Considered by some as a stoneware clay, it fires very white and is used in white firing porcelains and stoneware for its excellent plasticity. The company describes it as a fine-grained engineered blend, well known for its excellent plasticity and fired properties. This consistent blend is suitable for a wide variety of forming processes, where a high degree of plasticity is required, such as dry pressing, jiggering, ram pressing and casting.
