Ball clays are kaolinitic clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz, as well as organic matter. Ball clay is formed from the weathering and transportation by water of parent rocks. Seams in the same deposit will vary in composition, depending on the quantity of the principal and accessory minerals. Ball clays are fine-grained, highly plastic clays, which are principally used in the manufacture of ceramic whiteware and sanitary ware where they are appreciated for their plasticity, unfired strength and their light colour on firing. Selected clays can even give pure white end products. Among others, ball clays are also used in refractories, in polymers, in adhesives and sealants and in horticulture as soil amendments. Imerys mines ball clay from its deposits in England, France, Thailand and the United States. We also make use of ball clay blending platforms in Egypt, India, Indonesia and Brazil to ensure that we produce ball clays that address the technical challenges of each specific region.  By carefully processing and blending selected clays from different locations we can provide high-quality products for a range of applications.
