Imerys ball clays are prized for the production of ceramics tableware and sanitaryware where they are valued for their plasticity, excellent workability, unfired ...
Ball Clay. 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.
The term Bentonite was first used for a clay found in about 1890 in upper cretaceous tuff near Fort Benton, Montana. The main constituent, which is the determinant factor in the clay's properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montmorillon, in Southern France.
Using Ball Clay for Alternative Items in the Bathroom. Finally, we have ball clay. This is a little different because of its mineral properties and the way that it is used to create some common items. The difference here all comes down to the plasticity of the material and its lack of mineral impurities.
Process Properties. As a ball clay, thus it improves plasticity of any body recipe to which it is added. However it will also increase drying shrinkage, slow down drying time and increase the difficulty of drying ware without cracking.. A2 contains some soluble salts.These are hostile to the deflocculation process so this material is not suitable in casting body recipes.

In foundry shop, the clay acts as binder which may be Kaolinite, Ball Clay, Fire Clay, Limonite, Fuller's earth and Bentonite. Binders included in the organic group are dextrin, molasses, cereal binders, linseed oil and resins like phenol formaldehyde, urea formaldehyde etc. Binders of organic group are mostly used for core making.
Combined with talc, feldspar, quartz/silica and kaolin, ball clays are utilized for their plasticity and bonding properties. Glazes and engobes Ball clays are also used in the production of coatings for ceramic products to ensure the perfect finish. Refractory clays
3. Kaolin has no appreciable reactions to PH levels, ball clay/s do. PH levels are the primary indicator of reduction potentials; which in turn predict the plasticity of clay. This is also the reason sodium is the flux of choice of kaolin (porcelain), and potassium is the flux of choice for stoneware (ball/fire clay).
The properties of ball clay render it a very desirable ingredient of ceramic bodies and it is also used as a filler for natural and synthetic rubbers. Conventionally, ball clay is produced by digging the raw clay from the ground in the form of blocks of plastic material which contain about 20% by weight of water.
The paper presents the results of investigations of mineralogical, grain and chemical composition, and ceramic properties of 18 white-firing ball clays from five producing regions in eastern and central Europe. Relationships between the bending strength of the clay after drying and its grain size and mineralogical composition were studied.
The US Geological Survey lists six types of clay mined in the United States: common clay, kaolin (China clay), bentonite, ball clay, fuller's Earth, and fire clay, and each has a number of different uses: Common clay is mostly used for bricks, cement, and aggregate. Kaolin is widely used for making glossy paper.
The demand for wound management treatment especially advanced and active wound care products is huge. In this study, the scaffolds were prepared from gellan gum (GG) incorporated ball clay (BC) at different concentrations to investigate their swelling properties, water vapor transmission rates (WVTR), mechanical characteristic and thermal behavior.
The fluxing agent usually used to reduce the sintering temperature of ceramic production. In order to achieve this study, the potassium feldspar had used as a fluxing agent in range between 15.2 - 42.5 %. The mixture of slurry was formulated by using ball clay, silica, polyethylene glycol and potassium feldspar to produce the ceramic pieces.
A typical ball clay powder is light grey (from lignite) or cream color and fires to a buff or cream (with some soluble salt deposits on the fired surface). Ball clays tend to be quite refractory (PCE 28-34) and some less processed deposits are sold as fireclays.

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 be factored in when making pottery.

Ball clays exhibit highly variable compositions and consist of a mixture, primarily of kaolinite, mica and quartz, with each contributing different properties to the clay. The crystallinity of the key component, kaolinite, has a marked influence on ceramic performance.
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.
Kaolin is a rock from which the clay mineral kaolinite is derived. This one has been used for millennia as the principal ingredient in porcelain tableware. Today Imerys kaolins bring critical properties to a host of end applications ranging from paper to paints, fiberglass to cosmetics and pharmaceuticals.
