Maison Ercuis Silver metal champagne bucket Maison ERCUIS - To be picked up at St Ouen Ercuis is a French goldsmith's house founded in 1867. The know-how of the House is maintained by highly qualified goldsmiths, who perpetuate a traditional manufacturing process. Each goldsmith's piece is made up of a certain number of elements prepared separately. A worker is involved at each stage. The final piece is assembled by silver soldering, tin soldering and then possibly crimped. It is then chiselled with great care. Once assembled, each piece is polished and then silvered by electrolysis. Once controlled, the finish of the metal is thus perfect.
