Like all phyllosilicates, clay minerals are characterised by two-dimensional sheets of corner sharing SiO 4 tetrahedra and/or AlO 4 octahedra. The sheet units have the chemical composition (Al,Si) 3 O 4. Each silica tetrahedron shares 3 of its vertex oxygen atoms with other tetrahedra forming a hexagonal array in two-dimensions.

Ball clay when taken orally over a long period of time can cause granulomas of the stomach. Exposure to quartz (the most stable and common form of crystalline silica) is responsible for the majority of clinically diagnosed silicosis.
Our range of Ball Clay is high on demand in the market. It is a highly plastic variety of clay of kaolin group. The high plasticity in ball clay is attributed to its particles being very fine grained. The pyrometric cone equivalent of ball clay hardly exceeds 33. Over 85 % of the particle sizes present in ball clay .
earths. Clay is formed by the mechanical and chemical breakdown of rocks. The six-digit Source Classification Codes (SCC) for clay processing are as follows: SCC 3-05-041 for kaolin processing, SCC 3-05-042 for ball clay processing, SCC 3-05-043 for fire clay processing, SCC 3-05-044 for
OM#4 ball clay is variable in nature and tends to be more vitreous than some of the more refractory ball clays that are available. It has some soluble salts which can give a brown coloration to the surface, so barium carbonate may be needed to precipitate these.
The ball clay:kaolin mix can be altered to change body plasticity without significantly affecting the maturing temperature. In North America, most commercial ball clays are mined in the southeastern US. Ball clay deposits are common and were laid by the action of slow moving water with an acidity that tended to flocculate and settle the clay.
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 ...

Clay deposits and clay minerals generally vary in nature, no two or more deposits can have exactly same clay minerals and frequently different samples of clay from the same deposits differ. Their physical and chemical properties (swelling ability, plasticity, cation exchange capacity etc)
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. These adsorbed ions ...

Ball clay is an extremely rare mineral found in very few places around the world. Its name dates back to the early methods of mining when specialized hand tools were used to extract the clay in rough cube shapes of about 30 cm. As the corners were knocked through handling and storage these cubes became rounded and 'ball' shaped.
