How to determine the half raw and half cooked rice paper

The simplest and most practical method (also most commonly used by calligraphers), with the tip of the tongue in the paper gently licked, if the water seeping rapidly, and the water traces outward diffusion, it is the raw Xuan; such as the water does not seeping into the paper, it is ripe Xuan. If the water is only seeping into the paper, but not to the outside, or only a small amount of slow speed to the outside, is half raw and half cooked rice paper.

Of course, if you have the conditions, it is best to use a brush dipped in water or ink to try.
