First of all, Zisha pottery works show unique artistic concepts and forms of expression. At present, there are some differences between Yixing Zisha pottery and Qinzhou Ni Xing pottery. Secondly, Yixing purple sand pottery is mainly made of patting barrels and embedding mud. Because of its unique technology and great difficulty, it needs long-term training to master it skillfully. Therefore, it takes a relatively long time to make a good pot, and the shape of the pot is also comprehensive, such as square, round, flower-shaped, ribbed and so on. Nixing pottery in Qinzhou mainly takes blank drawing as the molding process, and the production speed is fast. However, due to the limitation of the blank drawing, only a circle can be made.
