polishing, setting, etc.). We received a request from a vineyard owner, for instance, who wanted to have us set a small flint stone from his property in his opener.
