Composition Variations
Porcelain differs from China clay by including additional elements such as feldspar and quartz that give its unique properties, similar to how adding eggs and sugar turns flour into cake batter.
Manufacturing Process
China Clay Extraction
Extracting china clay can be like mining for treasure: quarrying, refining and processing the raw material until we achieve pure white clay for various uses.
Porcelain Production
Porcelain production on the other hand is like making art; carefully mixing ingredients, shaping the mixture and firing at high temperatures are required in order to produce that beautiful glossy surface.
Practical Applications
China Clay Applications
China clay finds use in an astounding range of products. It can give paper an attractive sheen while improving paint opacity or serving as filler in medicines; making China clay one of the secret ingredients behind our everyday items we depend on every day.
