What are the differences between ceramic, Bone China and porcelain?
Each raw material has a special meaning for the value of the porcelain mass. A high proportion of kaolin is a requirement for the whiteness of the sherds, quartz is responsible for the strength of the shapes and the necessary transparency is achieved by the addition of feldspar.
A small material science
Porcelain, even soft porcelain is the most common of all porcelain types. Basically, porcelain has a dense sherds and a high hardness. It is acid and alkali resistant, tasteless and a poor conductor of heat.
Bone China has a high content of calcium oxide and calcium phosphate, giving it extra transparency and lightness. Bone China is considered particularly high quality. It should be remembered that because of the thin sherds, drinks get cold faster, which is why the Italian prefers to enjoy his espresso made from particularly hard and thick sherds. Finally, the taste decides.
Ceramic is a porous earthenware, which is why ceramic products are provided with a waterproof hard glaze. This glaze would stick on firing, so that the foot usually has no glaze. Care should therefore be taken when using the dishwasher and microwave, as water and extreme heat can damage to glazing.
