You will often hear the term *china* and/or *porcelain* used interchangeably to refer to many types of tableware, but there are major differences between fine bone china and porcelain. What are they? Fine bone china is translucent, its clay body is white and, while still strong, it is more fragile than porcelain.
Porcelain is also a champ at shrugging off water. It may sound simple, but a porous material will allow liquid and bacteria in, so being impervious to both is important in a structure that's main job is to deal with waste. The key to keeping water out is in the porcelain's glaze. After the toilet is coated, it's fired in a kiln. Unlike, say, grout in a shower, which takes on both water and bacteria, the glaze stops bacteria at the toilet's surface.
