Rice glue ( Japanese: 続飯, sokui) is a gel or liquid adhesive made of a smooth mush of well-cooked white rice, diluted to the desired thickness with water. [1] [2] It has been used since antiquity for various arts and crafts; for instance, it is a woodworking [1] and paper glue. [2] When dried, it is transparent. [2] Rice glue is notable for containing no acids which can degrade the materials it holds together.
It is still used in modern times to reversibly assemble joints; after it has dried, the glue can be soaked, [1] steamed, or split to re-open the joint; [1] on a small wood joint, the glue is resistant to tens of minutes of water immersion. [3]
It is sometimes mixed 1:1 with urushi lacquer to make nori-urushi (Japanese term), which is darker and dries faster than undiluted lacquer, and is used in making lacquerware. [1]
Rice glue is frequently used in Japan and in China.
