Rice glue facts for kids
Rice glue is a special kind of glue made from cooked white rice and water. It's like a smooth paste or a thick liquid. People have used this natural glue for a very long time, especially for arts, crafts, and even woodworking. When it dries, rice glue becomes clear, so you can't easily see it.
One cool thing about rice glue is that it doesn't have any acids. This means it won't damage or break down the materials it sticks together over time, which is great for old or delicate items.

What is Rice Glue?
Rice glue is a simple, natural adhesive. It's made by cooking white rice until it's very soft and mushy. Then, you mix it with water until it reaches the right thickness. It can be a thick gel or a thinner liquid, depending on what it's used for.
How is it Made?
Making rice glue is quite easy! You just need white rice and water.
- First, cook the rice until it's very soft, almost like a porridge.
- Then, mash the cooked rice until it's a smooth paste.
- Finally, add water slowly and mix well until it's the right consistency for gluing.
Why is Rice Glue Special?
Rice glue has some unique features that make it useful, even today.
Gentle on Materials
Unlike some modern glues, rice glue does not contain acids. Acids can sometimes harm paper, fabric, or wood over many years. Because rice glue is acid-free, it's a safe choice for old books, important documents, or delicate artwork. It helps keep things in good condition for a long time.
Reversible Gluing
One of the most interesting things about rice glue is that it's "reversible." This means that after it dries, you can undo the glue joint without damaging the materials. If you need to separate two pieces glued with rice glue, you can often:
- Soak them in water.
- Use steam.
- Gently split the joint apart.
This feature is very helpful for repairing old items or for projects where you might need to take things apart later. For example, in woodworking, if a joint needs to be fixed, the rice glue can be softened to open it up.
Where is Rice Glue Used?
Rice glue has been used for centuries, especially in countries like Japan and China.
Traditional Crafts
In the past, rice glue was a common choice for many traditional crafts. It was used for:
- Paper crafts: Like making traditional screens, lanterns, or repairing old scrolls.
- Woodworking: For joining pieces of wood, especially in furniture or art pieces.
- Bookbinding: To hold pages and covers together.
Modern Uses
Even with all the new glues available today, rice glue is still used for certain things:
- Restoration: Experts who restore old art, furniture, or documents often use rice glue because it's gentle and reversible.
- Lacquerware: In Japan, rice glue is sometimes mixed with a special tree sap called urushi lacquer. This mixture, called nori-urushi, is used to make beautiful, shiny lacquerware items. It helps the lacquer dry faster and gives it a darker color.
Rice glue is a great example of how simple, natural materials can be incredibly useful and long-lasting!
