chemical analysis of ball clay

Ball clay Wikipedia

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 Clay Digitalfire

Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 10-20% for Tennessee ball clays). Ball clays are very plastic and much finer-grained than kaolins. They are easily slaked in water when dry.

What is Ball Clay? Industrial Minerals Association

Ball clays usually contain three dominant minerals: from 20-80% kaolinite, 10-25% mica, and 6-65% quartz. In addition, there are other 'accessory' minerals and some carbonaceous material (derived from ancient plants) present.

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 undergoes limited processing. Most is size reduced and

Chemical composition of clays. Most clay is aluminum oxide, silicon dioxide, and water. These are the primary elements which fuse together to form a ceramic object. However, many additives can go into clay, affecting its sturdiness, color, texture, or firing range. Sand may be added to some clay, for toughness, viscosity, and texture. Sand is also rich in vitrifying silica. Vitrification is
