not long. photoshopped up the designs. cut steel plates. enameled black at high temp. cloisonné (yes i did cut and paste for the é) effect done by bending copper wire to form the shapes, then filling in with colored enamel. baked again to set the wire and enamel, epoxied into the wood? not sure about the last step. he also does enamel silk screening by separating colors in photoshop, printing each color to a transparency and using it to mask a photo emulsion screen, sifting enamel through the aligned screens one color at a time. pretty cool. pm me if anyone wants custom enameling! he's retired and up for it. based in new england
