Many times people are confused about the use of these terms and their differences; in fact they are all kinds of traditional ceramics. They are all made of alkaline clay. There are other subcategories of these three ceramics, please read on.
Differences are made when different clay compositions are used at different firing temperatures and the porosity obtained after firing. Remember that the raw clay material will dissolve in the water if it does not burn!
- As the name implies, bone china has an asbestos component mainly composed of cattle, which has been burned and pulverized into fine powder. It is highly regarded because it is the most expensive and of the highest quality. It is known for its appearance and is often referred to as "China." The ashes compound gives it a translucent and white appearance. It is obtained by firing at very high temperatures. The water absorption rate is 0%.
- Porcelain is similar to bone china, but because it does not contain ashes, it is not transparent and therefore cheaper than bone china. It is ideal for use in microwave ovens and traditional ovens. The water absorption rate is 0 to 1%.
- Pottery is the cheapest form of all types of ceramics. Since it is fired at a low temperature, it has a high water absorption rate and is therefore not as strong as other varieties. However, due to their absorptive capacity, they can be easily painted beautifully. If used for food, it is hand-decorated and glazed. Iron and dolomite are two quality variations in pottery.
- The Stone is the strongest. Because it has a higher percentage of porcelain than pottery, it is non-porous. It can be easily used in microwave ovens and is cheaper than bone china and porcelain.
