A kintsugi kit is an adults only craft kit, and the reason is the adhesive. Two part epoxy is a strong glue that can bond skin in seconds, so the sensible precautions are simple and non negotiable: work in a well ventilated room, wear the gloves, avoid skin and eye contact, keep the kit away from children, heat and flames, and read the safety notices in the booklet before you open anything. Broken pottery and glass bring their own hazards, and those are worth as much thought as the glue.
None of this makes kintsugi a risky hobby. It makes it one you set up properly, the same way you would set up a table before using a craft knife.
Why is a kintsugi kit adults only?
Because of the epoxy, not the concept. The two parts are supplied separately and do nothing until they are mixed, but once combined the adhesive is designed to form a permanent bond, and skin is a surface like any other. It can bond fingers together very quickly, and it is an irritant if it gets in the eyes.
The secondary reason is the material you are repairing. Handling broken pottery or glass calls for judgement about where the sharp edges are and how hard to press, which is not a job for young hands. Children can absolutely admire the finished bowl, and it is a lovely thing to explain to them, but the making is for adults.
Working safely with the epoxy
- Ventilate. Open a window or work in an airy room. Not a cupboard, not a car, not a small bathroom.
- Wear the gloves. They are in our kintsugi kit for a reason, and putting them on before you squeeze anything out is far easier than putting them on afterwards.
- Protect the surface. Cured epoxy on a kitchen table is permanent. Lay down a tea towel, a sheet of kitchen roll or an old newspaper.
- Keep it away from your face. Avoid eye contact, do not rub your eyes with a gloved hand, and keep food and drink off the work table while you are mixing.
- Wipe spills promptly. Excess adhesive is easy to remove while it is soft and effectively impossible once it has cured hard.
- Mix on the card, not on a plate. The mixing card is disposable, so nothing that has touched adhesive goes back into the kitchen cupboard.
- Read the pack. The booklet carries the full safety notices, and if anything does go wrong, that is what you follow rather than guesswork from the internet.
If adhesive does reach your skin, follow the guidance in the booklet and on the pack. For anything involving the eyes, or skin that has genuinely bonded, get medical advice rather than pulling at it.
Handling the broken pieces
The glue tends to get all the attention, but a shattered bowl on a kitchen table is the more immediate hazard.
Lay the fragments out on a light coloured tea towel, which makes small slivers visible and stops them skating off the edge of the table. Keep the gloves on while you dry fit. When you have finished, fold the towel inwards rather than brushing debris off with a hand, and wrap any unused shards in paper before they go in the bin.
Glass deserves extra respect. Broken glass produces fine, nearly invisible splinters that pottery does not, so work slowly, sweep and wipe the area thoroughly afterwards and check the floor as well as the table. Thin porcelain is sharper than it looks too, especially along a fresh break.
Storing the kit between projects
Seal the tubes tightly after use, wipe the outside of them and keep the kit somewhere cool, dry and dark, away from children, heat and flames. Stored like that, the unmixed adhesive waits patiently for the next breakage, which in most households is not a long wait.
Keep the gold effect mica pigment sealed too, since it is a fine powder that goes everywhere if it is knocked over. And keep the whole box out of reach rather than in the drawer where the sticky tape lives, because a kit that looks like stationery is a kit a child will open.
Is the finished piece safe to use?
It is safe to have and to handle, but its job has changed. The adhesive is not food grade, so a repaired piece is decorative from now on rather than something you eat or drink from. It is also not waterproof, so it should not hold water, sit in a washing up bowl or go through the dishwasher. Wipe or dust it gently by hand instead.
That still leaves plenty of uses. A mended bowl is an excellent home for keys, rings, hairpins or a tea light in its own metal cup, and a mended plate looks better on a shelf or a wall than it ever did in a cupboard. Keep repaired pieces away from direct heat and out of the oven, since nothing about the repair is designed to be warmed.
A sensible setup, start to finish
Clear the table, lay a towel, open a window. Put the fragments out and dry fit them with the gloves on. Decide your order of assembly before anything is opened. Mix equal amounts of the two parts thoroughly on the card, spread a thin even layer with the spreader, press the pieces together and hold each join for 30 to 60 seconds. Wipe away anything that squeezes out straight away. Leave the piece undisturbed to cure fully, somewhere the cat cannot get to it.
Then tidy properly: fold the towel in, bin the card and the gloves, wash your hands, and check the floor for splinters before anyone comes in barefoot. It takes five minutes and it is the difference between a good evening and an annoying one.
Kintsugi kit safety FAQs
Is a kintsugi kit safe to use at home?
Yes, with the ordinary precautions for a strong adhesive. Work in a ventilated room, wear the gloves, protect the table, avoid skin and eye contact and read the safety notices in the booklet first.
What age is a kintsugi kit suitable for?
Adults only. The epoxy is a strong adhesive that can bond skin in seconds, and handling broken pottery or glass is not a job for children.
Do I need a mask or special ventilation?
No, an open window or an airy room is what the kit asks for. Follow the notices on the pack, which are the authority on how the adhesive should be handled.
What do I do if the glue gets on my skin?
Follow the guidance in the booklet and on the pack rather than improvising. If it involves your eyes, or fingers that have genuinely bonded, get medical advice instead of pulling at it.
Can I use a repaired bowl for candles?
A tea light in its own metal cup is a good use for a mended bowl, and a popular one. Keep repaired pieces away from direct heat otherwise, and never put one in an oven.
How should I store the kit afterwards?
Seal the tubes, keep everything cool, dry and out of reach of children, and away from heat and flames. Stored properly, the kit is ready whenever the next thing falls off a shelf.
