Ball clay is a mineral formed from the weathering and transportation by water of parent rocks which are deposited in ancient river basins from where it is extracted. Imerys Ceramics has at its disposal ball clays with a range of different properties.
Artesia offers ball clays with a wide range of properties. By blending selected clays from different locations our high quality products have broad applications. Ball clays are an extremely rare mineral found in very few places around the world. They usually contain three dominant minerals: from 20-80% kaolinite, 10-25% mica, and 6-65% quartz.
Ball clays are kaolinitic sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters.
Ball clays are sedimentary in origin. Ancient rivers and streams washed kaolinite (formed from decomposed granite) from its parent rock. As the streams flowed from upland area they mixed with other clay minerals, sands, gravels and vegetation before settling in low-lying basins to form overlaying seams of ball clay.
The paper presents the results of investigations of mineralogical, grain and chemical composition, and ceramic properties of 18 white-firing ball clays from five producing regions in eastern and central Europe. Relationships between the bending strength of the clay after drying and its grain size and mineralogical composition were studied.

Ball clays exhibit highly variable compositions and consist of a mixture, primarily of kaolinite, mica and quartz, with each contributing different properties to the clay. The crystallinity of the key component, kaolinite, has a marked influence on ceramic performance.
Notes. The term 'ball' traces to historic mining in England where large chunks of the clay were cut from the bank in ball shapes for transport to processing. There are hundreds of different ball clays available. Potentially they should vary widely in plasticity, particle size, raw color, and drying properties.But in practice, most are remarkably similar.

Ball clay is a general term for many clays. It comes from the practice of digging the clay out of the open pits in convenient blocks of about 12 kb, called balls. These clays are always plastic, and mostly cream and vitrify in the 1100°C to 1200°C (2012°F to 2192°F) range."-The Potter's Dictionary of
The ceramic properties of plastic ball clays depend on the content of the clay minerals (especially I/S minerals) but also on the level of crystallinity of kaolinite and illite. These features influence grain size distribution and specific BET surface area of the clays. Plastic ball clays contain commonly large amounts of grains < 1 μm (50 ...

Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types. Major domestic markets for these clays are as

Relations between quality of ball clays applied in raw materials batches for manufacture of porcelain tiles, and physical properties and microstructure of obtained tiles, were investigated.
Clay mineral - Clay mineral - Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract--Three ball clays (SP from England, TSMA from France and UK from the Ukraine) were characterized for their dry and wet colloidal properties. On the basis of X-ray diffraction and chemical analyses the clays were classified as kaolinite-rich clay, smectitic kaolinite-rich clay and illitic kaolinite-rich clay.
particular clay and may often lead to new areas of applications (Baccour et al., 2008). Two types of clays are generally used—kaolin and ball clays. Kaolin is one of the most useful industrial minerals with a wide range of applications; kaolinite (Al 2 Si 2O 5 (OH) 4) is the main mineral in both clay types and this is composed of alternate ...
