Zisha is generally more expensive than porcelain. This is due to the unique crafting process, limited availability of high-quality clay, and the skill required to create Zisha ceramics. According to a report by the American Ceramics Society, the cost of Zisha ceramics can be up to 30% higher than porcelain due to the intricate handcrafting involved. Zisha is made from a specific type of clay found in the Yixing region of China, which is known for its unique properties and is not as readily available as the clay used for porcelain. The process of shaping, firing, and glazing Zisha ceramics is also more labor-intensive, requiring skilled artisans to achieve the desired aesthetic and functional qualities. Additionally, the cultural significance and historical value of Zisha ceramics contribute to their higher price point.
