Distinguishing method:
1, look. This is the most common and direct method. There will be many bright reflections on cooked rice paper, called alum. Because of it, the cooked rice paper will not leak. Although it is thin, it can be colored many times. Raw rice paper looks more like ordinary paper, without bright reflection.
2, use: health promotion. Strong ink absorption, the edge will show different effects due to different paper quality after inking (good raw rice paper has regular ink marks on the edge and beautiful waterline, while bad raw rice paper will be full of ink). So you can use water drops on paper, and it is raw rice paper that spreads quickly around.
3, use: cooked publicity. Cooked rice paper can be colored repeatedly, without alum leakage, and it looks waterproof. Therefore, dropping a drop of water on the cooked rice paper will keep the shape (it will not be absorbed by the paper immediately, and the water will dry after a long time).
4. Usage of raw rice paper and cooked rice paper in painting: When painting, raw rice paper is often used for freehand brushwork (often used for painting landscape paintings and heroic paintings). Cooked rice paper is often used for meticulous painting (flowers and birds, figures, buildings and other works with many details).
