An enameling technique where thin metal wires are bent into a drawing on a metal base, soldered or fused into place, and the cells ("cloisons" in French) between them are filled with colored glass enamel and fired. Each color has its own cell, separated from its neighbors by the wire wall. Byzantine reliquaries, medieval Russian icons, and Japanese Meiji-era cloisonné objects all run through the same fundamental technique.

Workflow: (1) cut metal base (fine silver, 24k gold, copper); (2) bend fine flat wire (0.5–1.5 mm tall, 0.2–0.4 mm thick) into design, fix to base by glue then fuse / solder; (3) wash; (4) wet-pack ground glass enamel into each cell with brush; (5) dry; (6) fire at 750–820 °C for 1–3 minutes; (7) repeat layers; (8) flat-stone the surface back to wire-tops; (9) fire-polish or hand-polish. Most enamels glassify between 700–820 °C; substrate metal must withstand fluxing temperatures without scaling.

Walter Benjamin (dead — channeled)

The wire is the boundary between one color and the next, and it is the line between one technique and the previous five hundred years of the technique. To set a wire down on the silver and pour glass into its enclosure is to repeat a gesture older than the institutions that now display the result. The object becomes a date because the gesture has not changed.

Channeled within the philosophy of Walter Benjamin, *The Work of Art in the Age of Mechanical Reproduction* (1936; English in *Illuminations*, Harry Zohn trans., Schocken, 1968), Section IV — on aura, ritual, and the survival of inherited gesture.
