What is rice paper made of?

Bark. Xuan paper originated in Jingxian county. At first, celadon bark was the main raw material. Later, in the process of leather processing, straw was used to fill the pile feet, and it was found that it could also become white pulp. Later, straw became one of the main raw materials of rice paper. Among the straws, Jingxian high-quality Shatian long-stalk indica rice is the best, because this kind of straw is above the average level.
