Imerys mines and processes ball clays with a range of different properties. By blending selected clays from different loions, Imerys can provide high quality products for a range of ceramic appliions. Ball clay, or 'plastic clay' as it is also known, is an extremely rare mineral, only found at a handful of loions around the world.

Properties. The defining mechanical property of clay is its plasticity when wet and its ability to harden when dried or fired. Clays show a broad range of water content within which they are highly plastic, from a minimum water content (called the plasticity limit) where the clay is just moist enough to mould, to a maximum water content (called the liquid limit) where the moulded clay is just ...
Ball clay Definition of Ball clay at Dictionary. 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.
Ball Clay Properties. Ball clayplastic clay 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 Imerys. Combined with kaolin, ball clays provide the cohesion and workability necessary for the creation of ceramic parts such as sanitaryware used with kaolin, feldspar and quartz in tableware and whiteware, ball clay confers high plasticity and a good whitefired color to the end product in wall and floor tiles, ball clays are prized for their plasticity and bonding properties
Ball Clay Heritage Society The Society was formed in February 2000 to further understanding of the geology, occurrence and properties of the ball clays of Devon and Dorset and to preserve the history and heritage of clay production, transport and use, To that end, the Society is assembling an irreplaceable collection of artefacts, store of archive materials and a range of .
GLAZE CLAY #1 is a ball clay mined in Kentucky and is produced by Old Hickory Clay Company. Mixed from a powdered state, it was mixed softer than required to ensure thorough wetting and left to dry overnight to the desired consistency. Sometimes, illite/smectite (I/S) mixedlayered minerals also occur. Ball clay is made up of very fine clay particles or clay crystals. Ball clay .
Most ceramic products are claybased and are made from a single clay or one or more clays mixed with mineral modifiers such as quartz and feldspar. The types of commercial clays used for ceramics are primarily kaolin and ball clay. Process Description1,35 Figure presents a general process flow diagram for ceramic products ...
· plasticity of ball clays before firing, related to share of particular clay minerals and their structural order; it affects properties of ceramic batch after pressing and drying. Applied clays should also exhibit very low content of colouring oxides, influencing whiteness of .
Ball clay is a very useful addition to different types of clay. However, it also has properties that need mean it needs to be handled with care. These properties are as follows: Ball Clay Can be Tricky to Dry. Because of its high water content, ball clay shrinks a lot when it dries. This needs to .
Abstract: Ball clays are finegrained, high plastic sedimentary clay, and when fired will produce a light or near white colour. In this study, the chemical properties of ball clay from Kampung Dengir were characterized by using XRay Powder Diffraction (XRD) and Ther mo Gravimetric Analysis (TGA) techniques.
Clay soil has a distinctive texture. When dry, it holds its shape, and does not crumble like sand. When it is wet, it can be sculpted and molded into different shapes. To test the amount of clay in your soil, roll a moist chunk into a 1inch ball and press it flat between your thumbs.
Ball Clay Heritage Society The Society was formed in February 2000 to further understanding of the geology, occurrence and properties of the ball clays of Devon and Dorset and to preserve the history and heritage of clay production, transport and use, To that end, the Society is assembling an irreplaceable collection of artefacts, store of archive materials and a range of photographs, films.
Ball clay is extracted using mechanical equipment, of which the most popular are hydraulic "backhoe" excavators, that work as "benches" cut into the quarry to access the seams of clay. Individual raw clay selections are blended carefully according to predetermined recipes to provide a product with a consistent and predictable range of characteristics and behavior.
Properties. The defining mechanical property of clay is its plasticity when wet and its ability to harden when dried or fired. Clays show a broad range of water content within which they are highly plastic, from a minimum water content (called the plasticity limit) where the clay is just moist enough to mould, to a maximum water content (called the liquid limit) where the moulded clay .
Ball clays are kaolinitic sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% 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 finegrained and plastic in nature, and, unlike most earthenware clays, produce a fine ...
