China clay (kaolin) is an essential element in making porcelain; other applications for it include papermaking, paint production, and cosmetic use. China clay forms by weathering rocks in water environments and has a fine, particulate structure which gives its characteristic fine-grained surface finish.
Hydrous kaolin powder is a naturally occurring clay mineral composed primarily of kaolinite. It distinguishes itself from its calcined counterpart due to its fine particle size and higher water content, both features which mark its presence.
Hydrous kaolin extraction involves mining and refining clay deposits before going through several purification steps to eliminate impurities and achieve the desired properties.
