Ball Clay is a variety of Kaolinite, like china-clay. It differs from china-clay in having high plasticity and less refractoriness. In chemical composition, ball and china clays do not differ greatly except that the former contains a larger proportion of silica. It has derived its name from the practice of removing it in the form of ball-like lumps from the clay pits in the UK.

Conclusion. In this article, we discussed the four major types of clays: Earthenware, Stoneware, Ball clay, and Porcelain. All of these clays have different firing temperatures, colors, textures, and uses. Even if the clays are essentially composed of similar minerals impurities. Picking the right clay is perhaps the first step to making pottery.

An improved gunning composition for use in the steel industry includes between 60-75% by weight of a refractory base material, 10-20% by weight of silicon carbide, 7-15% by weight of ball clay, 4-8% by weight of a silica binder material, and, optionally, 5-10% by weight of a graphite material. The silica binder replaces binders composed of petroleum pitch or clay.

Ball Clay (or plastic clays), is a kaolinitic mineral clay and a member of the phyllosilicate group of minerals. It occurs generally as an aluminium silicate comprising weathered forms of quartz, mica and kaolinite. Although similar in chemical composition, BALL CLAY is not as common as kaolin and differs substantially in physical characteristics.
