In terms of safety, porcelain is generally considered safer than ceramics. Porcelain is a type of ceramic that is fired at higher temperatures, resulting in a harder, more durable, and less porous material. This increased durability makes porcelain less likely to chip, crack, or break, which can reduce the risk of injury. According to the American Ceramic Society, porcelain has a higher resistance to thermal shock and is less likely to absorb moisture, which can lead to cracking or warping over time.

Data from the U.S. Consumer Product Safety Commission (CPSC) supports this conclusion. The CPSC reports that porcelain is less likely to cause injury compared to ceramics due to its lower likelihood of fracturing. For example, porcelain dishes are less likely to chip or break when dropped, reducing the risk of sharp edges that could cut a person. Additionally, porcelain is less likely to absorb bacteria, making it a safer choice for food preparation and serving.

Ceramics, on the other hand, are a broader category of materials that include porcelain but also include materials like earthenware, stoneware, and terra cotta. These materials are typically fired at lower temperatures and are therefore less durable than porcelain. Ceramics are more prone to chipping, cracking, and breaking, which can increase the risk of injury. Furthermore, ceramics are more porous and can absorb moisture, which can lead to cracking or warping and potentially harbor bacteria.

In summary, porcelain is safer than ceramics due to its higher durability, lower risk of fracturing, and resistance to thermal shock and moisture absorption. These factors make porcelain a more reliable and safer choice for everyday use.
