CHINA CLAY |
| |
CHINA CLAY is kaolinised feldspar - they are highly valued for their whiteness. Pure kaolin is necessary for the manufacture of porcelain and other fine china; impure varieties are used in making pottery, stoneware, and bricks; as filler for pigments; and in the manufacture of paper. China clays have poor plasticity so they are often used in conjunction with additives - usually ball clay and Bentonite. As a general rule china clays are quicker to cast than sedimentary clays. They are highly valued for their whiteness, hence their use in bone china. Shrinkage of clays fired at 1300ºC is about 12%.

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. It also is sometimes referred to as plastic clay. Ball clays usually contain three dominant minerals: from 20-80% kaolinite, 10-25% mica, and 6-65% quartz.

FIRE CLAY |
| |
FIRE CLAY is the refractory nature of the high alumina fireclays that make them so valuable in the manufacture of firebricks and other heat resistant ceramics such as saggars. A clay with refractory characteristics (resistant to high temperatures), and hence suitable for lining furnaces (firebrick). Its chemical composition consists of a high percentage of silicon and aluminium oxides, and a low percentage of the oxides of sodium, potassium, iron, and calcium |

BENTONITE |
| |
BENTONITE is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. Bentonite presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. The special properties of bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications.
