Shuxuan (literally "Ripe Xuan"), however, has Potassium alum worked into it during production, which results in a stiffer texture, a reduced ability to absorb water, and less resistance to shear stress (meaning that it can be torn much more easily). This feature makes Shuxuan more suitable for Gongbi (工笔/traditional Chinese realistic painting/claborate-style painting), rather than Xieyi. This item is also good for fineline script(小楷/regular script in small characters).
