How to Make a Natural Version of Super Glue (Gum Arabic Glue)

Believe it or not, you can make your own version of super glue at home, and it works pretty well, with just a few ingredients. This is a gum arabic glue, which works like superglue, but not quite as well (more on this later).

This homemade glue is designed to mend broken china and crockery. It really does work for that purpose. To make it at home, you just need to make sure you have some Gum Arabic and some glycerine.

What This Glue Is Best For

Gum arabic glue is a good fit for small, clean breaks in china, porcelain, and light crockery. It works best when the broken edges match up neatly and there are no missing chips. Think of a saucer snapped in two, a small decorative dish, or a teacup handle that broke cleanly.

NOTE: It’s not the right glue for heavy repairs, load-bearing pieces, outdoor items, or anything that will be soaked often. It also isn’t ideal for pieces that go in the dishwasher, microwave, or oven. Heat and water can weaken natural glues over time.

This glue is especially useful for decorative pieces that you still want to handle gently. If the repaired item has sentimental value, this can be a simple home repair before deciding whether it needs professional restoration.

Gum Arabic Glue Is Not the Same as Store-Bought Superglue

I said above it works not quite as well as store bought super glue, and here’s what I meant by that. Store-bought superglue is made of cyanoacrylate. This is a chemical that bonds fast, dries hard, and is stronger than most glues on many non-porous surfaces.

Gum arabic glue is different. It is a natural glue made from hardened tree sap, usually from acacia trees. It dries into a firm, clear bond, but it is not as water-resistant or heat-resistant as modern superglue.

So when we call this homemade version “superglue”, what we’re saying it that it works a lot like the store bought. Meaning, you apply a very thin layer to both broken edges, press the pieces together, and hold them until the bond sets. But the chemistry of the glue is different, and the artificial ingredients are more powerful.

This homemade version is still great. Just don’t expect it to do everything store bought superglue can do.

Choosing the Right Gum Arabic

Gum arabic is sold in a few forms. Powder is the easiest to use for this recipe because it mixes faster and gives a smoother glue. You may also see it sold as crystals or lumps. Those can work too, but they take longer to dissolve and may need to be crushed first.

Look for plain gum arabic with no added color, flavor, sugar, or fragrance. Craft-grade gum arabic should be fine for decorative repairs. Food-grade gum arabic is a better choice if you’re repairing something that may touch food.

Anything labeled “gum arabic solution” might contain preservatives or additives that may change the texture of the glue, so avoid those.

Getting the Best Bond

The most important part of using this glue in repair is surface prep. The broken edges should be clean, dry, and free from grease. Even a little oil from your fingers can make glue less effective.

Wipe the broken edges with a barely damp cloth and let them dry fully. For greasy pieces, a tiny bit of mild dish soap can help, but rinse well and let everything dry before applying glue.

Test fit the broken pieces before you add glue. The pieces should come together smoothly without rocking or sliding around. If tiny crumbs of ceramic are stuck on the break, gently brush them away with a dry toothbrush.

Apply the glue very thinly. A thick layer will not make the repair stronger – it just makes the joint messier and slower to dry. A matchstick, toothpick, or small artist brush works well.

Clamping and Holding the Piece

Be sure to hold the repair firmly while it dries. For small pieces, your fingers may be enough. For awkward shapes, you can use masking tape, painter’s tape, rubber bands, or a soft cloth tied around the piece can help.

Be careful not to use enough pressure to shift the piece out of place. If glue squeezes out from the seam, wipe it gently with a damp cotton swab before it dries.

Set the repaired piece somewhere safe while it cures. I usually put the item on a folded towel on a table or floor. Make sure pets, kids, and curious adults won’t bump it.

Food Safety and Everyday Use

Gum arabic itself is used in some foods, but that doesn’t necessarily mean every homemade glue repair is food-safe. The safety depends on the grade of gum arabic, the cleanliness of the repair, the glycerine used, and how the item will be used later.

For the safest approach, use this glue on decorative pieces or areas that do not touch food or drink. If you mend a plate, avoid using it for hot, wet, or acidic foods. If you mend a cup, do not use it for boiling-hot drinks.

Hand wash repaired pieces gently and dry them right away. Don’t soak them or scrub the seam. And don’t put repaired dishes in the dishwasher. That will break down the bond.

How to Store the Glue

Keep the finished glue in a small airtight container. A little glass jar with a tight lid works well. If you use a plastic container, choose one that seals firmly and is easy to clean.

Label the jar with the date you made it. The glue can keep for about a year, but it is worth checking before each use. If it smells odd, grows mold, changes color, or separates in a way that stirring does not fix, throw it out and make a fresh batch.

Store it in a cool, dry cabinet away from sunlight. You do not need to refrigerate it, and refrigeration may make it thicker. If it thickens slightly over time, stir it well. If needed, add water one drop at a time until it reaches a workable texture again.

Fixing Common Problems

If the glue is too thick, add a tiny amount of water and stir well. Go slowly. A few drops can change the texture quickly.

If the glue is too thin, add a little more gum arabic and let it sit for a few minutes before stirring again. Powder needs time to absorb moisture.

If the repair will not hold, the surface may be dirty, the coat may be too thick, or the pieces may not be making close contact. Clean the edges and try again with a thinner layer.

If dried glue shows along the seam, soften it with a damp cotton swab and wipe gently. Do this carefully, because too much water near the seam can weaken a fresh repair.

To use: dip a matchstick into it to apply a very thin coat of it to both sides of broken crockery, and then fit the pieces together. As you would do with Superglue, hold the pieces firmly together until the glue dries. That could take up to an hour.

Let it dry at least twenty-four hours before you use or wash the mended piece. That way you’ll get a good strong bond that should last a long time.

Two amazing features of this glue are that it doesn’t need any cooking and it will keep for a year before going off.
