For shotai-shippo or plique-à-jour, the production process is similar to wired cloisonné. The difference is that for this technique, the copper base is dissolved with acid so that only the glazed surface remains.
In shippo (cloisonné), the base metal is referred to as tai, and sho means to omit, which is the origin of the name shotai-shippo. After the metal base disappears, only the silver outlines and glass-like sections remain. Pieces that use this technique are beautiful because of the way the silver glistens amid the transparent enamel surroundings.
1.Make compartments with silver wires on top of a copper base, and apply colored enamel glaze in the compartments.
2.After firing to fix these materials to the surface, apply vinyl chloride-based resin to protect the surface.
3.The piece is soaked in acid to dissolve the copper base. The protective film is removed and the piece is complete after being polished.
