A pure copper electrotype plaque is a sophisticated art object produced by using electrolysis as the following steps.
Based on a drawing, our engraver molds an original model in clay. Plaster is then used to produce a negative mold.
After graphitized on the surface, the plaster model is soaked in a copper sulfate solution tank as negative electrode, while a copper plate is used as positive electrode. The tank is electrified for 120 to 220 hours to form 1 to 1.5 mm thick copper electrodeposit on the whole graphitized surface.
The electrodeposited copper, peeled off from the plaster model, is polished and then finished with chemical dye or gold- or silver-plating.
Golden Pavilion (Kinkaku) is a gilded three-story reliquary hall erected by shogun Ashikaga Yoshimitsu (1358-1408) in Kyoto. The wooden structure was destroyed by arson in 1950, but an exact reproduction of the original was completed in 1955
