What is kintsugi?

Kintsugi is the Japanese art of mending broken pottery with gold. The broken pieces are first put back together using Japanese lacquer, also called “urushi.” The lacquer is then dusted with gold powder. It is estimated that the kintsugi repair technique was developed during the Muromachi period (1336–1573 CE). At the time, the art of kintsugi was often used to repair ceramics used in the tea ceremony.

Rather than hiding the cracks, kintsugi highlights them with gold. Items repaired with kintsugi become more precious than before they were broken and they can even turn into real pieces of art.

What is urushi lacquer ?

Urushi lacquer is refined sap that is extracted from urushi trees, which can be found in Japan and China. This sap is known for its adhesive properties and it is widely used in Japanese traditional lacquer craft. Unlike chemical resins such as epoxy, urushi lacquer is completely natural and food-safe.

How long does it take to repair an item with kintsugi ?

Depending on the number of coats you apply and the environment you find yourself in, the time needed to dry the urushi lacquer can greatly vary. One layer usually takes 1 to 2 weeks to dry completely. Therefore, it is very common to take 3 months to complete a kintsugi restoration project.

What are the optimal conditions for urushi lacquer to dry ?

Urushi lacquer is a living material that is heavily affected by its environment. Optimal conditions to have urushi lacquer dry would be 20~25℃ (68-77F) and humidity being around 70~80%. In order to create optimal conditions for urushi to dry, you can create a Urushi Box. Please watch our explanational video for more ifnormation: https://www.youtube.com/watch?v=ouDCBSd92FA

Are TSUGUKITs food-safe ?

The TSUGUKITs "Gold Only" and "Traditional" are completely food-safe.

The only ingredient that is not certified food-safe amongst our products is the alternative metallic powder provided in the TSUGUKIT "Practise." For safety, we recommend using it for decorative items. Since this finishing powder is cheaper than gold powder, it is ideal for practising your kintsugi skills.

What precautions should I take when doing kintsugi ?

Raw urushi lacquer is known for its capacity to cause strong allergic reactions similar to those of poison ivy when put in direct contact with the skin. Not everyone is sensitive to urushi, but we stronly recommand to use gloves and cover your arms when doing kintsugi. You can also wear safety goggles for extra safety. If you get raw urushi on your skin, please use vegetable oil and remove it before it hardens. If you have an allergic reaction, please soak the affected skin in a warm salt bath, it will help relieve the itchiness.

Please note that TSUGU TSUGU is not responsible for allergic reactions caused by the urushi lacquer provided in our TSUGUKITs.

Should you have an allergic reaction when using urushi, please contact immediately your physician.

Objects repaired with urushi lacquer are used once the lacquer is completely dry. When completely dry, urushi lacquer does not cause allergic reactions.

How should I care for objects repaired with kintsugi ?

Items repaired using traditional kintsugi techniques should be treated with the same care as traditional lacquerware.
Please note the following:
1. Fractured points repaired with urushi lacquer become stronger as time passes. It is recommended that you start using the item 3-4 months after it was repaired.
2. Do not place an item repaired with kintsugi in a microwave, a dishwasher, an oven or an open fire.
3. Always wash by hand. Make sure to wash your repaired item gently and avoid scrubbing around the repaired cracks.
4. Be careful not to scratch the repaired parts when using sharp cutlery such as forks and knives.
5. Please make sure that the parts repaired with urushi lacquer are not damaged by other plates and cups when storing your tableware on your cupboard shelves.
6. Do not place the repaired item in a fridge for too long.
7. Do not soak the repaired item in water for too long.
8. Store the item in a place where it is not directly exposed to sunlight.

What should I prepare while waiting for my TSUGUKIT?

Tissues, one pair of scissors, utility knife, all-purpose flour, oil (canola or salad oil), water, additional rubber gloves, ethanol for disinfection use (+/- 70°), an urushi box (carton, wooden or plastic box which can be closed with a lid), plastic wrap and rubber bands if applicable.

How many broken items can I repair with my TSUGUKIT?

Since each broken item is different, it is hard to say precisely how many items you could repair with our kit. However, we estimate that you should be able to repair the equivalent of 5-10 broken plates with the TSUGUKIT.

If you have a lot of items to repair, be careful to not use all the gold powder in one go. Also, if you feel you need more practice, we recommend you to purchase metal powder in your country and use it instead of our genuine gold / silver powder. Please note, however, that metal powder sold in DIY stores is rarely food-safe.
