Porcelain is just one of the variations of ceramic. The family of ceramics includes earthenware, stoneware, porcelain, bone china, and others.
The main difference is that the clay used to make porcelain is refined and is hardened at higher temperature, resulting in a more resistant, yet delicate and translucent appearance.
Ceramic dinner plates are made from a mixture of clay, water, and other minerals. The clay is shaped into the desired plate shape and then dried. After that, the plate is fired in a kiln at a temperature of about 1,000 to 1,200 degrees Celsius. Ceramic dinnerware is thicker and more opaque than porcelain, and is also known for its colorful and decorative designs.
Porcelain dinner plates are made from a specific type of clay called kaolin, which is combined with feldspar and other minerals. The mixture is shaped into the desired plate shape and then fired at a higher temperature of about 1,200 to 1,400 degrees Celsius. The production of bone china is essentially the same, except for the addition of bone ash which makes tableware stronger and with a more off-white color than porcelain.
