Classification of Yixing Zisha Pottery

The modeling of purple sand ware is mainly divided into three categories: geometric shape, natural shape and ribbed shape. It was created by the artists of Zisha in the past dynasties who carefully observed and studied the shapes of various utensils and absorbed the artistic characteristics of traditional handicrafts in China.

Geometric shapes are divided into two types: round and square. Both shapes are decorated with geometric lines, and even some shapes are geometric figures themselves. The modeling feature of the rib device is that the top view of the car body is divided into several equal parts, and the vivid and smooth ribs are organized in a precise and strict structure. This is the modeling style created by melon ridges, petals, clouds and water lines seen in life. Therefore, the choice of rib device not only seeks changes in the side view of modeling, but also has a more attractive image in the top view. Rib pattern device has clear and smooth texture and tight seam covering, which is a high integration of art and technology. The shape of the ribbed container was developed on the basis of the early hexagonal pot of sand ware. The modeling rules of rib pot art are "correspondence from top to bottom, consistent body cover, harmonious shape, accurate proportion, clear texture, free depth, clear light and shade, and reasonable configuration". Most of this kind of pot art requires that the spout, lid, spout, handle and handle must be ribbed to match the texture of the pot body. This also makes the requirements of pot art and the combination of pot body and pot cover become precise machinery. Every equal part, every spout semicircle, arc and so on must be calculated very accurately. The rigor of its technical methods has reached an unparalleled degree of rigor. In modern times, the common shapes of ribbed devices include diamond-shaped pots and semi-chrysanthemum pots.

These modeling types of teapots include almost all creative forms in nature and the world. This is also an important reason why the shape of purple sand ware is particularly rich. Some casserole has two or even three shapes. This modeling method is to decorate other shapes on round and square pots. For example, the ball pot is a combination of natural shape and geometric shape; Square bamboo pots are not only prismatic, but also geometric and natural. Hexagonal spherical tank is the fusion of natural shape, geometric shape and ribbed shape.

Various shapes of purple sand ware are developed on the basis of square ware and round ware. Therefore, the shape of the purple sand ware is "square and round."
