What Are the Four Types of Clay? - Pottery Crafters
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.

Plastic ball clays are commonly composed of kaolinite (25–80%), illite and mica (10–30%), and fine-grained quartz. Sometimes, illite/smectite (I/S) mixed-layered minerals also occur. A small amount of organic matter—up to 0.5 mass %—is also typical ( Wilson, 1998 ).

Ball clay. Ball clays are kaolinitic sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz. Localized 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 fine-grained and plastic in ...
Ball Clay - Digitalfire
Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 10-20% for Tennessee ball clays). Ball clays are very plastic and much finer-grained than kaolins. They are easily slaked in water when dry.

CLAY MINERALS - USDA
Clay minerals refers to a group of hydrous aluminosili-cates that predominate the clay-sized (<2 |xm) fraction of soils. These minerals are similar in chemical and structural composition to the primary minerals that originate from the Earth's crust; however, transformations in the geometric arrangement of atoms and ions within their

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.
clay mineral - Chemical and physical properties | Britannica
clay mineral - clay mineral - Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silicate structure.
What is Kaolin | The Kaolin and Ball Clay Association
Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral's whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.

Chamotte | Imerys
Clay minerals, such as kaolinite, are alumino-silicate hydrates and can be represented by the chemical formula Al 2 O 3.2SiO 2.2H 2 0. When heated ("fired"), these hydrates lose water and transform to a combination of mullite (3Al 2 O 3.2SiO 2), cristobalite (SiO 2) and a glassy phase which constitutes chamotte. PHYSICAL PROPERTIES.
