: 1. Cooked rice paper is a deep-processed product of raw rice paper, which is made by adding gum alum to raw rice paper. Cooked rice paper is convenient to process, simple to make and easy to master. The key to making cooked rice paper is the preparation of rubber alum.
2. Glue can be bone glue or peach glue. Alum is alum, so it is advisable to use edible alum with high purity, no impurities and good transparency. The proportion of rubber alum is very important. The weight of rubber alum is light, the paper is not easy to cook, there will be leakage of alum, and it will not stand many stains.
3. Glue is lighter than alum, paper is brittle and inflexible, easy to break and can't wrinkle, which not only affects the life of paper, but also is not easy to use.
4. The proportion of glue and alum depends on painting requirements and paper quality, and there is no absolute standard. Different viscosity of glue and different proportion of alum will directly affect the production effect.
