Porcelain is a type of ceramic material renowned for its high whiteness, density, and low porosity. Chemically, it is a fine-grained silicate material primarily composed of kaolinite clay, feldspar, and quartz, fired at extremely high temperatures. The vitrification process during firing causes the material to become non-porous, resulting in a durable and relatively waterproof substance. From a technological standpoint, porcelain is valuable in various applications, including plumbing fixtures, electrical insulators, and dental components, because of its combination of mechanical strength and chemical inertness.
