Ball clay is a fine-grained, highly plastic clay mineral valued for its ability to enhance workability in ceramic bodies. It primarily contains fine kaolinite particles, along with minor amounts of other clay minerals, mica , and quartz. This unique composition delivers exceptional plasticity and green strength, making ball clay essential in the manufacture of porcelain, sanitaryware, and tiles. Ball clay enhances both the formability and mechanical strength of unfired ceramic products and improves rheology in ceramic slips and engobes for uniform drying and reliable fired performance.
