Purbeck Ball Clay has been used for thousands of years, but large scale commercial extraction began in the middle of the 18th century and continues today. The principal workings were in the area between Corfe Castle and Wareham.
Ball clay is used as wall & floor tiles in the construction industry by mixing with talc, feldspar, kaolin, and quartz/silica, as ball clay increases the plasticity and bonding properties. With increasing investments in the construction industry worldwide, the use of tiles for the walls and floors is increasing resulting in the increased consumption of ball clay.
The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BM-Clay1 to BM-Clay6). Ground clays were then characterized by particle size measurement, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy analysis, and …
Since the 1950's ball clay has also been used in a wide range of non-ceramic applications, for example in coating fertiliser 'prills' (pellets), as a filler in rubber and linoleum and as an extender in animal feed stuffs. By 1970 annual sales had grown to 700,000 tonnes, and by 2000 to just over 1 million tonnes, more than 75% of which ...
What is Ball Clay? 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.
BALL CLAY HERITAGE SOCIETY Twentieth Annual General Meeting: 12 March 2019 CHAIRMAN'S ANNUAL REPORT Welcome to the 20th AGM of the Ball Clay Heritage Society. As usual I would like to update you with what the Society has been doing over the last twelve months. The General Committee met
Ball clay, or 'plastic clay' as it is also known, is an extremely rare mineral, only found at a handful of locations around the world. It is a kaolinitic clay that commonly consists of 20–80% kaolinite, 10–25% mica, 6–65% quartz as well as organic matter.

Ball clays or plastic clays are fine grained, highly plastic sedimentary clays, which fire to a light or near white colour. They are used mainly in the manufacture of ceramic whiteware and are valued for their key properties of plasticity, unfired strength and their light fired colour.
Ball clay definition, a fine dark kaolinic clay that turns white or nearly white when fired, used in the manufacture of a wide variety of ceramic wares in combination with other clays for its exceptional bonding properties and plasticity. See more.

The name ball clay is derived from the original method of mining this plastic clay in England, where it was cut from the bank in a form of balls weighing 33 lbs. This expression was adopted to a wide range of clay materials which cannot be categorized as kaolins or fire clays. 6 The majority of ball clay is used for production of china and tiles.
Clay courts give the ball a lot of bounce. So you might want to pick a ball that gives less bounce. If you pick a ball that has high altitude and plays with it in a clay court, the ball will get too high and it will make the game too difficult for both players. So pick a ball with low to medium altitude for playing in a clay field.
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.
Mined ball clay typically exhibits a moisture content around 28%. It may be allowed to naturally dry and then sold as-is (this makes up a small portion of the ball clay market), or after natural drying, it may be further dried down to 8-10% moisture.
Ball Clay 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.
Ball Clays is a fine-grained, highly plastic sedimentary clay, which fire to a light or near white color. They are used mainly in the manufacture of ceramic whiteware and are valued for their key properties of plasticity, which makes them easy to mould, their unfired strength and the fact that when fired they have a light color.

Furthermore, ball clay is known as having a high level of plasticity because it consists of beautiful particles. It also has excellent binding and flowability. The melting point of this mineral is somewhere between 1.250 °C to 1.350 °C. Primary and Secondary Clay. Ball Clay is categorized as secondary or sedimentary clays.
BALL CLAY. 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 clays usually contain three dominant minerals: from 20-80% kaolinite, 10-25% mica, and 6-65% quartz.
