Kintsugi (金缮／金繕) is a traditional Japanese technique of repairing broken pottery by filling cracks and breaks with lacquer and decorating them with powdered metal (gold, silver, etc.). Instead of hiding damage, it highlights the “scars” as part of the piece’s history and beauty. 

Yes — if repaired using traditional urushi lacquer and real metal powder (gold or silver), the piece can be food‑ and drink‑safe.  

However: avoid exposing it to extreme heat (microwave, oven), and avoid dishwasher or strong cleaners — these can damage lacquer or metal surfaces. 

Follow these rules for best longevity:

• Hand‑wash only with soft sponge or cloth and mild detergent / warm water.  
• Rinse thoroughly, dry immediately with soft cloth — avoid soaking or leaving water too long.  
• Never use dishwasher, microwave, oven, or expose to abrupt temperature changes.  
• Avoid abrasive sponges, hard brushes, bleach, acidic or alkaline cleaners, and sharp cutlery against repaired lines — to prevent scratching or damaging the lacquer/metal finish.  

Not all broken ceramics are suitable for Kintsugi. The technique works best when the fragments fit together neatly and the base material and glaze are compatible with lacquer adhesion. Extremely thin pieces, severely shattered ceramics, or surfaces with glaze that resists bonding may not be reliably repaired using traditional Kintsugi. Experienced practitioners recommend carefully assessing each piece before attempting restoration.

In addition, some modern “quick fixes” using epoxy resin or other artificial materials, while convenient, generally do not adhere to traditional standards and are not recommended for vessels intended for food or drink.

Traditional Kintsugi using urushi lacquer can last a very long time if properly cured and maintained — many preserved works have endured for decades, even centuries. If the lacquer layer degrades due to wear, chemical exposure, or extreme environmental conditions, experienced artisans can re‑lacquer or restore the piece. This ability to be repaired and renewed is one reason why Kintsugi is considered a sustainable and regenerative art form.

Yes — raw, uncured urushi lacquer (urushiol) can irritate the skin or trigger allergic reactions, much like poison ivy. Many traditional craftsmen recommend wearing gloves, long sleeves, and working in a well-ventilated space when handling uncured lacquer.

Once the lacquer is fully cured and sealed, lacquerware is generally safe for everyday use. However, if you have known sensitivities to natural resins, it’s wise to exercise caution or choose pieces that are professionally treated and clearly marked as food-safe.

Yes. Kintsugi embodies the philosophy of repair, reuse, and respect for objects. Instead of discarding broken pottery, it transforms damage into beauty, extending the life of items and reducing waste. This aligns with sustainable living ideals and adds unique historical/aesthetic value.
