STEP 1 Molding
Today this process has been developed by molding the copper surface to form the ’cloisons’.

STEP 2 Outline Cutting
Cutting molds are made separately, then cut to the exact outline of the design. Outline cutting molds may be required depending on the complexity of the design. If a center hole or cut-out is required, an additional cut-through mold must be used.

STEP 3 Coloring
Enamel is composed of glass-like material combined with metal oxides and clay into fine powder. Cloisonné powder cannot be mixed like paints or soft enamel, as each color returns to its own shade after heating.

STEP 4 Firing
Colors are fired one at a time at 1,600F for two to four minutes to stabilize the enamel and prevent color bleeding.

STEP 5 Stoning & Polishing
Each piece is fully cooled. Finishing is by rubbing the surface with a carborundum stone until all excess color has been worn away. Surface then polished until smooth and shining.

STEP 6 Attachment
Attachment is soldered onto the back of each piece.

STEP 7 Plating
Plating now can be processed. The quality of plating varies with the length of time the metal is soaked in the plating liquid. Click on the link to see the different plating colors available for this process.
