Decor covering branches and open flowers and iridescent buds of red, yellow, bluish, orange-colored oxidation on an amber background. Signed "Duc A. de Caranza" on the base. In 1902, he filed a patent in 1902 with Madame Duc for the "decoration of electric lamps and, more generally, of all glass, crystal and other transparent materials" which made it possible to obtain a luster metallic. A patent for the same process is granted to them in Germany in 1904. Their association and the signature they use at this period, Duc. A de Caranza, could sometimes think of a noble title.
