Found both as primary and secondary clay deposits (Kaolinite is the major mineral constituent), and they are typically coarse in particle size and, as a result, are non-plastic. In glazes it is a major source of Alumina. If used in large amounts in a glaze, it can produce a matt texture. It is the principal component of porcelain bodies, and will produce white stoneware bodies in a wide temperature range (cone 5-16) due to its low Iron content
