WBC Clay (White Burning Clay)
WBC Clay is a low-iron white firing clay used in ceramic and porcelain formulations where brighter fired appearance and consistent body response are important. Performance varies by grade and firing cycle, and is confirmed through batch testing.
Key Technical Characteristics
Low-iron composition for white firing response
Suitable for porcelain and white-body formulations
Controlled physical and firing behavior
Consistent ceramic body development support
