Electrolytic gold Fox head pin by Bijoux Fix
A stick pin of a fox’s head by Bijoux Fix. The reverse marked “FIX”.
FIX (Bijoux FIX) was founded in 1823 and is credited to have invented the laminated gold technique often known today as rolled gold. Lamination bonds a thick layer of gold onto a base metal whereas plating adds a thin layer of gold normally by a chemical or electrolytic process. FIX became a generic name used when speaking of the finest quality gold overlaid products. They produced well designed art-nouveau items that had a substantial gold layer on a base metal.
French, circa 1920
