Palais Royal held by a "Meilleur Ouvrier de France" (best French craftsman). The slightly ivory tone of the Brianchon - decorated rim, is obtained by a clever mixture of lustres. The encased motifs are entirely touched up with paste before being painted and dusted. The different colors are fired separately, from the most resistant to the most fragile - each scene is different and each piece requires to be given its unique aspect.

The traditional Limoges glazing technique used requires, for porcelain, as many firings, saggar-firings, as there are colors.

It is part of the entirely hand-painteddecorating tradition called "pearls and glazes" which Martial Raynaud manufactured before WW1, assisted by the famous enameller Alexandre Marty.
