Kaolin (china clay) is a hydrated aluminum silicate derived from the mineral Kaolinite. Kaolin is chemically inert clay with a low shrink-swell capacity, well-suited to a wide range of industrial uses including ceramics, paper, glass fiber, filler, paints, wire and cable and plastics.
Ceramics: Ball clays are used in many different industries, but in particular form a vital component in ceramic manufacturing. Kaolin ('china clay') produces a very white color when it is fired, but used alone it is brittle and weak and must be mixed with ball clay to produce a workable, malleable raw material.
Ball clay vs. Kaolin porcelain at cone 6. Left: A porcelain that is plasticized using only ball clays (Spinx Gleason and Old Hickory #5). Right: Only kaolin (in this case Grolleg). Kaolins are much less plastic so bentonite (e.g. 2-5%) is typically needed to get good plasticity. The color can be alot whiter using a clean kaolin, but there are ...
Ball clay is extracted from the ground by surface working (open pit method), underground mining having ceased in 1999. Extraction involves excavators and dump trucks to selectively remove individual grades of clay to storage and blending facilities. The ratio of waste to clay is variable, but overall is in the order of 1 to 1.5. Ball clay ...
Ball Clay (OM4 in this case) always has less alumina and more silica than kaolin - so it takes more ball clay to get the same amount of alumina - then you have too much silica so you need to remove some. To get the same glaze use 14 OM#4 and reduce the silica to 25. Replacing kaolin with ball clay helps suspend glazes better and also will
Like ball clay, kaolin is fine and very plastic. Fire clays are another important class of clays. These highly refractory clays have a very high fusion point, which is a great feature when you are attempting to balance the temperature range of your claybody. Like ball clays, fire clays are also kaolinitic in nature, and they are commonly used ...
