Rice Glue is a gel or liquid adhesive made from rice and water. It has been used since antiquity for various arts and crafts such as wood working. Rice glue is notable for containing no acids which can degrade the materials it holds together. It is also still used in modern times when individuals require a joint that can be taken apart after it has dried. Rice glue is made by simmering rice in water.
