kintsugi Restoration

金継ぎ

Kintsugi, meaning gold mending in Japanese, is a Japanese art and craft technique of restoring broken ceramics with traditionally with Urushi tree lacquer as a glue and gold powder as a decoration on those broken lines. Even though Urushi lacquer has been used as a natural glue for over 9,000 years and restoring vessels for over 6,000-7,000 years in Japan, Kintsugi became an art form in the 15th century among the tea ceremony culture. Known as the Japanese aesthetic of Wabi-Sabi, an appreciation of beauty in imperfection and impermanence, Kintsugi gives us the opportunities to accept the natural changes in our life.

I take commission work in my Portland, Oregon home studio.

Whether it is a family heirloom dish that passed on to the generation to generation, a sentimental little cup that your 10 years old child made for you for a mother’s day, a mug cup your father used to drink coffee every morning… whatever the story behind is, I honor and respect each client’s wish to restore their special pieces. Please use the inquiry form below and show me what you are wishing to restore. I will get back to you as soon as possible with a rough fee and time estimate.

Kintsugi basics

I would like to introduce you two different methods of Kintsugi restoration. It is important for you to understand the differences and your intention of restoring your special vessel before contacting me. Please ask me any questions you might have.

Traditional (food safe) - In this method, I use all natural materials such as Urushi tree lacquer, wheat flour, stone powder, tree sawdust , water, real gold or silver powder. It takes a few months to finish a project because Urushi lacquer takes several days to cure and harden. The process is complex and very detail oriented. The vessel will be food safe and you can use it to eat and drink out of it after 2 months of rest period. NO MICROWAVE. NO DISHWASHER. Please use very soft dishwashing sponge to handwashing's the vessel. When you serve a temperature hot food/drink, warm up the vessel first to avoid the shock. The temperature shock will leads to leaks and breakage. You cannot use it over the fire to cook since Urushi lacquer will not tolerate the high temperature. Please hold the bottom of the mug if the handle was restored so that the stress on the handle can be distributed to avoid breakage go the repair.

Modern (NOT food safe, Display purpose only) - In this method, I use Epoxy glue, Epoxy putty, imitation gold, copper, cashew nut base resin materials and other resin materials. The process is faster because resin materials dry quickly but the restoration work could be as complicated as the traditional. The finished piece is only for display. Please do not eat or drink out of it.

Me & Half Ripe studio

Hi I’m Ayumi Hill of the Half Ripe Studio based in Portland, Oregon. Ever since I learned to practice Kintsugi in 2023, I’ve never felt bad when I break something in my kitchen. In my mind, Yes! another project that I can do Kintsugi and give an even better and unique look to this piece. I am in love with the Kintsugi philosophy and the process.

I am a Japanese native from Saitama prefecture and have been living in the US for 30 years. Portland , Oregon has been my home since 2005. I started Kintsugi in December 2023 by taking Emi Joyce’s classes and have been pursuing my passion to get better at it ever since. I named my Kintsugi studio, Half Ripe by getting an idea from my name Ayumi. The Kanji character 歩実 means “grow into a fruit” Fruit represent a maturity and my goal. As the name suggests, I always want to be learning and growing. Kintsugi gives me the perfect opportunities to be in the state of mind.

  • No worries :) Most of the time, I use putty and fill the missing areas. It takes more work and time to complete those projects.

  • Urushi tree belongs to the same tree family as poison oak. When the lacquer is not fully cured, it could make some people miserable with skin rashes. I always wear gloves when I practice so avoid rashes. I advise my clients not to touch and use the finished vessels for 2 months especially for food consumption just to be safe.

  • I prefer in person drop off/pick up at my home studio in NE Portland, OR. But if you have to mail the vessel, I advise wrapping it very carefully so that it will not break even more. I will ship it back with my most careful way to packing. You can use Fedex, UPS, USPS, etc of your choice of shipping company. Please be aware that I will include the cost for shipping and special packing materials in some cases in the invoice.

  • Please use the form below to contact me with your name, email address, a brief description of your project including approximate measurements. Most importantly upload pictures. I will get back to you as soon as I can!

  • It depends on the material choices(food safe or not), size of the vessel, how many broken pieces, what’s made out of (ceramic, porcelain, glass, etc), surface texture, ceramic glaze types, how much missing areas to be filled and so on… I would say $100 and up is quite normal pricing to start out just to give you an idea.

  • Yes, even if you are careful and follow my direction what to do and not to do, the vessel can leak water in the future and gold finish could start to rub off. If there is any issue, please contact me and I’ll be happy to take a look and see if I can do anything for you. There might be a case which you might need to let it be a display piece to enjoy it.

  • I mainly take cash or Venmo. If you need another method, please let me know. Any project over $200 requires a deposit of half the fee estimate.

  • DO wait for 2 months to use the traditional food safe Kintsugi work restored with Urushi lacquer to avoid possible allergic reaction in case it is cured immaturely.

    DO use very soft dish sponge to clean after use.

    DO warm up the vessel before putting hot drink or food. Temperature shock could lead to the failure of the restoration.

    DO appreciate the nature of Kintsugi with Urushi lacquer. Urushi can be absorbed and stain some of the glaze even with the careful application and masking method. It is the sign of the true Kintsugi work with the natural materials.

    DON’T put it in a microwave!

    DON’T put it in a dishwasher!

    DON’T use anything hard to scratch the gold: Metal utensils, coarse dish sponge.
