What characterizes true porcelain compared to other ceramics?

True porcelain is characterized by its distinct composition and method of production, which typically follows a specific historical recipe involving kaolin, feldspar, and quartz. The precise balance of these materials, along with the high firing temperatures that porcelain requires, contributes to its properties, such as high strength, translucency, and low porosity. In contrast to other ceramics, true porcelain is known for its exceptional durability and ability to withstand both high heat and thermal shock, setting it apart from earthenware or stoneware, which may not possess the same characteristics.

The other options do not accurately describe porcelain's defining features. For example, true porcelain is notably less porous than most other ceramics, making it suitable for various applications, including tableware and art objects. Furthermore, true porcelain is generally recognized for being thinner and lighter than many thick, heavy ceramics. Lastly, its ability to withstand high heat is one of its hallmark qualities, allowing it to be used in a range of high-temperature applications without loss of structural integrity.
