In an exhibition of haute jewelry, designed by a Frenchman but made in New York, a description of some of his bracelets uses the French word “paillonne” to describe the enameling.
A search on that word indicates it is layering foil in enamel.
Haute watch makers use this word to describe foil decorated enameled watch faces; and in the descriptions of their white enameled watch faces they use the words “grand feu” enamel, which I think means high fired vitreous enamel.
These French words certainly are brief compared to my bulky string of English words, but they are not in the index of my enameling books.
Does anyone know if there are more substantial definitions, or if these are simply French words used for haute jewelry marketing purposes?
