In the debate of porcelain versus white clay, porcelain is generally considered the superior material. Porcelain is a type of ceramic that is known for its high strength, translucency, and fine texture. It is fired at higher temperatures than white clay, which results in a more durable and vitreous product. White clay, on the other hand, is a type of earthenware that is less durable and less translucent than porcelain.

Data from the American Ceramic Society indicates that porcelain has a higher thermal shock resistance than white clay. Porcelain can withstand rapid temperature changes without cracking or breaking, making it ideal for use in kitchenware and tableware. Additionally, porcelain has a lower water absorption rate, which means it is less likely to stain or crack over time. According to a study published in the Journal of the American Ceramic Society, porcelain has a water absorption rate of less than 1%, while white clay can have an absorption rate of up to 10%.

The aesthetic qualities of porcelain also make it a preferred choice. Porcelain is available in a wide range of colors and finishes, and it can be glazed to create a glossy, durable surface. White clay, while also available in various colors, typically has a more rustic appearance and is less versatile in terms of glazing options.

In summary, porcelain is better than white clay due to its superior durability, thermal shock resistance, lower water absorption rate, and aesthetic versatility. These characteristics make porcelain a more practical and visually appealing choice for a wide range of applications.
