Why not recommend water-writing cloth?

First, writing with water is different from writing with ink. Ink is thicker than water, and it is frivolous without a sense of calmness. Second, the water-writing cloth dries fast, which is incomparable, in order to improve day by day. Third, water and water cloth feel that they will dry up in a short time without leaving traces, and there is no formal piety in using pen and ink.

Water-writing cloth is made according to the principle that pigment is transparent when it meets water. Generally speaking, water-writing cloth is made of black flannel with a layer of environmentally friendly white paint on the surface. This kind of paint has a special function, that is, it becomes transparent when it meets water. The main component of paint is silicon dioxide, which is the main component of sand and the main raw material for making water cups. Transparency in water is mainly due to the reflection of light.

Because we don't use ink and rice paper, writing on water book cloth has no ink resistance, and the written calligraphy works can't be preserved as long as writing on rice paper with ink. The cloth of water-writing cloth is generally flannel, but there are also three or six kinds of flannel, and Oxford cloth will use better water-writing cloth. This kind of writing cloth is more reliable. If it is just a calligraphy exercise, it is ok to write for fun at ordinary times, but if you really want to create, you still need to write on Xuan paper and other materials with a brush dipped in ink.
