Kintsugi (Golden Repair)

Kintsugi (金継ぎ, “golden joinery,” also called kintsukuroi) repairs broken pottery or porcelain by gluing the pieces back together with urushi, filling any gaps with a paste of lacquer mixed with flour or other fillers, and once that base repair cures, dusting the final coat along the seam with powdered gold, silver, or platinum. The repair line stays visible on purpose. Rather than hiding a break, kintsugi turns it into a deliberate part of the piece, a philosophy closely related to wabi-sabi’s appreciation of imperfection.

Because it uses real urushi, a genuine kintsugi repair cures over weeks, not the minutes an epoxy glue would take, and once fully cured it’s chemically inert and safe for food contact, the same as any other urushi finish. Many modern DIY “kintsugi kits” substitute epoxy resin and metallic powder for speed and convenience; some of those are food-safe once cured and many aren’t, so a repair made with one shouldn’t be assumed safe for eating or drinking unless the specific product says so.
