Clay & Industrial Minerals•Batch Lab Tested
Ball Clay
Ball clay is a fine-grained plastic sedimentary clay used in ceramic bodies where workability, green strength, and predictable firing behavior are essential. The supplied material is selected from multiple quality grades to support ceramic and sanitaryware production requirements.
Key Technical Characteristics
High plasticity and smooth body workability
Strong green and dry handling strength
Consistent firing range across ceramic formulations
Suitable for tiles, sanitaryware, and porcelain bodies
