Kintsugi without real gold: what the gold in repair kits actually is

The gold in almost every modern kintsugi kit is not powdered bullion, it is a premium gold mica pigment, the same family of mineral pigment used in fine cosmetics and art materials. That is not a compromise so much as the reason the craft is available to the rest of us: real gold powder over traditional lacquer belongs to trained artisans and month-long timescales, while mica pigment mixed into a modern adhesive gives a seam with genuine metallic depth in an evening.

It is a fair question, and one we get often. If the gold is not gold, is the repair still kintsugi? Here is what is in the pot, how it compares with the traditional method, and why the answer is more interesting than a simple yes or no.

What is the gold in a kintsugi kit made of?

Mica is a naturally occurring mineral that splits into extremely fine, flat, transparent flakes. Coat those flakes and you get a pigment quite unlike ordinary paint: light passes into the layer, bounces off the platelets and comes back out, which is why mica pigments shimmer and shift with the angle you view them from. It is the optical trick behind a metallic car finish.

In our Kintsugi Repair Kit that pigment is supplied as a gold effect powder to brush along the finished seam, alongside a two part epoxy adhesive, a mixing card and applicator, two china practice bowls and the instruction booklet. Some makers prefer to stir a little of the powder into the glue itself so the vein is gold all the way through rather than gold on the surface. Both approaches work, and the kit lets you try each on the practice bowls before you commit.

What did traditional kintsugi use instead?

The traditional craft joins the broken edges with urushi, a lacquer tapped from the Japanese lacquer tree, and dusts real gold powder over the seam while it is still tacky. It is beautiful and it is slow. Each stage cures for days or weeks in a humidity controlled cabinet, and a single bowl can take a month or more of patient, repeated work.

Urushi is also demanding in a way that has nothing to do with skill. Until it is fully cured it can cause strong skin reactions, which is one reason the craft stayed in the hands of trained artisans for centuries rather than becoming a household pastime. Add the cost of gold powder measured out by the gram and you can see why kintsugi remained rare enough to feel almost mythical outside Japan.

If you fall for the craft, the old way is there waiting, and it is a genuinely lifelong pursuit. It is simply not where anybody should start.

Does mica gold actually look as good?

On opaque ceramic, honestly, yes. A mica pigment seam catches light along its length and reads as metal rather than as yellow paint, and because the flakes are fine, it follows the line of a crack closely instead of sitting on top of it as a stripe.

Where it differs from real gold is in how it ages. Gold is gold, and it will still be gold in a century. A mica seam is stable and hard wearing, but it is a coated mineral rather than a precious metal, so treat a repaired piece kindly.

The bigger influence on how a repair looks is not the pigment at all, it is your hand. More adhesive along an edge squeezes out into a bolder, thicker vein, while a sparing layer keeps the seam delicate. The line is yours to design, which is exactly why we include two bowls to practise on.

Two things reliably spoil the effect. The first is using too much glue and having to wipe it away in a hurry, which smears the join. The second is brushing powder onto a seam that has cured hard, at which point it has nothing to grip. Apply it while the seam is still slightly tacky, or run a fine extra line of adhesive along the join first.

Is a mica gold repair still real kintsugi?

Purists will tell you epoxy and mica kintsugi is not the ancient craft, and they are right on the facts. What a modern kit preserves is the idea, which was always the important part: that a break is not something to hide, that a mended object can be more beautiful than an unbroken one, and that the repair deserves to be shown in gold rather than disguised.

That idea comes from wabi-sabi, the Japanese worldview that finds beauty in imperfection and impermanence, and it does not depend on the price of the pigment. A bowl mended at a kitchen table on a Tuesday night, wobbles and all, carries the philosophy just as completely as a museum piece does.

What can you do with a repaired piece?

This is where the honest limits matter, and they come from the adhesive rather than the pigment. The epoxy is not food grade, so a repaired piece is best kept for display rather than used for food or drink. It is not waterproof either, so it is not the technique for a vase you intend to fill. And the dishwasher is off the menu permanently: dust it by hand and wipe it gently.

Within those limits there is plenty of scope. Bowls become homes for keys, rings and, our favourite, tea lights, all of the beauty with none of the food contact. Plates and ornaments go back on the shelf looking better than before the accident.

Handle the adhesive with care while you work. It is a strong glue that can bond skin in seconds, so wear the gloves, work in a well ventilated room, keep it away from children, heat and flames, and read the safety notices in the booklet before you start. No kiln, no oven and no firing are needed at any point, only time for the glue to cure fully.

If you are weighing up a first kit, the thing to look for is not the price of the pigment but whether there is something to practise on. The two bowls in the Sandy Leaf Farm Kintsugi Repair Kit exist so that your first golden seam is not also your only chance at the piece you actually care about, and it is hand-packed in Britain.

Kintsugi gold FAQs

Is the gold in a kintsugi kit real gold?

In most modern kits, including ours, it is a premium gold mica pigment rather than powdered gold. Kits using real gold exist, at many times the price and usually alongside traditional lacquer.

Will the gold seam rub off over time?

Not if it is bonded properly. Apply the powder while the seam is tacky, or over a fine extra line of adhesive, and let it cure fully. Then treat the piece as decor and it will hold.

Can I use silver or another colour instead?

The same technique works with any mica pigment, and silver seams look wonderful on darker glazes. Our kit is supplied with gold, which is the classic look.

Does the pigment make the join weaker?

Brushed along the surface of a cured seam, no. If you are mixing pigment into the epoxy, keep it to a small scoop so the two parts still mix in equal measure and cure hard, which is the single most important step in the whole repair.

Can a repaired bowl hold food or water?

No. The adhesive is not food grade and the repair is not waterproof, so repaired pieces are decorative. Tea lights, keys and dried flowers are the right sort of job for them.
