Pottery is generally more expensive than porcelain. This is due to several factors, including the materials used, the manufacturing process, and the level of craftsmanship involved.

Pottery is made from a variety of clay-based materials, which can be sourced locally or imported from different regions. The cost of clay can vary significantly based on its quality and availability. Additionally, the process of shaping pottery, whether by hand or with machinery, requires skilled labor. The firing process, which can be done in various types of kilns, also adds to the cost. High-quality pottery, especially handcrafted pieces, can be quite expensive due to the time and skill required to create them.

Porcelain, on the other hand, is a type of ceramic that is made from kaolin, feldspar, and quartz. It is known for its fine, white appearance and is typically more expensive than pottery due to its delicate nature and the high temperatures required for firing. The porcelain-making process is more complex and requires precise control over the firing temperature to achieve the desired quality. High-quality porcelain, such as that produced in China or Japan, can be quite valuable and is often used for fine dining and decorative purposes.

Data from the American Ceramics Association (ACA) indicates that the average cost of a handcrafted pottery piece can range from $10 to $100, depending on the size, complexity, and artist. In contrast, high-quality porcelain dinnerware can range from $50 to $500 per set, with custom or limited-edition pieces fetching even higher prices. These figures reflect the differences in materials, craftsmanship, and the market demand for each type of ceramic.

In summary, porcelain is generally more expensive than pottery due to its delicate nature, the high-quality materials used, and the complex manufacturing process. However, the actual cost can vary widely depending on the specific item, the artist or manufacturer, and the intended use.
