Shengxuan refers to the raw rice paper without any processing; Cooked rice paper refers to rice paper processed by dyeing, gold sprinkling, silver sprinkling, printing, waxing, calendering and alum application, also known as processing propaganda.
Health categories include Jiagong, Jade Edition, Jiege, Shan Cuo, Lian Mian and so on. Shengxuan is unprocessed, with strong water absorption and hydrophilicity, and it is easy to produce rich Mo Yun changes. By splashing and accumulating ink, the artistic effect of collecting water, blooming ink and emphasizing color is achieved. Used for freehand brushwork. Although Sheng Xuan's paintings are full of ink interest, they are easy to master because of the rapid infiltration of ink and wash.
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.
Health promotion is highly absorbent. When writing with light ink, the ink easily penetrates and melts. 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.
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.
