Xuan paper is divided into raw Xuan, semi-cooked Xuan and cooked Xuan. Shengxuan has strong water absorption and hydrophilicity, and it is easy to produce rich Mo Yun changes. By splashing and accumulating ink, water can be collected and diluted to achieve the artistic effect of water flow. Used for freehand brushwork. It is this "changeable" interest in ink that the winning candidate pursues in painting. When he puts pen to paper, it will be decided, and the ink will permeate quickly, which is difficult for unskilled people to master. It is this magical variability that has attracted countless celebrities and masters to make unremitting exploration in the pursuit of Mo Yun and change. The phenomenon that water droplets gradually spread around raw Xuan is called wet dyeing characteristics. Raw Xuan has strong wet dyeing properties, and different raw Xuan papers show wet dyeing properties.
Cooked Xuan is coated with alum when it is processed, so the paper is harder than raw Xuan, and its water absorption capacity is weak, and the ink color will not spread when it is used. Therefore, the characteristics make cooked propaganda suitable for meticulous painting rather than ink freehand painting. Cooked Xuan can be reprocessed. Coral, mica paper, cold gold, wine gold, glutinous golden flower tendon and peach tiger skin are all reprocessed colored papers.
Semi-cooked Xuan is also processed from raw Xuan, and its water absorption capacity is between the first two. Yu Ban Xuan belongs to this category.
The simple way to distinguish between raw propaganda and cooked propaganda is to dip paper with water. Health propaganda is the time when the water is dispersed immediately, and cooked propaganda is the time when the condensation is basically unchanged. Half-cooked propaganda (also called boiling hammer propaganda) spreads slowly.
When writing with light ink, the ink can easily penetrate and melt, and it is always easy to faint. So it is relatively easy to write in thick ink. Therefore, when creating calligraphy and painting, you need to master the shade of ink to be handy. This wet dyeing property of Shengxuan is applied to calligraphy creation. After the writer has a strong writing skill and can well drive the wet dyeing of ink, he can use the four-way overflow characteristic of ink falling into paper to turn the ink into it. In this way, the ink left on the surface of the paper penetrates into the inside of the paper. When the writer practices skillful writing skills, the winning wet dyeing makes the written font full and elastic. After the work is mounted, ink and wash. Because of the unique wet dyeing of health promotion, writing becomes more and more difficult. Therefore, calligraphy practice, as a practical behavior to improve life accomplishment, needs long-term cultivation to achieve the expected goal. For wet dyeing, it can exercise the writer's inner self-restraint and self-cohesion, and it is also a way to test the writer's patience and character.
