Quick Details
Specifications
Kaolin is used (or was used in the past):
-in ceramics (it is generally the main component in porcelain)
-in toothpaste
-as a light diffusing material in white incandescent light bulbs
-in cosmetics
-as paint to extend titanium dioxide (TiO2) and modify gloss levels
-for its semi-reinforcing properties in rubber
-in adhesives to modify rheology
-in the production of common smoking pipes in Europe and Asia
-in organic farming, as a spray applied to crops to deter insect damage, and in the case of apples, to prevent sun scald
-As whitewash in traditional stone masonry homes in Nepal (the most common method is to paint the upper part with white kaolin clay and the middle with red clay; the red clay may extend to the bottom, or the bottom may be painted black)
-as a filler in Edison Diamond Discs
-as an indicator in radiological dating since kaolinite can contain very small traces of uranium and thorium
-to soothe an upset stomach, similar to the way parrots (and later, humans) in South America originally used it (more recently, industrially-produced kaolinite preparations were common for treatment of diarrhea; the most common of these was kaopectate, which abandoned the use of kaolin in favor of attapulgite and then (in the United States) bismuth subsalicylate (the active ingredient in Pepto-Bismol))
-for facial masks or soap
-as adsorbents in water and wastewater treatment
-to induce blood clotting in diagnostic procedures, e.g. Kaolin clotting time
