Porcelain as we know, is a type of ceramic that is white, strong and transparent. This ceramic material is typically fired at a very low temperature in order for it to fully convert from green ware to bisque ware. Finally, it is then glazed and fired at a much higher temperature and thus resulting in a final product. Unlike other clay materials, porcelain does not need glazing to solidify them resistant to liquids. For the most part, they are glazed specifically to make them resistant to dirt, for staining and for decorative purposes only.
This material first originated in the years 618-907 AD in China which is how porcelain obtained its other common name “china” or “fine china”. Porcelain is made primarily from Kaolin along with other clay minerals. Kaolinite is a type of material referred as to “raw”. The types of clay used for specifically for porcelain are lower in plasticity and are typically shorter than other clays. Porcelain as opposed …show more content…

Bone china is normally made from 2 parts of bone ash, along with 1 part of kaolin and 1 part of china stone. Hard past on the other hand, is made from kaolin, feldspar and quartz. Hard paste is then fired at a low temperature which as a result, allows the porcelain to harden, allows to be become translucent and gives it great stability and strength. Lastly, soft paste is made from kaolin, feldspars, nepheline syenite along with other rocks and is fired at an even lower temperature than hard paste thus resulting it to be less hard than hard paste porcelain objects are fired. This type of soft paste was one of the first types of pastes that Europeans first used in hopes to replicate Chinese porcelain. Unfortunately, they were not very successful due to the fact that they were not using the correct mixtures of clay which resulted in deformation or slumping of their artistic
